RECOM Power RACPRO1-4SP DIN-Rail e-Fuses
RECOM Power RACPRO1-4SP DIN-Rail e-Fuses are four-channel electronic fuse (e-Fuse) load switches featuring independent overcurrent limit control and real-time output current indication. Each channel is protected separately so that faults or overloads on an individual load do not affect the overall system's function or reliability. The devices include LED indicators that show output current, changing from green to yellow (current within limit) to orange (current at limit) to red (overcurrent or short-circuit). A volt-free DC-OK output can be used to monitor system function. Each channel can be switched ON or OFF for maintenance or to ease fault diagnostics.
The RACPRO1-4SP series offers 5A and 10A maximum channel current and 150% power boost for 5s and handles >150% overload for up to 100ms to avoid nuisance tripping. The channels power up in sequence to lower the input inrush current with a pre-settable delay time. Under system overload conditions, the channels disconnect the loads in reverse sequence. The output overload hiccup or tripping mode is adjustable by a switch, and the 5A variant can also be set to limit the available power to below 100W for LPS installations (NEC Class 2).
RECOM Power RACPRO1-4SP DIN-Rail e-Fuses offer a high lifetime expectancy of >80,000h/+40°C and easy wiring with tool-less push-in and lever-release terminals. The input and output terminals are paired for easy daisy chaining, and the devices can be used with any 24V DC power supply.
