It’s factory-set to 12VDC but can be switched to 6VDC or 24VDC to match a range of devices. The unit accepts common low-voltage transformer inputs and includes protections and monitoring features that simplify installation and operation.\u003c\/p\u003e\n\n\u003ch3\u003eHow does the SMP3 keep critical devices running during power loss?\u003c\/h3\u003e\n\u003cp\u003eThe SMP3 charges a sealed lead-acid or gel cell and automatically transfers to battery output if AC power fails, keeping connected devices powered without manual intervention. The charger supplies a gentle, regulated charge to preserve battery life and prevents overcharge.\u003c\/p\u003e\n\u003cul\u003e\n  \u003cli\u003eAuto-transfer to battery on AC fail for uninterrupted operation.\u003c\/li\u003e\n  \u003cli\u003eSealed lead-acid\/gel compatible charging with max ~350–550mA charge current depending on configuration.\u003c\/li\u003e\n  \u003cli\u003eOvercharge protection and regulation to extend battery lifetime.\u003c\/li\u003e\n  \u003cli\u003eLED status shows AC present or battery-mode for quick diagnostics.\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003eWhat input and output options does it support?\u003c\/h3\u003e\n\u003cp\u003eThe module accepts low-voltage AC from 16VAC up to 28VAC and provides switch-selectable DC output of 6V, 12V or 24V at up to 2.5A continuous.

Built-in diagnostic logic can also indicate overloads, short circuits and battery undervoltage states so you can respond quickly.\u003c\/p\u003e\n\u003cul\u003e\n  \u003cli\u003eGreen LED = AC present and normal operation.\u003c\/li\u003e\n  \u003cli\u003eRed LED = DC\/battery backup mode active.\u003c\/li\u003e\n  \u003cli\u003eCombined LED states convey short circuit, overload, or battery issues.\u003c\/li\u003e\n  \u003cli\u003eClear terminal labels simplify identifying AC, DC and battery connections.\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003cp\u003eWho is this for? Installers and technicians specifying compact power solutions for small security panels, CO\/smoke detectors, access controls, and other low-voltage devices will value the SMP3 for its flexible outputs, built-in battery charger and small footprint. It’s a practical choice when space is limited but reliable regulated DC and battery redundancy are required. Professional installation is recommended to meet local electrical codes and ensure correct transformer sizing and wiring. YABUYALI provides pre-tested units and support materials to help with integration into existing systems.\u003c\/p\u003e\n\u003csection class=\"product-faq-snippet\"\u003e\u003ch3\u003eFAQ\u003c\/h3\u003e\n\u003cdiv class=\"faq-item\"\u003e\n\u003cp class=\"faq-q\"\u003eQ: Which voltages can the SMP3 supply?\u003c\/p\u003e\n\u003cp class=\"faq-a\"\u003eA: The SMP3 is switch-selectable for 6V, 12V (factory) or 24V DC output at up to 2.5A continuous.\u003c\/p\u003e\n\u003c\/div\u003e\n\u003cdiv class=\"faq-item\"\u003e\n\u003cp class=\"faq-q\"\u003eQ: What battery types does it support and does it auto-switch?\u003c\/p\u003e\n\u003cp class=\"faq-a\"\u003eA: It supports sealed lead-acid and gel batteries, charges automatically, and switches to battery power on AC loss.\u003c\/p\u003e\n\u003c\/div\u003e\u003c\/section\u003e","brand":"YABUYALI","offers":[{"title":"Default Title","offer_id":48413591699613,"sku":"B0G11BTLQ3","price":50.93,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0766\/9596\/1757\/files\/yabuyali-smp3-front-panel.jpg?v=1781273027","url":"https:\/\/nexoltic.com\/products\/yabuyali-smp3-power-supply-charger-6-12-24v-2-5a","provider":"Nexoltic","version":"1.0","type":"link"}
