Standard 230/400V, 50 Hz and 277/480V, 60 Hz with delta/star connections.

10% overload for one hour every 6 hours is normally accepted. Short overloads can be very high (three times the rated current).

Voltage accuracy:
± 4% from no load to full load, cosϕ = 0.8 at constant rotation speed.

Short circuit current:
In case of short circuit the permanent current exceeds rated current by three times, ensuring the correct operation of protections.

Output voltage wave form:
The low harmonic content (<5%) allows supplying any type of load, including distorting loads.

  • Compact and easy to assemble
  • High starting capacity
  • Possibility to supply any type of load
  • High efficiency
