AMETEK ZF2-480-70-C Power Control System Controller

AMETEK ZF2-480-70-C Power Control System Controller is a two-leg, back-to-back SCR power controller in the AMETEK HDR ZF2 family that regulates AC power to a load by zero-firing the SCRs, a configuration commonly used for precise control of three-phase loads in industrial environments. Model ZF2-480-70-C denotes 480 VAC operation and a 70 A rating, aligned with the ZF2 series' selectable voltages (120, 240, 400, 480, 575 VAC) and current options (15, 25, 40, 70 A). These devices are used to regulate power to industrial loads such as heating elements or other resistive/inductive loads in three-phase power systems, delivering controlled power while protecting circuitry. The ZF2 family operates as SCR-based power controllers, employing a zero-fired control method that enables precise power regulation in demanding plant environments. Variants such as ZF2-C support 4-20 mA control inputs, a common industrial signaling standard for remotely commanded power control.
