For the automatic switching of capacitor banks to achieve target power factor, NHP has released the new RL8 and RG8 power factor controllers.

With an intuitive easy-to-use interface, the new series offers plug-and-play accessory modules providing flexibility to meet any application requirement with options from master-slave configurations to contactor or dynamic switching of capacitor banks.

Features provided as standard include IP65 front protection, network measurement values including harmonic measurement, step status information and defined alarms.

Communication modules are available as plug and play for RS485 or Ethernet MODBUS connectivity for both RL8 and RG8 controllers.

The features of the standard RL8 controller include:

  • Eight relay outputs expandable to 14 steps
  • Voltage and current THD up to 15th harmonic
  • Two expandable slots
  • Built-in temperature sensor

The features of the advanced RG8 controller include:

  • Eight relay outputs expandable to 16 steps
  • Voltage and current THD up to 31st harmonic
  • Eight configurable user alarms
  • Four expandable slots
  • Dynamic switching via thyristor control module (NPFCEXP1001)
  • Advanced programmable I/O functions
  • Built-in temperature sensor
  • Master/slave functionality

The RL8 controller will soon feature as a standard on PFCW, PFCE and PFCP Power Factor Correction systems.

To help achieve your power factor correction needs, NHP provides reliable devices with advanced technological features.
