Electroplating Rectifiers

Servomax offers a wide range of rectifiers for plating and anodising applications up to 3000 A DC capacities. The company offers all types of rectifiers commonly required for electroplating and metal finishing applications. Electroplating rectifiers are available in automatic and manual models. In automatic model solid state electronic circuitry with motorised auto transformer is implemented. In manual model a tap selector switch is used to select the required current and voltages. Designed with high quality control and using best quality raw materials with state-of-the-art technologies to save power, Servomax rectifiers are available from minimum voltage of 1 V, 1 A and up to 30 V DC and 3000 A current. These rectifiers are fitted with AC and DC voltmeters and DC ammeter, and high quality, 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. Electroplating rectifiers consist of an auto variable transformer, one step-down transformer, 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 consist of HRC fuses, MCB/MCCB. Additional/optional features and protections include 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.
