4 channel E-Fuse, 5A, 24Vdc

The RACPRO1-4SP series are 4-channel load switches with electronic fuse (e-Fuse) that feature independent overcurrent limit control and real-time output current indication. Each channel is separately protected so that overload or fault conditions on a single load will not affect the reliability or function of the entire system. The useful LED indicators show the output current and change from green to yellow (current within limit) to orange (current at limit) to red (overcurrent or short circuit). A voltage-free DC-OK output can be used to monitor the system function. Each channel can also be switched on or off to facilitate fault diagnosis or for maintenance purposes.

The RECOM e-Fuses are available with 5A and 10A maximum channel current and 150% power amplification for 5s, but can also be >150% overload for up to 100ms to avoid unwanted tripping. The channels switch on in sequence to reduce the input inrush current with a pre-settable delay time. If the system is overloaded, the channels switch off the loads in reverse order so that the most important functions continue to run until the end.

The output overload or trip mode is adjustable via a switch and the 5A modules can also be set to limit the available power to below 100W for LPS installations (NEC Class 2).

The e-fuses have a long life expectancy (>80,000h/40°C) and simple wiring with tool-free push-in and lever terminals. The input and output terminals are also arranged in pairs to enable simple networking.
