DELSTAR CONVERTER MODULE is an electronic system to be interfaced with the existing\ STAR DELTA STARTER. When the load on the motor is less than 50% of full load. It switches the motor to operate in STAR to SAVE ENERGY. When the load increases beyond 50%, it automatically switches the motor to operate in DELTA. This module is recommended for applications where load changes are not more than 120 times/hour. This can be used with any capacity motor by choosing appropriate current transformers (C.Ts) and setting the current level using the potentiometer built in. This setting is generally done in factory before dispatch.

ADVANTAGES

• Very good scope for saving energy (Payback period less than one year in majority cases)

• Reduction in KVA, contributing to reduction in maximum demand.

• Improvement in power factor.

• Motor runs cooler leading to increased motor life.

OPTIONS AVAILABLE

• Motors coupled to HIGH INERTIA LOADS require higher capacity motors to meet the starting current requirements. These motors work at low loads, once starting is over. In these cases motors can be started in Delta and then run in star to save considerable amount of energy. If motors are fitted with DOL starter only, it will be worthwhile to fit a star delta starter along with the module to save energy.
   

• LCD indication for operating Current.
   

• Time Totaliser to indicate number of hours of operation (in Star or Delta). Supply Voltage required : 220 Volts (Standard) or 415 Volts (optional).

UNINTERRUPTED AND HIGHLY SATISFACTORY WORKING GUARANTEED

More than 400 units are working in different categories/types of industrial establishments very satisfactorily.
