Note!
To calculate the correct value of regenerating power it is necessary to note, that the real mo-
mentary regenerating power is dependent on the real existing main circuit voltage at any time.
To calculate the regenerative power the following formula should be used:
P = U

(during regenerative operation: cos

= 1)
The maximum possible regenerative power is calculated based on the momentary RMS mains
voltage and the maximum RMS current of the respective device.
Example:
Model RHD-50-... with rated feedback power of 50kW, maximum rated RMS current 72A (re-
fer to technical data), nominal mesh voltage rating e.g. 400V.
From that results: P=400V x 72A x
√

=49883W, that’s about 50,0kW
If the momentary RMS mains voltage is only 395V or even lower for a short time, the maxi-
mum possible regenerative power is reduced as well:
P = 395V x·72A x
√
3
= 49259W, that’s about 49,3kW.
