DC Power Supply Module Type 1 (DCP-1)

Features and Benefits

  • 25W 10 to 60 VDC Power Supply
  • Fully Sealed Enclosure (NEMA 4X, 6, 13 Protection)
  • -40°C to +65°C (-40°F to +149°F) Operating Range
  • MIL-STD-901D Grade A for High Impact Shock
  • MIL-STD-167B for Vibration
  • MIL-STD-461E for Electro-Magnetic Interference (EMI)
  • Supports Hot Swapping
  • Multiple Modules Can be Paralleled to Provide Load Sharing, Uninterrupted Power During Hot Swap, and/or Redundant Power Sources

The Chameleon 25W DC Power Module (DCP-1) filters, pre-regulates, and distributes electrical power to other Chameleon modules connected to it.  Multiple power modules attached to each other and fed from different power sources (AC and/or DC) can provide seamless redundancy, reducing susceptibility to power outages, or provide load sharing to increase the available power.  Power modules on the same node are always online—if one should lose input power, another will instantaneously compensate and deliver uninterrupted power to all loads.

DCP-1 units are hot-swappable: to replace one, simply swap the front panel (with attached power board) and the unit is back online—there is no need to shut off the power. When the module is swapped out, all storage capacitors are automatically discharged to prevent shocking hazard. The module also features input circuit fusing, automatic output over-current shutdown, and reverse input voltage protection.

As with all Chameleon modules, the DCP-1 offers unequaled ruggedness.  It is specifically designed for sustained operation in severe environments, including those characterized by extreme shock, vibration, electro-magnetic interference, temperature, and/or humidity.  Its fully-sealed enclosure (sealing end-caps not pictured) ensures long-lasting operation in the grimiest settings.  In fact, Chameleon modules can operate fully submerged.
