It gives a steady DC 29 V output at 640 mA. This is enough to run a standard bus line with up to 64 devices.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003e\u003cspan style=\"color: #09427b;\"\u003eTechnical Specs\u003c\/span\u003e\u003c\/strong\u003e\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003eChoked Output: The primary bus connection features an integrated choke. The choke decouples the DC power from the line, preventing the high-frequency data telegrams on the network from short-circuiting\u003c\/li\u003e\n\u003cli\u003eAdditional Unchoked Output: This secondary output provides standard DC 29 V without a choke. It is widely used to power auxiliary components or to supply a separate, second KNX bus line via an external choke\u003c\/li\u003e\n\u003cli\u003eBuffer Interval: Bridges short mains power disruptions of up to 200ms at rated current to preserve network communication.\u003c\/li\u003e\n\u003cli\u003eIntegrated Reset Button: Built-in slide\/reset switch. Holding it down for more than 20 seconds completely disconnects the bus voltage to return connected bus devices to their initial state for troubleshooting or testing.\u003c\/li\u003e\n\u003cli\u003eDiagnostic LEDs: Clear visual indicators on the front panel display standard operating status, overloading, or voltage interruptions\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"Bemco KNX","offers":[{"title":"Default Title","offer_id":57524404453758,"sku":"N 125\/22","price":323.0,"currency_code":"GBP","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0910\/9753\/0750\/files\/SiemensN12522KNXPowerSupplyUnit.png?v=1782287335","url":"https:\/\/bemco-knx.co.uk\/products\/siemens-n125-22-knx-power-supply-unit-dc-29v-640-ma-with-additional-unchoked-output","provider":"Bemco KNX","version":"1.0","type":"link"}
