Phase Sequence Corrector

Elite automatic phase sequence corrector is designed to supply an industrial and domestic for three phase applications.

Ranges: Automatic Phase Sequence Corrector – 9 A – 400 A

ELITE PSC always gives output 3 phase supply in the right sequence and maintains 120° between phases, even if the input sequence is interchanged. Normally, for any 3 Phase Machines (or) Equipments like AC, UPS, Lifts and Motors, 3 Phase incoming supply has to be given in the right sequence (R, Y, B).

The Phase angle of 120° between the phases R, Y, B is to be maintained to run 3 phases Motors. If the sequence is changed instead of R, Y, B to Y, R, B the motor tends to rotate in the reverse direction. In case of 3 phase UPS, due to wrong sequence, the input supply will be cut and it starts working in the battery mode resulting in draining of battery.

If the sequence is changed for loads like 3 phase AC, UPS and Lifts, they will stop functioning due to the inbuilt sequence protection and only when the input sequence is corrected manually, they start functioning. ELITE Automatic Phase Sequence Corrector always gives an output 3 phase supply in the right sequence and maintains 120° between phases, even if the input sequence is interchanged. Thus all the 3 phase equipments continue to run irrespective of the change in input phase sequence.

Operating functions

• Whenever three phase input supply is given to ELITE – PSC, it checks whether all the 3 phase are alive initially
• If all the three phases are detected by the Single Phase Preventer (SPP), then it checks and selects the RIGHT SEQUENCE to give always the desired output.
• In the event of phase failure, ELITE – PSC disconnects the load and protects 3 phase equipments from damages.

• Fully Automatic
• Output In The Right Sequence(R,Y,B)
• Voltage Imbalance Protection Between Phases
• Auto / Manual Mode
• Single Phase Prevention
• High / Low Voltage Protection
