Eltako FSNT14-12V/12W Switching power supply 12V/12W

Switching power supply with a rated power of 12 W. Standby loss is only 0.2 watts. It is a modular device for mounting on a DIN rail according to EN 60715 TH35. One module is 18 mm wide and 58 mm deep. If the total power requirement of a series 14 bus system exceeds 8 W, additional FSNT14-12V/12W power supplies are required. Each of these supplies a group of actuators that are separated by a terminal bridge on the FSNT14. Included in the delivery are a terminal bridge TB14 1 TE, a jumper 1.5 TE, and a spacer DS14. When loading more than 50% of the rated power, and always with adjacent power supplies and dimmers, a ventilation gap of 1/2 module is required using the spacer DS14. Therefore, this and a long jumper are included in the delivery. The input voltage is 230 V (-20% to +10%). The efficiency is 83%. The stabilized output voltage has a tolerance of ±1% and low residual ripple. The switching power supply is short-circuit proof and features overload and over-temperature protection by switching off with automatic reconnection after the fault is cleared (auto-recovery function). This switching power supply can also be used to create redundancy. For this purpose, only one FSNT14 may be connected in parallel to the integrated power supplies in the FAM14 and FTS14KS and connected with a normal jumper. The FSNT14 should be placed as close as possible to the last actuator in the bus for optimal load distribution.
