Feature: Power
With active current limitation, all other outputs continue to be supplied with the proper voltage, particularly important in the case of sensitive and safety-critical loads
Te FIEPOS product family (Figure 2) has two versions:
Te Basic series with one DC output with an optional integrated decoupling MOSFET for developing redundant power supply systems; and the eFused series with up to four current-limited DC outputs. FEIPOS simplifes the delivery of selective current distribution, protection and monitoring directly in the field, with no need for further accessories or costly, bulky enclosures. FIEPOS
supplies are manufactured using a combination of modular boards, futureproofing them by allowing new functions to be added by simply integrating alternative boards as required.
Selective current distribution and protection Te eFused range of FIEPOS power supplies offers an alternative to power sources that are protected by means of an external electronic four-channel protection module, four external fuses or circuit breakers. To deliver selective current distribution, the eFused versions can integrate up to four electronic fuses, allowing them to simultaneously supply electromechanical loads such as motors, and sensitive loads such as controls or sensors, from a single decentralised and fused power supply. If there’s a short-circuit, the power supply selectively shuts
down only the faulty output and reports this via the IO-Link or Output-OK signal and the LED interface on the front of the device. Due to active current limitation, all other outputs continue to operate normally. Tis is particularly important in the case of sensitive and safety-critical loads such as PLCs or sensors.
