Inverter UPSs cover 1 to 3 kVA

Power Electronics / Power Management
PHD Power has acquired the distributorship for the IV range of inverter UPSs.
Traditionally, battery backup systems have come in two basic flavours – UPSs and inverters. While UPSs have the advantage of either being online or having transparent transfer times, they typically lack the high current chargers required to charge large banks of batteries for extended backup times. On the other hand, while inverters provide superior charging capacities, they often lack the transparent transfer times required to keep sensitive equipment running during blackouts.
The IV range of UPSs have a transfer time of under 6 ms which makes them well suited for use in sensitive systems. They also come standard with AVR operation under normal conditions, which provides protection against voltage fluctuations. Their most distinguishing characteristic is that they come standard with a 25 A supercharger enabling them to accommodate up to 250 AH battery banks and providing extensive battery runtime.
Various units are available varying from a 1000 VA to 3000 VA, all of which produce a pure sine wave output and incorporate overload, short circuit and thermal protection, as well as surge protection.
