DRMS SERIES 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 PRODUCT SELECTION Part Number Functions Forward/Reverse, Overload Protection DRMS48D91 Forward/Reverse, Overload Protection, Soft Start/Stop DRMS48D92 Forward/Reverse, Overload Protection, Soft Start/Stop, Mains Isolating Relay DRMS48D93 SPECIFICATIONS (1) Output Description DRMS48D9x 200-480 10% Operating Voltage L1/L2/L3 Vrms 50/60, automatic detection Nominal Frequency Hz 1500 Peak Reverse Voltage Vpk 550 Overvoltage Limiting Vrms Page 1 www.sensata.com Copyright 2018 Sensata Technologies, Inc.0.5 Maximum Off-State Leakage Current Rated Voltage mArms (2) 9 Load Current, AC51 Arms 7.6 Load Current, AC53a: 6-2: 10-30 IEC/EN (2) 60947-4-2 Arms 4 Maximum Motor Power kW 400 VAC Minimum Motor Power W 25 Maximum Surge Current Apk t = 20 msec 200 Load Limit Integral Asec t = 10 msec 200 Starting Voltage 30-80% 1-10 Start / deceleration ramp sec 250 Switchover Delay Time msec 25 A gG / gL Max.
