1)
All rated values refer to a DC link voltage of 540 V, a control voltage of 24 V and an environmental temperature of 40 °C.
2)
Using the power choke listed in Z Power chokes – on page 300 at a power supply with U

= 0.4 %.
3)
The output voltage is a pulsed DC voltage. The operating range refers to the RMS of the fundamental wave.

RMS at an environmental temperature of 40 °C.
6)
At rated power supply voltage the unit supplies rated / maximum output currents. With input voltages above the rated power supply
voltage the output currents must be reduced at constant output power.

The input current must be reduced between 40 °C and 55 °C. See correction factors at changed operating conditions Z Environmental
temperature – on page 57.
8)
The peak output current is supplied for the maximum peak current period for the motor at the first acceleration (cold power unit). The in
fact possible overload time is dependent on the preload of the device and on the heat sink temperature, it is determined by the overload
monitoring of the device.
9)
For cooling versions S and A, only.
10)
If UL508C is complied with: max. 4.0 A.
