Moeller Unveils New Intelligent Solution to Softstarting

[picture of DM4 softstarter] Leading automation and switchgear specialist, Moeller, has released a new range of softstarters to complement its comprehensive industrial automation portfolio.

The new DM4 softstarters offer easy set up, integral motor protection and network connectivity for monitoring and control for motors rated from 7.5 to 900kW. This innovative softstarter range complements Moeller's state-of-the-art DF5 and DV5 drives, PLCs and other automation products, enabling the company to provide a total industrial automation solution.

With the DM4 softstarter range all internal parameters may be set for a particular application by simply using a screwdriver to turn the setting selector for any of ten typical applications. Once the desired application is selected, the softstarter automatically sets the parameters for the application. Additionally, every starting parameter can be individually adapted via the optional keypad. The devices' in delta function allows up grading to higher motor ratings. The units are ideal for a wide range of applications from pump and conveyor motors, to, when functioning as a voltage regulator, industrial heating and furnaces.

The softstarters are easy to integrate into the bus network via built-in bus interfaces for Suconet K, Profibus DP and INTERBUS. An RS232 interface supports serial communication for configuration via a PC.

The devices' integral motor protection function includes current limitation for starting and an alarm threshold for the uninterrupted current, as well as supporting direct motor thermistor input into the drive. Undercurrent monitoring enables detection of belt failure. Energy saving is achieved through the DM4's cos theta function, which reduces the motor's voltage requirement when off load.

The DM4 range complies with IEC/EN60-947-4-2 and is ingress protected to IP20.
