Three phase thyristor controller

Powerstax has introduced its DTC 352 Dual Control Channel Three Phase Thyristor Controller suitable for use in electro-chemical processes and control of motors, heaters and traction equipment.

The DTC 352 is a claimed to allow closed loop control of both output voltage and current on either primary or secondary thyristors.Its robust control circuit allows it to operate from a range of AC power supplies including generators.

The device can be used either as an open loop controller or as a two-channel closed loop controller to control two parameters simultaneously.

Key features of the Powerstax DTC 352 Thyristor Controller include; primary or secondary control available, auto-adjust for 50 or 60Hz supply frequency, Logic Control for ON and OFF, power on and ‘Logic’ on soft-start with adjustable delay, selection of supply voltages and span and zero adjust for a range of different inputs.

The DTC 352 has an operating temperature range of 0 to 50°C and isolation of 2500Vrms between input and output. An auxiliary 10V output is provided for manual control and LEDs provide indication of power on, Logic Control status, phase loss and when either channel reaches its limit setting.
