Technical data
14 Mono Power Unit BUM 62 T
5.99009.03 Baumüller Nürnberg GmbH
1. Voltage difference between phases must no exceed +/- 1.0 %.
2. According to EN 61131-2 (Table 5).
With a supply voltage < 24 V the fan power is reduced. Therefore, it may be necessary to reduce the
output current additionally.
3. All ratings refer to a connection voltage of 400 V and a supply voltage of 24 V.
4. The output voltage is a pulse-commutated DC. The setting range refers to the r.m.s. value of the
fundamental wave.
5. The output frequency depends on the controller used.
6. R.m.s. value at an ambient temperature of 40 °C.
7. The unit provides the rated/maximum output current up to the connection voltage. When the input
voltage exceeds the rated voltage, reduce the output currents at constant output power
proportionally.
Characteristic 1: Output currents in relation to the connection voltage.
8. The rated output current must be reduced between 40 °C and 55 °C. The rated output current is
calculated according to the following formula:
Example: Rated output current = 100 A, ambient temperature = 46 °C.
The rated output current must therefore be reduced to: 82 A
9. Maximum duration of the peak output current is 120 s. The duration depends on the motor current
and the temperature of the heat sink. See Technical Description/Operating Instructions of the
controller (V-controller: P139).
10. Chopping frequency of the inverter.
(see description parameter P103 in the description of the V-controller)
