The Honeywell FC-PSU-UNI4825U power supply is a UL-approved switched-mode DC power supply with high efficiency (>87% at 230 Vac). It accepts a wide range of input voltages to provide 48 Vdc and 25 A output.

Main Features

• Dual built-in over-voltage protection to comply with DIN V 19250 and VDE V 0801 standards.
• ON/OFF switch on the power supply allows for online replacement in a live system.
• Current limit feature to cap the maximum output power at 1200 W.
• 100 ms holdup time.
• Under-voltage alarm.
• Output diode for parallel operation.
• Optimum protection against continuous overload and short-circuiting.

Hardware Control Features

• Power switch: Green LED indicates PSU operation; red LED indicates failure or standby mode.
• Alarm contact for system monitoring.
