Description:Product Name: Universal Switching Power SupplyPlace of Origin: ChinaThe universal switch power supply adopts power semiconductor as the switching element. The output voltage is adjusted by making and breaking the switch periodically and control the time ratio of off to on of the switch elements. Meanwhile, it has over-current and over-voltage protection. It has the advantages of small output wave, high efficiency, small volume, light weight, and elegant appearance. Main technical parameters: 1) Output power: 15W, 25W, 30W, 35W, 40W, 50W, 60W, 100W, 120W, 150W, 180W, 200W, 240W, 280W, 320W, 350W 2) AC input voltage: 176 - 264V, 85 - 162V (switch selection) 3) AC input frequency: 47 - 63Hz 4) Electric network adjusting rate: ≤±1% 5) Load adjusting rate: ≤±8% 6) Output stability: ≤ ±8% 7) Frequency (full load): ≥78% 8) Readjustment range of output voltage: ±10% (main circuit) 9) Output wave (resistive load) peak: ≤120mV 10) Output over-voltage protection: 115 - 135% 11) Output over-current protection: 110 - 150% 12) Insulation resistance: 50MΩ 13) Remark: special specifications can be made to order
