Capacity
415V 3 phase, 50/60Hz: 100kW in 1.25kW steps
240V 1 phase 50/60Hz: 33kW in 400W steps

Other AC voltages
Lower AC test voltages can be applied; the maximum power is reduced accordingly.

For example:
220V 3 phase, 50/60Hz: 28kW in 350W steps
110V 1 phase, 50/60Hz: 7 kW in 85W steps

DC voltages
A dual AC/DC model is available at extra cost, having all the capabilities of the standard version plus an additional rating of 0 – 190A (42kW) at 220V DC.
