A linear phase-angle controller suitable for switching inductive loads accepts a wide range of inputs, including ranging from 0 to 135 Ohms, 4 to 20 mA, 0 to 5 Vdc, or 0 to 10 Vdc, as well as potentiometer and PWM signals. Load currents range from 40 mA to 100A ac. Load voltages up to 660 Vac are available. Standard features include line voltage compensation, soft start, transient overvoltage protection, adjustable voltage limiting, and an LED status indicator. The controller, which allows for 50- to 60-Hz operation, is manufactured as one assembly that consists of an engineered phase controller, solid-state relay, and heat sink. A DIN rail mounting is available on most models.
