Range of UPS Products from Vertiv

Specialist Power Systems have been an Official Partner with Vertiv since 2002, which has given us an in-depth knowledge of their extensive portfolio of Uninterruptible Power Supplies.
We have 4 former Vertiv employees, offering extensive in-house experience in both sales and service plus Vertiv products come with up to a 5-year warranty for that extra peace of mind.
Previously known as Liebert, Liebert-Hiross and Emerson Network Power incorporating the Chloride brand, Vertiv is the new name for one of the industries long-established manufacturers.

What is an Online UPS ?

An online or double conversion UPS takes the input AC (Alternating Current) mains and supplies a rectifier which then converts this AC source into DC (Direct Current). The batteries are then usually connected to the DC bus created by the rectifier. Charging of the batteries can be done directly via the DC bus or via separate DC Charging circuit.

The DC supply from the rectifier supplies the Inverter section so that the load is always protected by the inverter and thus maintains a constant output supply regardless of the mains input voltage. Whilst the inverter tracks and synchronises its output waveform to that of the incoming supply the output voltage and frequency are maintained at a constant preset value. The ability to synchronise with the mains allows the UPS to switch from inverter to mains supply seamlessly in the event of a fault, overload or for maintenance purposes.

In the event of a mains outage the DC Bus and inverter are supplied directly from the batteries without any break in output supply.

The conversion from AC to DC and back to AC offers the best protection from all mains deviations and is where the term double conversion is derived.

What is a Line Interactive UPS ?

A line-interactive UPS keeps the inverter online at all times and simply switches from charging mode to battery power in the event of a power failure.

With this topology, the UPS inverter is always online and thus the protected load benefits from a constant preset output voltage. When the input AC power (mains supply) is within tolerance, the UPS inverter acts in reverse and is able to charge the batteries. If the input power fails, the transfer switch will open and the power will flow from the battery, through the inverter to the UPS load. A line interactive UPS also incorporates an automatic voltage regulator (AVR) which utilises  transformers to either boost or reduce the incoming supply should it fall just outside of the preset input tolerances. This feature prevents the batteries from being discharged when the input source is unsteady or unreliable but only slightly outside of an acceptable voltage window. There will also be additional filtering and there is no break in output supply in the event of a mains disturbance as the inverter is always connected to the critical load.

Who are Vertiv ?

With a history of industry-changing solutions and a well-earned reputation for innovation, Vertiv continues to raise the bar in the UPS world.

Vertiv offer the expertise you need, the reliability you demand, and the resources that a global partner can provide. The company traces their roots back to the beginning of the information age, but the organisation began to take shape in 2000 when Emerson brought its critical infrastructure technologies together under the Network Power umbrella. By 2016 the solutions provided by Emerson Network Power, as well as the people that stand behind them, were strong enough to stand alone as Vertiv – which you see today.

When you cannot afford for your critical infrastructure to go down you can rely on Vertiv. They have built their products around delivering reliable facilities and IT Infrastructure optimisation solutions that assure business critical continuity.

Vertiv provide the ideal and complete solution for your business: a product range that brings together everything you need in order to have your business up and running at any moment, but at the same time have quicker and easier access to the infrastructure.

As a Vertiv approved supplier every Vertiv UPS purchased from us comes with an advanced replacement or parts and labour warranty up to three-years depending on UPS. This combined with our industry leading support makes Vertiv Uninterruptible Power Supplies an ideal choice for your UPS power protection.
