NOTSTROMVERSORGUNG REG-KNX

REG emergency power supply. To buffer the bus voltage. If a complete mains failure occurs, an external lead gel battery with a voltage of DC 12 V (SELV) can be connected to the REG power supply for buffering. The lead gel battery is recharged or maintained in its charged state by integrated charging electronics. A binary input can be connected in order to register the operational statuses (mains voltage, error warning, battery operation). For installation on DIN rails TH35 according to EN 60715. A data rail is not necessary. Nominal voltage: AC 110-230 V ±10%. Operating voltage: min. AC 92 V - max. AC 253 V. Mains frequency: 50-60 Hz ±10%. Output to power supply: Output voltage: DC 30 V ±2 V. Output current: without battery with mains supply max. 300 mA, with battery without mains supply max. 640 mA. Buffer time with lead gel battery 7,2 Ah: MTN683890: approx. 0.5 h. MTN683832: approx. 1 h. Buffer time with lead gel battery 18 Ah: MTN683890: approx. 1.25 h. MTN683832: approx. 2.5 h. Short-circuit current: 1.5 A. Charging current: max. 1 A. Connections: plug-in screw terminal for main connector, operating state (4-pin, 3 floating contacts) and emergency power supply. Plug-in terminal for battery connection (two 1 mm pins). Device width: 4 modules, approx. 72 mm. Contents: With connecting terminal and cable cover. Colour: light grey.
