8.5 Common technical data, PM250 Power Modules
PM250
Feature Version
Line operating voltage 3 AC 380 V … 480 V ± 10% The permissible line operating voltage
depends on the installation altitude
Input frequency 47 Hz … 63 Hz
Power factor λ 0.9
The Power Module PM250 can either be operated with high overload
(HO) or low overload (LO). In order to avoid overtemperature of the
Power Module, after the overload, as a minimum its load must decrease
back to the base load (HO base load or LO base load).
HO base load
5.5 kW ... 75 kW
150% overload for 57 s
200% overload for 3 s
100% HO base load for 240 s
Overload capability
LO base load
7.5 kW ... 90 kW
110% overload for 57 s
150% overload for 3 s
100% LO base load for 240 s
Pulse frequency 4 kHz
The pulse frequency can be increased in 2 kHz steps. A higher pulse
frequency reduces the permissible output current.
Braking methods Regenerative energy
Degree of protection IP20
HO base load
-10 °C … +50 °C (14 °F … 122 °F)
Operating temperature
LO base load
-10 °C … +40 °C (14 °F … 104 °F)
Higher operating temperatures
are possible when the rated
power is reduced (derating)
Bearing temperature -40 °C … +70 °C (-40 °F … 158 °F)
Relative humidity < 95% RH - condensation not permissible
Installation altitude Up to 1000 m (3300 ft) above sea level Higher altitudes are possible
when the rated power is
reduced (derating)
Standards UL, cUL, CE, C-tick, SEMI F47
In order that the system is UL-compliant, UL-certified fuses, overload
circuit-breakers or intrinsically safe motor protection devices must be
used
