Proceeding our preliminary forray into the sector of UPSes, these days we are having a look at our 2d UPS – and our first lithium-ion founded unit – Vertiv’s Edge Lithium-Ion. The rackmount-capable UPS comes with a focal point on top of the range and excessive potency, permitting the 1500 VA unit we are reviewing these days to energy rather a lot as excessive as 1350 Watts, a hefty quantity for a moderately modestly-sized UPS.

Despite the fact that Vertiv is a emblem title that the majority house PC customers are ignorant of, they’re probably the most oldest and biggest IT infrastructure design & producers on this planet. The unique corporate was once based in america again in 1946 and advanced along the first actual computer systems, growing cooling and gear answers for important IT infrastructure. Lately Vertiv is an organization with 19 production websites international and annual revenues more than 4 billion USD.

In spite of the corporate’s dimension and recognition, Vertiv was once nearly completely fascinated about commercial and important programs, neglecting the house/retail marketplace. Extra lately, prior to now few years, the corporate has been shyly taking steps downwards, looking to seize items of the fanatic phase of the house/administrative center PC marketplace.

The topic of these days’s evaluate, Vertiv’s Edge Lithium-Ion 1500 VA UPS, is without doubt one of the more practical and more economical merchandise that the corporate produces. Even so, its options and specs are a great deal awesome than nearly all of consumer-grade UPS to be had these days, owing to Vertiv’s design heritage in addition to the truth that that is unambiguously (and unabashedly) a high-end UPS in each and every sense of the phrase. Particularly with the excessive price of lithium-ion batteries, Vertiv has made positive to construct a top quality unit round that battery, all of which is mirrored within the £950+ ($1200+) retail ticket.

The Edge Lithium-ion circle of relatives is available in 3 capacities; at 1500VA, what we are reviewing these days is in truth the smallest of the circle of relatives. Nonetheless, with a 240 Wh battery and an influence supply machine rated to be 97.5% environment friendly, the 1500VA Edge can run at a complete, 1350W load for nearly 9 mins, and for much longer nonetheless with lighter workloads.

The Edge Lithium-ion lineup is designed for 230V techniques, and whilst Vertiv gives equivalent devices for the 120V marketplace, they do not have a North American identical of the Edge. Nonetheless, if now not for the published specs you would be arduous pressed to inform that the unit is designed for any given area, because the 6 battery-backed sockets are all IEC C14, reasonably than a regional wall socket like Schuko (Sort F). In a similar fashion, the UPS makes use of a C13 socket as an enter, reasonably than depending on an built-in energy cable.

The Vertiv Edge Lithium-Ion 1500 VA UPS

Vertiv provides the Edge Lithium-Ion 1500 VA UPS in an aesthetically easy however very robust cardboard field, with the unit secure through thick packaging foam slabs. Throughout the field, we discovered each same old plastic ft and rack mounting adapters, two load cables, a USB interface cable, and AC energy cables. Vertiv is the one corporate we now have ever encountered that provides all 3 AC cable codecs (US, UK, and EU) along with their product.

Vertiv claims that their Edge Lithium-Ion collection is moderately compact. That stated, the 1500 VA model measures 438 mm × 410 mm × 86 mm (W × D × H), which isn’t in particular compact for a UPS with that roughly output. However on the identical time, for the reason that Edge lineup is designed to be rack-mountable, there may be now not a lot else the designers may just do to restrict the UPS’s dimension given the width necessities.

The Edge Lithium-Ion has an influence issue of 0.9, which means that it might output as much as 1350 Watts.

The LCD display of the UPS can all the time be became on, even though the UPS has been became off, so long as there may be even a tiny little bit of price left within the batteries. As soon as on, the display will show a mimic diagram of the unit’s operational standing and elementary electric figures, such because the enter and output voltage and frequency, and the battery’s standing and estimated runtime.

On the rear aspect of the unit, there’s a same old unmarried AC energy enter IEC C14 plug and 6 C13 output plugs. 3 of the six output plugs are SPI programmable, taking into consideration condition-based keep watch over by way of the unit’s device. A easy however efficient restorable circuit breaker is positioned proper subsequent to the enter plug. The unit has an ordinary USB port for direct-to-PC connectivity, in addition to an not obligatory intellislot interface this is not going to be of any use to house and small industry customers. EU customers will have to observe that the UPS differentiates the Section and Impartial enter wires. Sure EU connectors, with Schuko connector being the top instance, don’t differentiate those two wires. If the AC connector is inserted into the socket with the Section and Impartial wires inversed, the UPS will tell the consumer to rotate the plug. When you see that error and you’re the usage of a non-rotatable plug, then you most likely require a certified electrician to mend your electric set up.


There’s a unmarried fan within the unit, which can handiest activate whilst the batteries are in use – both when the UPS is operating on battery energy, or when it is charging its batteries. The velocity of the fan is variable whilst the unit is operating on battery energy, permitting the unit to handle very low acoustic ranges when frivolously loaded. On the other hand, the fan will burst at most velocity instantly when the AC energy is restored and can keep at most velocity till the batteries are absolutely charged. Because the battery runtime is way shorter than the battery charging time, I would argue that this design defeats the aim of getting a variable fan velocity controller initially.

As is the standard observe with slender UPS designs, many of the entrance fascia is a door that may be got rid of to get admission to the battery compartment. Vertiv designed the door to latch magnetically and will also be got rid of with out the usage of gear, revealing the beefy connector that connects the batteries to the primary unit. The battery is hidden in the back of a steel protect, necessarily forbidding its elimination if the connector is joined. Getting rid of the protect although does require a Philips screwdriver, negating the toolless way of the entrance panel.

The battery nearly is the primary characteristic of this UPS, with the collection using lithium-Ion batteries. Those are considerably dearer than commonplace lead-acid UPS batteries, however they’ve spectacular specs for his or her dimension and can a great deal outlive the ones conventional lead-based merchandise. The only within the 1500 VA model of the Vertiv Edge weighs not up to 4 kg and nonetheless has a capability of 240 Wh. Despite the fact that the lithium-Ion battery is surely dearer than lead-acid batteries of the similar capability, Vertiv claims that the longevity of the lithium-Ion battery makes it economically possible. And and far as we might like to place the ones claims to the check, the most productive we will be able to do is take Vertiv’s phrase at the subject for now, as this battery isn’t but even to be had in retail.

Opening up the chassis finds a big transformer close to the AC retailers and circuitry around the height aspect of the unit. This can be a vintage way for slender designs. The transformer is cooled by way of the chassis itself, receiving minimum to 0 airflow from the fan.

The circuitry is most commonly coated underneath a paper quilt that paperwork a wind tunnel, bettering the cooling houses of the UPS. The usage of paper to shape wind tunnels is a confirmed methodology however maximum fans would be expecting one thing of upper high quality in such a pricey top-tier UPS.

The ability circuitry is spectacular with regards to amount and oversizing, however now not truly so with regards to high quality. The principle 450V/470μF capacitor is provided through Aishi, a rather respected producer however now not one that we’d be expecting to peer in this type of elegant product. The smaller capacitors are a mixture of Jamicon, Aishi, and Elite – all middle-tier producers that we hardly ever see the goods of in the rest higher than mainstream PSUs.


The relays are equipped through Hongfa, a widely recognized and skilled Chinese language producer. The fan may be equipped through Dongweifeng, a Chinese language producer whose merchandise we now and again see in commercial apparatus however by no means in top-quality user merchandise. Looking out across the PCB, one too can simply understand the connector for an exterior battery.

We need to observe that the UPS marketplace isn’t as uncovered because the PSU marketplace, subsequently designers aren’t most often put underneath the microscope about who they supply their number one elements from. Respected producers are respected for just right causes, however the usage of portions from them is continuously finished simply as a lot for optics and advertising and marketing as it’s for exact high quality. It’s going to surely be a while earlier than we see UPS designs with simply top-quality portions in them.

The center of the facility circuitry is 8 ST Microelectronics STGP20H60DF insulated-gate bipolar transistors (IGBTs). Those are top rate elements, being very excessive velocity IGBTs with very low losses, in addition to a very good temperature coefficient. In layman’s phrases, those are able to producing a just about very best sine waveform and handle it even if closely loaded.

Via default, the LCD display shows a mimic diagram of the unit’s present standing and operation. It additionally shows elementary knowledge, such because the chassis temperature, the date, the time, and the situation of the battery. The show turns itself off after a couple of seconds of inaction and can come on once more handiest when a button is pressed. It is usually profitable to notice that the unit has an orientation sensor and the LCD will, through default, robotically alter its orientation relying on whether or not the unit is positioned vertically or horizontally.

The Vertiv Edge Lithium-Ion, being a high-end product, gives complicated configuration choices by way of its LCD display. Customers can alter the enter sensitivity, the output voltage and frequency, in addition to complicated battery control choices. There’s even a atmosphere that permits for rudimentary temperature repayment for the battery’s parameters, that could be helpful for scenarios the place the UPS is positioned someplace that may get overly scorching or chilly.
