Sun Electrical Rectifiers are fitted with AC Voltmeter, DC Voltmeter and DC Ammeter.
Sun Electrical Rectifiers are fitted with high quality and over rated rectifier diodes to withstand overloads and momentary surges. High quality auto transformers are employed to maintain low losses thus achieving higher efficiency and power savings.
Sun Electrical electroplating rectifiers consists of an auto variable transformer, one step-down transformer, and bridge rectifier and protection system. Input AC voltage is fed to input side of variable Auto transformer. The output of auto variable transformer is connected to input side of step down transformer .Output of step-down transformer is connected to bridge rectifier to obtain required DC Voltages. Bus bars and all transformer windings are with higher grade electrolytic copper of 99.99 % purity.
Protection systems employed in Sun Electrical electroplating rectifiers consists of HRC fuses. MCB / MCCB. The rectifiers are also having various additional / optional features and protections like auto zero correction, auto trip OFF, single phasing prevention, electronic overload Protection, high input Voltage trip OFF, at high system temperature , programmable switching ON and switching OFF of the rectifier in selected timings etc. and as required by the customer.
