EFP-RD-UPS 24VDC Uninterruptible Power Supply (DC-UPS) / Battery Backup


Rugged Backup Supply for 4-20 mA Loops

The new panel-mount EFP-RD-UPS is a rugged 24 VDC Uninterruptible Power Supply (DC-UPS) / Battery Backup device designed to support 4-20 mA loops or other low-power DC loads for extended periods of time following loss of normal AC or DC power.



EFP-RD-UPS Key Features

  • Precision 24 VDC UPS for extended battery backup
  • Powers typical 4-20 mA loops for at least 12 days
  • Redundant battery packs and charging circuits for added reliability
  • Seismic category 1 qualification (14 g RRS)
  • Weatherproof, robust environmental qualifications
  • Ideal for use with mission-critical applications
  • Supports Spent Fuel Pool Instrumentation (SFPI)


Reliable Power for 4-20 mA Loops

The EFP-RD-UPS provides reliable power for 4-20 mA loops or other low-power DC loads for far longer and more reliably than traditional UPS or battery backup devices. This allows 4-20 mA instrumentation for process control or other mission-critical applications to continue operating during power outages or following natural disasters.



Flexible Power for a Variety of Low-Power DC Loads

The EFP-RD-UPS can also support a variety of low-power external DC loads up to 8W, including alarms, relays, displays, controllers, and sensors. High-efficiency power regulation ensures optimum battery life that tracks essentially linearly with load, up to 12 days or more.



Rugged Performance for Any Environment

Wall-mount stainless-steel NEMA 4X enclosures are designed to survive almost any environmental conditions. Tested to meet stringent NRC seismic, shock, vibration, temperature, humidity, and EMC requirements for surviving beyond-design-basis (BDB) nuclear plant events.



Simple Setup and Operation

  • Plug-and-play operation
  • Automated intelligent charging
  • Bumpless/seamless transition to backup power
  • Daisy-chain supplies for additional capacity


Multiple Configuration Options

  • Universal 85-264 VAC (47-63 Hz) power input
  • Secondary 9-36 VDC power input
  • Optional external alarm relays
  • Optional RS-232 serial interface
