Specifications

UPS WHAD is the evolution of the single-phase

online double conversion UPS for small and

medium power applications. As Metasystem Energy’s

UPS, WHAD stands out for its advanced technology

and also for its attractive and pioneering design. It is

available in 800 VA to 6000 VA versions.

The

UPS WHAD

devices with on-line technology (VFI)

make a double conversion of the electric current on the

input (AC-DC-AC).

The output remains absolutely independent of the

input both for voltage and frequency value. If the input

voltage is no longer suitable, the energy required for

the second conversion is drawn from the batteries.

All this takes place without actuation time. The double

conversion system becomes more  exible and reliable

by using an automatic by-pass circuit. The by-pass will

cut-out the UPS if overloads or faults occur. In short, the

online double conversion UPS guarantees the highest

protection against any electrical interference.

This means that it is ideal for protecting servers

and company networks, storage systems, industrial

automation, security and video surveillance systems.
