DC Drives

Gururaj Engineers offers a DC Drive, GE 157. It is a very stable compact DC drive, which can be used for up to 2 hp DC motors. This can accept different types of inputs like start, stop, inch (optically isolated) and 0-5 V, 0-10 V, 4-20 mA as reference. This compact thyristor controller DC drive can work with normal conventional DC motor with field winding as well as permanent magnet DC motors. The speed of a DC motor is directly proportional to the armature voltage with fixed field excitation. Features: LED indication for quick fault finding/status indication; soft start; field fail protection; armature current limit/trip; fuse protection; 1/2 hp selection through link; normal/PMDC motor selection through one link; and Run (Start) Stop. Specifications - range: 0.14-2 hp; input: start, stop, inch, digital commands; ref: analogue 0-5/0-10 V: 0-20, 4-20 mA (optional); supply: 230 V to ±10% 50 Hz; output: fixed field 200-220 V DC, armature: variable 0-220 V DC; field current: 1 A maximum; armature current: 8 A maximum; cooling: natural air cooling; dimensions (W x H x D): 180 x 230 x 100 mm; and mounting: base plate mounting (inside panel). Applications: winders, packaging machines, textile machines, pharmaceuticals, etc.
