ES51 High Voltage power supply

Product Overview

The ES51 high voltage power supplies are power supply units for the series R5X AC discharge bars.

The discharge bars and the ES51 power supply are used mainly in cases where disruptive static charges on fast-moving material webs impair production processes and need to be eliminated.

The ES51 power supply features the following characteristics:

  • 5 plug-type high voltage outputs
  • stable 5 kV AC output voltage
  • small dimensions
  • easy installation
  • protection class IP 54 design
  • function and pollution monitoring of the bars with floating signal contacts (optional)
