The PMP Series of micro-controller based Single-Phase Proportional Control SSRs are designed to offer precise control of the power delivered to a resistive load in a compact 22.5mm housing, with ratings from 25 up to 90 Amps at 90 to 600 VAC. PMP Series solid state relays can vary the output load power proportionally to an analog control input from 0 to 100%. This can be achieved by two different methods: Phase Angle control and Burst Fire control (with Distributive Zero Cross). The control method to be used can be selected on the unit by means of a selector switch located on top of the SSR. This selector switch also allows to select the type of analog signal to be used at the control input. The available input types are: 0- 5 VDC, 0-10 VDC, and 4-20 mA. PMP Series Proportional SSRs are ideal for lamp dimming and resistive heating control, among other type of applications requiring proportional control.
