DIN RAIL MOUNT HYBRID MOTOR STARTERS

DRMS Series Hybrid Motor Starters are intelligent and convenient solutions for controlling 3-phase asynchronous motors. These compact devices can provide up
to 6 functions in the same unit: Forward/Reverse, Soft Start/Soft Stop, Motor Overload Protection, and Mains Isolating Relay.
Motor overload detection is based on a thermal load curve. The relays are de-energized when an overload condition is present, ensuring a long service life.

Features

• 3-phase motors reversing up to 4 kW

• 2-phase soft start/stop

• Up to 4 dials for setting of starting torque, deceleration torque, soft start/
stop, and rated motor current

• 4 LEDs for status indication

• Galvanic separated 24 VDC inputs for forward and reverse control

• Reset button on front, with connection for external reset

• Relay indicator output for operation

• Hybrid relay combines benefits of electromechanical relay technology with
non-wearing semiconductor technology

• High reliability by temperature monitoring of semiconductors

Applications

• Reversing operation for door and gate controls, bridge drives and lifting

applications with monitoring of blockage

• Conveyor systems with monitoring of blockage

• Actuating drives in process controls with blockage monitoring

GENERAL NOTES

(1)

All parameters at 25°C unless otherwise specified.

(2)

To achieve maximum ratings there must be a minimum spacing of 0.9 in (22mm) between the devices in free air (see derating curves).

(3)

For reliable operation the 24 VDC auxiliary power supply needs to be fully stable during the entire operation of the device. Removing this volt-

age while the output is under load could cause permanent damage to the device.

Additional Notes

• This device is intended for use on supply systems with a maximum voltage from phase to ground of 300 V (e.g. for a three phase-four wire system
277/480 V or on a three phase-three wire systems of 240 V), rated impulse withstand voltage of max. 4 kV.

• Suitable for use on a circuit capable of delivering not more than 5000 rms symmetrical Amperes, 480 Volts maximum when protected by class CC,
J or RK5 fuse rated maximum 20 A.

• For use in pollution degree 2 Environment or equivalent.

• The control circuits of this device shall be supplied by an isolated 24 VDC power supply which output is protected with a fuse rated max. 4 Adc.
