Switch mode buffer power supply units PWB are intended for continuous power supply to devices that require stabilised voltage of 52 V (e.g. PoE power systems, PoE switches). Built-in DC/DC converter allows to reduce costsof installation by reducing number of required batteries. Additional advantage is output voltage stabilisation regardless of battery charge status. Power supply: ~200 - 240 V. Power supply output: 1.15A/52VDC. Efficiency: 83%. Dimensions: 200 x 120 x 48 [+/-2 mm]. Protections: SCP, OLP, OVP, UVP.
