Description

PAC2 Phase Angle Firing Module (25A 6kW AC Control)

The PAC2 from United Automation is a compact, high-power, full-wave AC phase-angle controller designed for precise power regulation in demanding industrial and commercial equipment. Capable of controlling up to 6kW (25A) at 230V, the PAC2 modulates the AC phase angle to deliver accurate, proportional power to the load.

Built using surface-mount technology with low thermal impedance and high electrical isolation, the PAC2 offers excellent reliability and flexibility for equipment designers. An internal snubber network helps eliminate nuisance switching, ensuring stable operation with inductive and resistive loads.
