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
LO base load
7.5 kW ... 90 kW
4 kHz
The pulse frequency can be increased in 2 kHz steps. A higher pulse
frequency reduces the permissible output current.
Regenerative energy
IP20
HO base load
-10 °C ... +50 °C (14 °F ... 122 °F)
LO base load
-10 °C ... +40 °C (14 °F ... 104 °F)
-40 °C ... +70 °C (-40 °F ... 158 °F)
< 95% RH - condensation not permissible
Up to 1000 m (3300 ft) above sea level
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
The permissible line operating voltage
depends on the installation altitude
150% overload for 57 s
200% overload for 3 s
100% HO base load for 240 s
110% overload for 57 s
150% overload for 3 s
100% LO base load for 240 s
Higher operating temperatures
are possible when the rated
power is reduced (derating)
Higher altitudes are possible
when the rated power is
reduced (derating)
Frequency inverter
