Custom designed Power Distribution Units for your specific application

Power Distribution Units (PDUs), also sometimes referred to as Power Vaults or Power Distribution Assemblies, are transformers housed in NEMA rated enclosures that are used as main AC power for system power distribution. These units often include primary and secondary circuit protection as well as other electronic features. They can be stand-alone products located away from the customer’s product or can be incorporated in an existing product housing in rackmount or custom sized enclosures. Features of PDUs designed by QTE include:

  • Custom number of inputs/outputs
  • Custom input/output voltages
  • Power monitoring
  • Optional over current protection
  • NRTL to UL certifications and CE Mark

Specifying Power Distribution Units

Below are somethings that will be needed in order to properly specify your next PDU:

Power Rating Up to 1.5MVA
Frequency 50Hz
60Hz
400Hz
up to 20kHz
Primary Voltage Required voltages below 600V
Secondary Voltage and Current
  • What secondary voltage and current will you need (multiplied together, these give you VA or kVA)
  • How many secondaries will you need?
  • If you have multiple secondaries, will you be using them at the same time?
Other Options What other value-added options do you need? We offer the following and more:
  • Enclosures
  • Casters
  • Circuit breakers
  • EMO switches
  • Input connections
  • Output connections
  • Need for design to accommodate low inrush, low impedance, K-Factor rating, current limiting, etc.

If for any reason you are having trouble figuring out the above mentioned aspects of your next PDU, still feel free to give us a call. Our sales representatives are technical staff that can help you find the needed information.
