Product Details

Four supervised input channels, two regulated outputs

The receiver accepts power from up to four independent Fault Managed Power channels across two field-terminated input ports, with two channels per port. Each channel supports up to 5 A, with a combined input-current limit of 12 A. Nominal input is 350 VDC and must be supplied by a compatible UL Recognized or Listed Clearfield FMP transmitter shelf to form the supervised Class 4 circuit. 

Two output ports provide regulated constant-voltage power at 51–57 VDC, with a nominal output of 56 VDC. Each port supports up to 45 A, subject to a combined maximum output current of 45 A. The receiver delivers up to 2,500 W at up to 95% efficiency and uses 8 AWG field wiring on the output side. 

• Output power: Up to 2,500 W 
• Output voltage: 51–57 VDC, 56 VDC nominal 
• Output current: 45 A maximum total 
• Full-load efficiency: 95% typical 
• Enclosure rating: IP66 

Built for unattended outdoor operation

The finned enclosure is rated IP66 per IEC 60529 and operates from -40 °C to 70 °C. Cold starts are limited to -20 °C, and output power is derated above 46 °C. For outdoor installations, the receiver must be mounted vertically with its connectors facing down to maintain the IP66 rating and maximize cooling. A sunshield is required when the unit is exposed to direct sunlight. 

Integrated protection includes common-mode surge protection up to 6 kV and differential-mode surge protection up to 1 kV, with support for up to five surges at each rating. The receiver also protects against short circuits, overload, over-voltage, and over-temperature conditions. It automatically recovers after overload or over-temperature conditions clear, while an over-voltage shutdown requires the unit to be re-powered.

Important: the output circuit between the receiver and the load is not a protected FMP / Class 4 circuit. The unit must be de-energized before contacting any exposed output conductors, and the receiver is intended for installation in a Restricted Access Area accessible only to skilled or properly instructed persons, per IEC 62368-1.

Features & Benefits

Safety by design

• Paired with a compatible Clearfield FMP transmitter, the receiver completes a supervised Fault Managed Power circuit installed as a Class 4 circuit in accordance with NFPA 70 Article 726. 
• The receiver must be used with a compatible FMP transmitter for Class 4 compliance. Any UL 1400-2 listed Class 4 cable may be used between the transmitter and receiver. 
• Over-voltage protection shuts down the output at 60–67 VDC and requires the receiver to be re-powered before operation resumes. 
• Designed for installation in a Restricted Access Area in accordance with IEC 62368-1. 
• The output circuit between the receiver and connected equipment is not a protected FMP or Class 4 circuit. The receiver must be de-energized before contacting exposed conductors or connecting or disconnecting a load. 

Outdoor-ready construction

• IP66-rated enclosure for outdoor operation from -40 °C to 70 °C, with cold starts limited to -20 °C and output derating above 46 °C. 
• Vertical outdoor mounting with the connectors facing down maintains the IP66 rating and supports proper cooling. 
• Sunshield is required when the receiver is exposed to direct sunlight and is available separately. 
• Supports wall or pole mounting, with an optional pole-mount kit available for field installation. 
• Weighs 24 lb without the sunshield and 30 lb with the sunshield. 
• Backed by a three-year warranty. 

Regulated, high-power DC output

• Delivers up to 2,500 W of constant-voltage power at 51–57 VDC, with a nominal output of 56 VDC. 
• Supports up to 45 A per output port, subject to a combined maximum output current of 45 A. 
• Provides up to 95% efficiency, with 95% typical efficiency at full load. 
• Integrated protection addresses output surge, short-circuit, overload, over-voltage, and over-temperature conditions. 
• Automatically recovers after overload and over-temperature conditions clear. Over-voltage shutdown requires the receiver to be re-powered. 
• Uses 8 AWG output wiring with field-wireable, screw-terminated connectors. 

Fast field diagnostics

• Front-panel LEDs provide status for each of the four input channels, communications, output power, and four fault categories. 
• Dedicated fault indicators identify load, environmental, internal, and input or system conditions without requiring a laptop. 
• Each fault category corresponds to a documented troubleshooting path, including checking wiring, reducing the load, adding transmitter pairs, or contacting support. 
• In-line communications between the FMP transmitter and receiver support end-to-end system operation and monitoring. 
• Clearly identified input, output, and protective-earth connections support accurate field termination.
