Power Modules
3.1 Description
Characteristics of Power Modules
● Design for 380 V 3 AC to 480 V 3 AC from 210 A to 490 A
● Suitable for TN, TT, and IT supply systems
● Liquid cooling
● Short-circuit/ground-fault-proof
● Electronic rating plate
● Operating status and error status via LEDs
● DRIVE-CLiQ interface for communication with the Control Unit and/or other components
● Integration in system diagnostics
● The Power Modules communicate with the higher-level Control Unit via DRIVE-CLiQ. The
● An external 24 VDC supply is required to operate liquid-cooled Power Modules.
● The correct line reactor must be connected in series to achieve category C3 EMC
The volumetric flow of the coolant is monitored by the software. If the volumetric flow is
continuously lower than the setpoint, an alarm (A5005) is first displayed. If this alarm
remains active continually for the next 5 minutes, a fault message (F30047) is activated
which shuts down the unit.
The fans for the internal electronic circuitry are only switched on when required.
The fans are switched on and off as a function of several factors (e.g. heat sink temperature,
ambient temperature, output current, duty cycle, ...) which means that fan operating cycles
cannot be calculated directly.
