DDCC//DDCC SSWWIITTCCHHIINNGG PPOOWWEERR SSUUPPPPLLYY DC INPUT 12-24, 24-48 DC INPUT 12-24, 24-48 SINGLE OUTPUT SINGLE OUTPUT 10 WATTS 10 WATTS OHSxSCx SERIES Application Telecommunication, office equipment, industrial machines and electronics, automation, robotics, household equipment. General Description In response to market demands fordistributed power ETA have developed a new DC/DC converter, suitable for PCB mounting. The open board design of this series resulted to a lighter weigh, lower cost and smaller size. This is an industries pin configuration. Wide input voltage range covers 8VDC to 32VDC and 18VDC to 72 VDC. Dimension: 25.4Wx50.8Lx11H mm Features 1Wx2Lx0.44H Inch 1.PCB Mountable 2. Small , Light Weight 3. Isolation Voltage: 500 Vmin 4. Ultra wide input-range(4-72Vdc) 5. Wide operating temp. Range(-20C~+71 C) 6. Small input current at no load 7. Fixed switching frequency 170kHz 8. Over current protection 9.
