DELSTAR CONVERTER
MODULE 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. The starting regimen is not disturbed. This module is recommended for applications where load changes are not too fast. Suitable for any capacity motor by using appropriate Current Transformer(C.T)and calibrating the same for the appropriate capacity of the Motor(carried out at the Factory before despatch).

Given
below is a table showing the scope for saving energy for the motors
of different capacity ranges at different loads. The actual values
will vary from motor to motor and the savings can be higher or lower
depending upon electrical parameters and mechanical condition of the
motor.
ENERGY SAVING DATA FOR A 5 HP MOTOR In tests conducted on a 5 HP motor with a full load current of 7.9 amps the savings on no load is 65.3%, reduction in operating current is upto 79.4%, reduction in demand 78.8% and improvement in power factor 60%. Please refer to the table given below :
Similarly the saving on a 12.5 H.P. motor on no Load is 540 Watts AS AGAINST 740 Watts(73% savings). DIFFERENT OPTIONS AVAILABLE ARE a) Start in star and changeover to Delta and then operate in Star or delta, based on load. b) Start in Delta and changeover to star when the load is less than 50% (for motors with high starting torque requirement). c) Changeover from Star to Delta based on current instead of time.(It is likely that the Motor is started with different loads at different times and the timing set in the timer may not be always suitable for these differing loads. It may be too high or too small. Hence this facility will take care of this type of problem). Supply Voltage Required: 230 V or 415 V 50 Hz. UNITERRUPTED AND HIGHLY SATISFACTORY FUNCTIONING GUARANTEED. TATA ENERGY RESEARCH INSTITUTE, BANGALORE has evaluated the product under actual working conditions and have certified the product. Being recommended by Energy Cell of CONFEDERATION OF INDIAN INDUSTRIES and a number of Energy consultants and Energy Auditors. Different Models are available - Features\Facilities are given below
NOTES : SM2D and EM1D are same as SM2 and EM1 but provided with Digital Indication for Operating Current, respectively. Similarly, suffix T indicates that the unit is provided with an Hour Counter to log the number of hours of operation in either in Star or Delta. EM1P and EM2P are sealed models corresponding to the respective models with specifications which are identical. However all optional features cannot be provided. The size of EM1P is 125*80*60 mm and EM2P is 100*80*50 mm. These are suitable for use in various areas where there is constraint in space, highly corrosive and explosion prone areas. All models are provided with LED Indications for Power On, Star(energy saving), Delta, and all protections. Contactor life can be extended by an addition accessory supplied as optional.
