By supplying 57V DC (within the 802.3af\/at PoE envelope), the MT48-570080-11DG keeps voltage well within the operating range of compatible MikroTik devices even over 100m+ runs.\u003c\/p\u003e\n\u003cp\u003eGPEN Concept\u003cbr\u003e\nThis PSU is the recommended power source for MikroTik’s GPEN ecosystem – GPER series units and similar products – which use inexpensive Ethernet cabling in place of single-mode fibre for point-to-multipoint subscriber deployments.\u003c\/p\u003e\n\u003cp\u003eSpecifications\u003cbr\u003e\n– Input: 100-240V AC, 50\/60Hz (universal)\u003cbr\u003e\n– Output: 57V DC, 0.8A (45.6W)\u003cbr\u003e\n– Connector: Standard DC barrel jack\u003cbr\u003e\n– Power efficiency: Level VI (ErP compliant)\u003cbr\u003e\n– Cooling: Fanless, convection cooled\u003c\/p\u003e","brand":"MikroTik","offers":[{"title":"Default Title","offer_id":67626089480421,"sku":"RB57POW","price":490.0,"currency_code":"ZAR","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0736\/0010\/6725\/files\/RB57POW_1.webp?v=1791396674","url":"https:\/\/guardsondutyshop.co.za\/products\/mikrotik-mt48-570080-11dg-57v-0-8a-power-supply-for-long-ethernet-runs","provider":"Guards On Duty Shop \u0026 Security Guards ","version":"1.0","type":"link"}
