Industrial thyristor controlled transformer rectifiers

Powerstax has released its Drake TR Series of Industrial Thyristor Controlled Transformer Rectifiers. Available with outputs up to 750kVA this range of Transformer Rectifiers uses analogue or digitally controlled thyristors to achieve the required voltage and current profile.

Typical applications for the Drake TR series include water treatment, electrochlorination, surface finishing, cathodic protection and anti-fouling, electrophoretic processes, aircraft ground support, marine and offshore and engine starting.

Key design features include thyristor control, 415VAC 3-Phase input, <1% output stability, <5% output ripple, Short circuit protection, Integral fan cooling, Remote control and monitoring options, top or bottom cable entry options, analogue or digital voltage andcurrent display.

Standard products are available over the range 15V at 1500A, 30V at 2000A, 60V at 3000A, 75V at 1000A, 150V at 1200 and 400V at 500A. Output voltage can be adjusted from 0V to full voltage when in voltage control mode and output current can be adjusted from 0A to full current when in current control mode.
