Crydom / Sensata PMP Micro-Controller Based Single-Phase Proportional Control Solid State Relays are designed to offer precise control of the power delivered to a resistive load in a compact 22.5mm housing. The PMP components feature ratings from 25A up to 90A at 90VAC to 600VAC. 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 the user to select the type of analog signal to be used at the control input. The available input types are 0 to 5VDC, 0 to 10VDC, and 4mA to 20mA. Crydom / Sensata PMP Series Proportional SSRs are ideal for lamp dimming and resistive heating control, among other types of applications requiring proportional control.
