PMP Series

The Sensata Crydom PMP Series of Proportional Control Solid State Relays are designed to deliver precise power control in various industrial applications. These relays are ideal for lamp dimming, resistive heating, and other uses requiring accurate power management. The PMP Series offers output ratings of up to 90 Amps at 600 VAC, providing robust performance in demanding environments. 

This series includes several models, such as the PMP2425W, PMP2450W, and PMP2490W, with operating voltages ranging from 90-280 VAC to 420-600 VAC. These relays can vary output load power in direct proportion to an analogue control input, offering 0-100% control through either Phase Angle or Burst Fire control modes. The control mode is easily selectable through a switch located on the relay, and users can choose between 0-5 VDC, 0-10 VDC, or 4-20 mA control inputs. 

A key feature of the PMP Series is its adaptability to both 50 Hz and 60 Hz frequencies, allowing it to function seamlessly in diverse electrical systems. Additionally, the 4-20 mA input option eliminates the need for an auxiliary power supply, simplifying installation and reducing costs. The relays also feature a multifunction LED status indicator, providing clear visual feedback on the system’s operational status, including error conditions and overtemperature. 

The relays are housed in a compact 22.5mm enclosure, with an aluminium baseplate and nickel-plated finish, ensuring durability and effective heat dissipation. The “elevator” screw terminal design further enhances ease of installation and secure wiring connections. 

Overall, the Sensata Crydom PMP Series provides reliable and efficient proportional control, making them an excellent choice for industrial control applications that demand high precision and robust performance.
