Softstarters – DM4 and DS4 Ranges

DM4 softstarters enable the electronic starting and coasting of three-phase asynchronous motors from 7.5kW to 900kW (400V).

There are two connection types: Standard connection for 7.5–500kW at 400V, and "In-Delta" connection for 11–900 kW at 400V.DM4-340 softstarters are factory-set for standard applications, which can be selected via a rotary switch.

An optional keypad with text display allows the individual parameters to be displayed and set. The keypad is required if the digital and analogue inputs/outputs of the softstarter are to be reprogrammed.

DS4 – Versatile starting
Combining compactness with versatility, the DS4 range of semiconductor contactors and softstarters offers condition signalling, a wide range of voltage inputs in one unit and compliance with the latest international safety standards.

The DS4 is ideal for heating and lighting as well as motor control applications.

Softstarter applications include:
Pump and fan drives.
Conveyor belts.
Compressors.
Circular and ribbon saws.
Agitators, mixers, mills and crushers.
