AC/DC SPEED DRIVERS

DC DRIVE :
Uni– Bi directional speed drives, rectification by full SCR (Thyristor) bridge, and control by micro-processor,
Function : Variable speed, inching, and braking.
Maintenance free, soft-start, robust, over current protection, both scalar and vector operation i.e with/without speed feedback.

AC VARIABLE FREQUECY SPEED DRIVE :
These drive are controlled by micro-controller, having embedded code, for logical and technical function.
Function : variable speed bi-directional, inching, soft start and barking. Scalar and vector operation possible .
V/f ratio is maintain on all torque conditions. The construction is robust for continuous operation, and are maintenance free.

Speed feed-back : A easily mountable pulse generator
Over-Current, protection, Carrier frequency 1-5 Khz,
Switching element : High performance IGBT’s
Interface : LCD display.

SOFT-STARTER FOR INDUCTION MOTOR:
A micro-controller based system controlling SCR bridge for three phase AC, and phase angle are varied, to control starting current, and different curves are in controller, and are utilize by user, for operation of induction motors. Different Current curve are selectable by key board on front bezel of panel. This equipment not only operate motor from equivalent generator Proportion to running current), so running cost of motor is reasonable.
