Digital Dc Drive By Crpn Control System (Pvt) Ltd.

Enhance performance by advance technique such as:

Phase Locked Loop (PLL) ensure flawless synchronization despite polluted mains and compensates for mains voltage variation

C.T. Operated field protection to make a precise tripping

Train of firing pulses by using ferrite core transformers ensure reliable triggering of thyristor

Adaptive regular gives optimum response under varying load conditions

Current amplifier has facility for external current reference

A trip relay with electrical latch provides interlock with motor

The control card incorporated LED monitoring to assist in rapid fault diagnosis

Designed for larger power supply variations

To eliminate the Re-Tuning of control card, adjustments and terminal row for external connection broght to a separate card

Flat ribbon cable eliminates cumbersome conventional wiring to facilitate quick replacement

Linear acceleration / deceleration ramp provides independent adjustment of an acceleration and deceleration rates over a range of 2-30 Sec. If not required can be linked out
