Manufactured by Load Controls Inc.

The compact PMP-25 digital load control provides an efficient low cost solution to pump motor protection or the prevention of damage to pumps motors caused by overload, jamming, loss of load or pump dry running. The rugged polycarbonate sealed enclosure may be mounted in many configurations including door, wall or cabinet. This pump monitor for pump protection is easy to install and displays true power on a large easy to read bright red digital LED display. Both high and low power trip relays with adjustable start up delay and individual trip timers are standard features. The low power trip, when used to detect cavitation or loss of prime, is up to ten times more sensitive that of conventional undercurrent relays. The high power trip is provided for the detection of problems such overloads, jammed impellers, bad bearings or blocked outlets The PMP25 pump monitor is suitable for single phase or three phase pump protection, detecting cavitation or loss of prime with pumps of all types, including seal-less or magnetic drive, centrifugal, positive displacement, process and sewage pumps. 

Variable Frequency Power (UPC + "V" SERIES)

Voltage and current transformers do not work at low or high frequencies. In this case, waveforms on both the input and output of a drive, are distorted and will cause gross errors in the measurement of power. Where variable frequency or inverter drives are fitted, the PMP-25 V Series Digital Pump Load Control should be used in conjunction with the unique Universal Power Cell designed for this purpose. The UPC is fitted with "Hall Effect" sensors that are not affected by odd wave shapes or frequencies.
