Thyristors come in wide range of amperages


System Integration

THV thyristor is now offered in a wider range of amperages and offer programmable phase control or zero-cross control.

South Bend, IN —THV compact microprocessor-based SCR power controller from RKC Instrument has added a full line of amperages. Reportedly designed to provide higher performance at lower cost, the devices are now available in 20, 30, 45, 80, and 100 A. THV features programming keys and a digital display on the front. It responds quickly to input changes and offers programmable phase control or zero-cross control. Set values and input signals can be checked and monitored using the front digital display keys or through an external setting unit such as a variable resistor.
Standard functions include gradient setting, ramp-up and ramp-down, and high/low output limiters. Also included are three types of output modes and base-up setting (output bias). THV operates at 100 to 240 V ac and automatically selects power supply frequency of 50 or 60 Hz. Series carries UL, cUL, and CAS approvals.
