MPOD Low Voltage Module

Multichannel Low Voltage Modules

WIENER presents with Mpod a new, universal multi-channel low voltage (LV) and high voltage (HV) computer controlled power supply system. Offering highest channel density the MPOD mainframe can house up to 10 plug-in modules which can be mixed in type and parameters. Up to 80 individually controlled low voltage channels are available in one mainframe

All Mpod low voltage modules have either 8 or 4 channels with a maximum of power 50W or 100W per channel in different voltage ranges. All channels are individually controlled and monitored and have floating, sensed outputs. A control input for each channel can be used for Interlock / Inhibit or external hardware ON/OFF. The new High Precision MPV series allows up to 21 bit resolution for voltage and current measurement


  • Low Voltage floating modules with 8 or 4 channels of 50W or 100W max. with 0-8V, 0-16V, 0-30V, 0-60V and 0-120V ranges
  • 6U height, 220mm deep fully shielded mechanics
  • All  DC outputs with individual  return lines,  individually sensed,  floating channel  to channel and channel to chassis ground (125V, 500V optional)
  • Extremely low noise and ripple: <3mVpp (0-20MHz)
  • Voltage and current settings / monitoring for each channel, 15 bit resolution, accuracy +/-0.1% of full scale value (Standard Series) and 21 bit resolution for High Precision Series
  • Current monitoring and limiting for each channel, 15 bit resolution (Standard Series) and 21 bit resolution for High Precision Series
  • high stability, 0.2%/10k
  • Programmable channel parameters:
    • Terminal and load voltage, under voltage / over voltage trip points
    • current limit (current or voltage controlled mode)
    • power, regulation type, internal / external sense
    • ramping speed up and down (1V/s … 500V/s)
    • group features / error handling
  • programming and monitoring via Mpod controller Ethernet (TCP/IP) and USB ports
  • Output Connectors: 2 x 37 pin sub-D for DC and sense  (4 or 2 channels each)
  • Front panel multi-color Status LED for each channel
  • Dimensions: 6U x 40.64mm x 220mm
  • Weight: ca. 2 kg
