Programmable Power Supply NGPE is suitable for use in test systems and for general laboratory applications. The relatively small output capacitance, the short setting time even for down programming (thanks to built-in current sinking) as well as the voltage and current monitoring outputs are significant benefits in system use.

Features & Benefits

  • 0 to 40 V/0 to max. 40 A
  • Primary-switched regulator with high efficiency and low heat dissipation
  • Low PARD, excellent EMC, RFI suppression grade B
  • Good regulation characteristics even with partial loading thanks to push-push converter configuration using power FETs
  • Wide AC supply regulation range: 190 to 265 V/95 to 135 V
  • Manual setting or via IEC/IEEE bus
  • Clear front-panel layout and LED display for voltage and current as well as IEC/IEEE-bus commands
  • Separate panel meters for voltage and current, each with two switch-selected ranges
  • High resolution and reproducibility due to decade setting
  • High setting speed (for up programming independent of preset current limit, for down programming due to current sinking)
  • Current monitoring output (two ranges)
  • Voltage monitoring output
  • Overvoltage protection (OVP)
  • Thermostat-controlled cooling fan
  • Remote sensing similar to NGPV
  • 19" system unit
