Бутони KNX 4GANG с IR приемник SYSM

KNX emergency power supply is specifically designed to buffer the KNX bus voltage during a mains power failure. If a complete mains failure occurs, an external lead gel battery with a voltage of DC 12V 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 status (mains voltage, error warning, battery operation). It does not require a data rail for installation on DIN rails TH35 according to EN 60715, which simplifies installation. Its Ue rated operational voltage is 230VAC at 50/60Hz. Its output voltage is 30V±2V DC, output current without battery with mains supply is max. 300mA, and output current with battery without mains supply is max. 640mA. Buffer time with lead gel battery 7.2Ah: MTN683890 is approx. 0.5h and for MTN683832 is approx. 1h. Buffer time with lead gel battery 18Ah: MTN683890 is approx. 1.25h and for MTN683832 is approx. 2.5h. The short-circuit current is < 1.5A and the charging current is max. 1A. It has plug-in screw terminal for main connector, operating state (4-pin, 3 floating contacts), emergency power supply and has a plug-in terminal for battery connection. The device width is approx. 72mm and has 4 modules. The color of the product is light grey.
