The CSR chip is a combined thick film triac and phase angle firing circuit built into one package with an isolated tab heatsink. The two types available (A & B) are different sizes for mounting purposes.

PHASE ANGLE REGULATORS QLC This power regulator is pre-set to give three positions of control (low, medium, and high) and an off position. The QLC is designed to withstand four times full load current on switch on. united automation ltd Call On: 01704 516500

BURST FIRING REGULATORS & PHASE ANGLE FIRING CIRCUITS X10542ZVT-25 This is a high power version of the ZVT temperature controller complete with an integral heatsink and semiconductor fusing. united automation ltd Call On: 01704 516500

This power module features an integral triac to enable control of resistive and inductive loads up to 25A, when fixed to a suitable heatsink. The module can be used on line voltages from 25v to 230v,simply by selecting the type of auxiliary transformer used.

BURST FIRE / DUAL MODE FIRING CIRCUITS & POWER MODULES FC11BL This trigger module provides control of thyristors in virtually all single-phase or phase to phase resistive load applications. The firing circuit is designed to give a variable on/off output ratio, proportional to a wide range of common voltage or current control signals. The module is not restricted for just 230v or 400v applications as the auxiliary transformer can be selected to suit any line voltage up to 440v. This microprocessor based temperature control module incorporates most of the characteristics of a three-phase...

X10245STOM-2 This microprocessor based trigger module is capable of driving most power thyristors and thyristor pairs. A wide range of common voltage or current control signals is accepted by the module plus manual control via a potentiometer. The module will operate in either phase-angle or burst-fire mode. It can be set up to soft-start in phase-angle mode, then switch over to burst-fire mode once a pre-set output level is reached. The unit is not restricted to 230v or 400v applications as the auxiliary transformer can be selected to suit any line voltage up to 440v.

SPECIALIST POWER PRODUCTS X10559RMS/DC-FB The RMS to DC converter board is a microprocessor based closed loop controller which can be used with any phase angle controller having a 0-5v input signal. Its uses therefore extend to many voltage and current limiting applications incorporating current transformers or shunts. Features • Constant voltage or current regulation • Variable gain control • High speed feedback response • Selectable average or true RMS readings • Supports FC36M and other firing circuits • Optional DIN rail mounting enclosure united automation ltd Call On: 01704 516500
