PM330 Power Module, degree of protection IP20, frame size GX

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⁾.

If required, various high-performance dv/dt filters or a Braking Module can be connected. A corresponding DC link connection is available as standard.

All available system components are coordinated exactly with the PM330 Power Modules. This enables the implementation of reliable, safe, customized control cabinet solutions. All connections can easily be accessed from the front. The internal modules are very easily accessible.

Exceptional requirements concerning motor cable lengths can be easily implemented via output reactors. Series connections are permissible here.

The PM330 Power Modules are designed for connection to grounded TN/TT systems and non-grounded IT systems. 690 V line supplies with grounded line conductor are not permitted.

The CU230P‑2 Control Unit intended for PM330 Power Modules does not have special Safety Integrated functions. Safety functions can be implemented by means of external switching devices.

¹⁾ To comply with Category C2, shielded cables must also be used between the converter and motor with a maximum permissible cable length of 150 m (492 ft). Long cables can be used if output reactors and output filters are connected (see section Load-side power components).
