Avatar Instrument A1Z-48-30 Power Controller Module

The Avatar Instruments A1Z-48-30 is a single-phase SCR power controller designed to regulate power to resistive loads from a 480 VAC supply. It provides a 30 A load rating and accepts a 4-20 mA control input, enabling a standard industrial current loop to set output. The device operates in phase-angle firing mode, delivering controlled portions of the input voltage to the connected load, and includes no auxiliary output. As part of Avatar’s A1Z-series SCR power controllers, the A1Z-48-30 is intended for applications requiring precise, real-time control of electric heaters, ovens, and other resistive elements that run on 480 VAC. Its straightforward, one-channel control makes it suitable for integration into control panels where a dedicated high-voltage power controller is needed to modulate heating loads. With its 480 V input rating and 30 A current capability, it can handle common industrial heating loads, supporting stable operation and repeatable performance in temperature-control or process-conditioning setups.
