PA1 Single Phase Power Controller

The PA1 Single Phase Power Controller series from Halmar Robicon comprises single-phase, SCR-based power controllers used to regulate AC power delivery to resistive loads. These units use phase-angle firing control, typically responding to a 2-10 VDC analog input signal, to provide precise modulation of power. Common applications include industrial heating such as electric annealing furnaces and other high-power thermal processing equipment found in metal processing plants.

The series spans a range of voltage and current ratings, including 480 VAC models at various amperages. Alongside the complete power controller units, the series also includes PA1 firing circuit control cards and modules used within these controllers.

Products in This Series

• Power controllers — single-phase phase/amp SCR power control units across multiple voltage and current ratings.
• Firing circuits — control cards and modules that support the firing control function.
