Vedika Instruments 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 aluminum-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.

 Basics of SCR Power Regulator

Semiconductor power devices

Triggering Card: Control circuit normally referred to as the firing circuit

Heat Sink: Dissipate the heat generated from the semiconductor devices

Protective circuits (fuses and transient suppressors)

Cooling- Natural cool or forced air cool using high speed noiseless air circulating fans   

Input and output terminals- Clip-on type heavy duty connectors or copper bus bars

Entire assembly is mounted on sleek and easy to install anodized aluminum enclosure with safety ABS removable covers
