The TEN 4 series DC/DC converter is designed for applications requiring very wide operating voltage range. Typical applications are tele-and data communication systems, mobile battery powered equipments and industrial process control systems with operation from different input voltages i.e. 12/24 VDC or 24/48 VDC battery voltages. High efficiency allows operation up to +75°C at full load. Input filtering according to EN 55022-A and FCC, level A. Low output ripple minisme design-in time and cost.
