G120P-PM330

160 kW to 630 kW

PM330 Power Modules have been specially developed for simple applications, such as driving pumps, fans and compressors with speed-controlled increasing load characteristics.

PM330 Power Modules meet the very high energy efficiency requirements particularly well, especially in this area of application, because they offer the best possible energy utilization in all operating ranges. This is achieved by the very high efficiency verified according to EN 50598, various energy-saving functions, and the automatic pulse frequency adjustment.

To reduce emissions, the PM330 Power Modules are equipped with a radio interference suppression filter as standard (in accordance with the limit values defined in Category C3). Through the use of an external line filter, the PM330 Power Modules also comply with the limits for use in the first environment (Category C2) as specified in EN 61800‑3‑1).

The PM330 Power Modules have the following connections and interfaces:

  • PM‑IF interface to connect the PM330 Power Module to the Control Unit. The PM330 Power Module also supplies power to the Control Unit using an integrated power supply.
  • Motor connection and line supply connection via screw studs
  • DC-link connection for Braking Module and dv/dt filter
  • PE (protective earth) connections
  • Terminal block X9
    • Input for external 24 V DC supply
    • Input for external alarm/fault
    • Input for EMERGENCY OFF / EMERGENCY STOP
    • Output for 24 V DC (output current max. 250 mA)
    • Control of the main contactor
    • Feedback message "DC link charged"
  • Terminal block X41 1)
    • Dual-channel STO activation
    • Feedback switch-off signal path
    • Enabling STO via combination/assembly on switch S41

1) Available for Power Modules as from function release FS 04

PM330 Power Modules communicate with the Control Unit via the PM-IF interface.

For the STO and SS1 safety functions, we recommend the use of SIRIUS 3SK1 safety relays with relay outputs and 24 V supply voltage. The safety relays can be directly supplied with voltage by the Power Module. This enables the very simple implementation of the STO safety function.

  • STO: 3SK1111-2AB30
  • SS1: 3SK1121-2CB42
