Gururaj Engineers Presents GE 157, A very stable compact DC DRIVE, which can be used upto 2 HP DC motor. This can accept different types of inputs like START, STOP, INCH (OPTICALLY ISOLATED) & 0-5V, 0-10V,4-20mA as reference.

This compact thyristor controller D.C Drive can work with normal conventional DC motor with field winding as well as permanent magnet DC motors. The speed of DC motor is directly proportional to the armature voltage with fixed field excitation. To vary the speed of a shunt wound seperately excited/PMDC motor the armature voltage has to be varied from zero to the rated voltage of the armature.

• LED indication for quick fault finding / status indication
• Soft start
• Field fail protection
• Armature current limit / Trip
• Fuse Protection
• 1 hp/ 2 hp selection through link
• Normal / PMDC motor selection through 1 link
• RUN (start) stop, inch selection through optical isolator so that command from PLC / external source can be given to the drive

Specification:

Range 0.14 HP to 2 HP Input Start, Stop, Inch, Digital commands Ref Analog 0-5 V / 0-10 V : 0-20 mA, 4-20 mA (Optional) Supply 230 V ˜± 10% 50 Hz Output Field fixed 200-220 V DC, Armature - Variable 0-220 V DC< Field Cureent 1 A Max Armature Current 8 A Max Cooling Natural air Cooling Dimensions W : 180mm X H : 230 mm X D : 100mm Mounting Base plate mounting (Inside Panel)
