Switching power supply, rated output 12W. Standby loss only 0.2 watts. Modular device for mounting on DIN-EN 60715 TH35 rail. 1 division unit = 18mm wide, 58mm deep. If the total power requirement of a series 14 bus system is higher than 8W, additional switching power supplies FSNT14-12V/12W are required. These each supply a group of actuators, which are separated with a separating bridge on the FSNT14. The scope of delivery includes 1 separating bridge TB14 1 TE, 1 jumper 1.5 TE and a spacer DS14. With a load greater than 50% of the rated output and always with switching power supplies and dimmers next to each other, 1/2 division unit ventilation distance with the DS14 spacer is required. This and a long jumper are therefore included. Input voltage 230V (-20% to +10%). Efficiency 83%. Stabilized output voltage ±1%, low residual ripple. Short-circuit proof. Overload and overtemperature protection by switching off with automatic switching on after the error has been eliminated (autorecovery function). This switching power supply can also be used to create redundancy. For this purpose, only 1 FSNT14 may be connected in parallel to the integrated power supplies in the FAM14 and FTS14KS and connected with a normal jumper. For optimal load distribution, the FSNT14 should be placed next to the last actuator in the bus if possible.
