SYNERGY21 PoE+ constante stroom driver 350mA 12-24V DC 8,4W (S21-3701)

Delivers a constant 350 mA output from any IEEE 802.3at PoE+ network, with an adjustable 12–24 V DC output for LED lighting and smart home devices.

Overview

The SYNERGY21 S21-3701 is a PoE+ constant current driver that converts 48–57 V DC from Power over Ethernet into a regulated 350 mA current. It supports output voltages from 12 V to 24 V DC, providing up to 8.4 W for connected loads. The unit features an RJ45 input for PoE and screw terminals for the output, housed in a plastic enclosure.
