Pump Protection Relay – DPP3

$54.63

Advance pump protection relay to safeguard against damage to borehole pumps. The unit is easily calibrated and then monitors all important pump characteristics. All parameters are saved in non-volatile memory to be available even after power loss. A re-start delay ensures the borehole replenishing before pumping starts again.

 

Features:

 

  • High resolution analogue microprocessor
  • High current sensing input (up to 15A)
  • Automatic diagnosis of pump
  • Fixed start-up delay (10 sec)
  • Front face calibration / reset button
  • Monitors over and under current
  • Three retries for over current
  • Under current ( dry running ) restart delay
  • Monitors over and under voltage
  • Security input to control pump
  • Modular 35.5mm DIN rail mountable
  • High current 16A SPST output relay
  • LED indication for faults
  • LED indication for power supply ON
