Avatar Instruments

Avatar Instruments produces reliable, rugged SCR Controllers. Their experienced engineering staff is constantly making improvements to provide safe, straightforward solutions to industrial electric heater control.  All Avatar products are tested and designed to work in real-world environments, including industrial power lines, at temperatures of 122° F. Our standard product line is UL508 and cUL listed to ensure safety.



Avatar A1PSingle Phase Power Controller

The A1P is a proportional, infinitely variable power controller capable of delivering 0-97% of the applied line voltage to the directly connected electric heaters.

Avatar Single Phase Power Controllers



Avatar A3P3 Phase SCR Power Controller

The A3P is a proportional, infinitely variable power controller capable of delivering 0-97% of the
applied line voltage to directly connected electric heaters. It will not control transformers or
motors. This is accomplished by phase angle firing three SCR's (one per phase). Modular construction allows for simple and solderless field serviceability.

AxZ Series – Single Phase / 2 Leg – 3 Phase / 3 Leg – 6 Phase SCRs

Avatar AxZThe A1Z is a proportional, zero voltage switched, single phase power controller capable
of delivering 0-99% of the applied line voltage to directly connected electric heaters. It
will not control tungsten lamps, transformers or motors.  The standard input signal (4-20mA) is applied to the blue input terminal block, processed and fed to optical couplers. The output of each opto coupler controls its respective SCR.

Avatar BB Series Transformer Drivers

The Avatar Instruments B series controls are phase angle fired controllers designed to proportionately regulate the voltage to transformer coupled resistive heaters. Many special high temperature, low voltage heating elements such as tungsten, graphite, silicon carbide and molybdenum can only be used safely on voltages far less than industrial power lines. These low voltage elements are connected to the low voltage or secondary side of a transformer for maximum control and safety. The Avatar B series power controller is connected to the primary or high voltage side of the transformer. This provides smooth, proportional control of the heaters, while maximizing the sine wave of the power line (or power factor).

Avatar CZLow cost SSR Zero Voltage switched power controllers

The Avatar C1Z Series units are Zero Voltage switched, single or three phase fused power controls used to replace mercury or mechanical relays. there are no parts to mechanically wear out: Millions of operations can occur without failure. High/fast duty cycle will not damage the C1Z series controllers. No arcing problems like with mechanical relays. Dust and Dirt will not cause long term reliability issues.

Avatar 2CPMulti-Zone Phase Angle Fired SCR Power Controls


The Avatar Series CP Multi-zone SCR Power Control provides individual control of up to six single phase heaters/zones in one rugged, space saving device. Each zone command signal independent of the others. No phase rotation or load balancing restrictions. Standard Control Signal 4-20 mA, no Signal Transformer needed. All units come as assembled units. Fuses are optional.
