NHP RG8 and RL8 power factor controllers

For the automatic switching of capacitor banks to achieve target power factor, NHP has released the RL8 and RG8 power factor controllers. With an intuitive, easy-to-use interface, the 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 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.

RL8 controller features include: eight relay outputs expandable to 14 steps; voltage and current THD up to 15th harmonic; two expandable slots; and a built-in temperature sensor. The controller will soon feature on PFCW, PFCE and PFCP power factor correction systems.

RG8 controller features 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); programmable I/O functions; a built-in temperature sensor; and master/slave functionality.
