AC Power Supply Module Type 1 with Power Access (ACP-1PA)

Features and Benefits

  • 110VAC Input / 25.5VDC 25W Output Power Supply
  • Fully Sealed Enclosure (NEMA 4X, 6, 13 Protection)
  • -40°C to +65°C (-40°F to +149°F) Operating Range
  • MIL-S-901D Grade A for High Impact Shock
  • MIL-STD-167B for Vibration
  • MIL-STD-461E for Electro-Magnetic Interference (Pending)
  • Compatible with MIL-STD-1399 Section 300 Voltage Spike
  • Supports Hot Swapping
  • Multiple Modules Can be Paralleled to Provide Load Sharing, Uninterrupted Power During Hot Swap, and/or Redundant Power Sources
  • Modules will function with both Chameleon and Chameleon+ products

The Chameleon 25W AC Power Module with Power Access (ACP-1PA) isolates, filters, and converts an AC input source into a regulated DC output to power external devices.  The ACP-1PA is derived from the standard ACP-1 module.  The ACP-1PA is intended to serve as a power supply for external devices only.  The standard ACP-1 version is intended to serve as a power supply for other modules in a Chameleon node (these other modules may in turn feed external devices thru a lower power secondary regulated output).

Multiple power modules attached to each other and fed from different power sources 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.

ACP-1PA units are hot-swappable: should the need arise 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 and automatic output over-current shutdown.

When all these features are combined, the ACP-1PA has the functionality to create a redundant expandable stand-alone DC power supply.  Simply add-on power modules to increase power output and/or redundant connections.

As with all Chameleon modules, the ACP-1PA 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.
