POWER SUPPLY FSNT14-12V/12W

Power supply with 12W nominal power. Standby consumption only 0.2 watt. If the power requirement of the RS485 bus in the 14-series exceeds 8W, this power supply FSNT14-12V/12W is required. Each of these supplies its own group of actuators, isolated by the disconnect link TB14 supplied with the FSNT14. It can also be used as a power supply for the wireless transmitter unit FSM14-UC (28 143 02). Modular unit designed for DIN-rail mounting according to standard DIN-EN 60715 TH35. 1 module = width 18mm, depth 58mm. Delivery includes 1 disconnect link TB14, 1-module wide, 1 jumper 1.5-module wide, and spacer DS14. If the load exceeds 50% of the rated capacity and always when adjacent power supply units and dimmers are installed, a 1/2-module ventilation gap must be left between devices using spacer DS14. For this reason, wireless dimmers are always supplied with a long jumper connector. Input voltage 230V (-20% - +10%). Efficiency 83%. Stabilized output voltage ±1%, low residual ripple. Short-circuit protected. Overload protection and overtemperature shutdown, meaning current is automatically cut off and reconnected after fault removal (autorecovery). This switching power supply unit can also be used to create redundancy. Therefore, only one FSNT14 should be connected in parallel with integrated power supplies FAM14 and FTS14KS, using the standard jumper. To ensure optimal load distribution, the FSNT14 should be placed as close as possible to the last bus actuator.
