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 volt-
ages i.e. 12/24 VDC or 24/48 VDC battery voltages. High efficiency
allows operation up to 75C without derating. Input filtering accprding to
EN 55022-A and FCC, level A. Low output ripple minimise design-in time
and cost.
