Current limiter module WÖHRLE POWER-TEC 10.4

POWER-TEC 10.4 is a 4-channel electronic fuse (e-Fuse) load switch with independent overcurrent limit control and real-time output current indication. Each channel is separately protected so that overload or fault conditions on an individual load do not affect overall system reliability or function. 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 volt-free DC-OK output can be used to monitor system function. Each channel can also be switched ON or OFF to ease fault diagnostics or for maintenance. POWER-TEC 10.4 is available with 10 A maximum channel current and 150 % power boost for 5 s but can handle 150 % overload for up to 120 ms to avoid nuisance tripping. The channels power up in sequence to reduce the input inrush current with a pre-settable delay time. Under system overload conditions, the channels will disconnect the loads in reverse sequence, keeping essential functions running to the last. Output overload hiccup or tripping mode is adjustable by a switch. The e-Fuse has a high lifetime expectancy of >80.000 h / 40 °C and easy wiring with tool-less push-in and lever-release terminals. The input and output terminals are also paired to allow easy daisy chaining.
