Thyristor Power regulator

RADIX brings you a full range of Thyristor (SCR) Power Regulators, which are compact in size, robust in design and easy to maintain. These Power Regulators control power to the resistive or inductive heating loads which can be single-phase, two-phase or three-phase. They can switch load power extremely fast providing the means to respond rapidly to command changes, load changes & power supply changes. This feature allows the control of fast responding loads and eliminates the negative effects of variations in load or supply voltages that can occur with other types of control. Radix power regulators comprise of triggering card, suitably rated back-to-back connected SCR modules mounted on special aluminium-alloy heat sink duly isolated electrically . In a typical application it consist of a controller and sensing element (Temperature sensor connected to heater or job) in loop with a safety controller.

The cooling is either natural cooling or forced air cooling using high speed noiseless air circulating fan(s). Input and output terminals are clip-on type heavy duty connectors or copper bus bars. For safety, suitably rated semiconductor fuses and thermal cut-out is provided. The entire assembly is mounted on the very sleek and easy to install Anodized Aluminium enclosure with safety ABS removable covers.
