Liquid-cooled Power Modules in blocksize format: Frame sizes FSD, FSE and FSF
Liquid-cooled PM340 Power Modules transfer most of their heat losses to the cooling liquid through the integrated stainless steel heat exchanger. As a result, they can be installed in control cabinets with high degrees of protection. They do not utilize high-maintenance filter mats or ventilation grilles. The units are designed for vertical mounting.
Liquid-cooled PM340 Power Modules have the following interfaces as standard:
- 1 power connection
- 1 PM IF interface for connection of the PM340 Power Module and CU310/SIMOTION D410 Control Unit or CUA31/CUA32 Control Unit Adapter. The PM340 Power Module also supplies power to the Control Unit or Control Unit Adapter by means of an integrated power pack
- 1 connection for external braking resistor (DCP/R1 and R2)
- 1 motor connection
- 1 control circuit for the Safe Brake Relay for controlling a holding brake
- 2 PE (protective earth) connections
- 2 coolant connections
Liquid-cooled PM340 Power Modules are available only without integrated line filter and can be connected to grounded TN/TT systems and non-grounded IT systems. The integrated Braking Unit (Braking Chopper) is rated with the capability to permanently energize the braking resistor. The temperature of the external braking resistor must be monitored (i.e. thermostatic switch) to provide protection against thermal overloading.
The scope of supply of the Power Modules includes:
- 2 seals for coolant connections
- 2 protective caps for coolant connections
