Series dc-dc converters represents broad flexible range power supplies advanced electronic systems. Features include high efficiency, high reliability, output voltage noise excellent dynamic response load/line changes. converter inputs protected against surges transients. input over- undervoltage lockout circuitry disables outputs input voltage outside specified range. Certain types include inrush current limiter preventing circuit breakers fuses from tripping switch-on. outputs open- short-circuit proof protected against overvoltages means built-in suppressor diodes. outputs inhibited logic signal applied (i). inhibit function used, must connected with enable outputs. indicators display status converter allow visual monitoring system time. Full input-to-output, input-to-case, output-to-case output-tooutput isolation provided. converters designed built according international safety standards IEC/EN 60950 have been approved safety agencies (USA Canada). case design allows operation nominal load free-air ambient temperature. forced cooling provided, ambient temperature exceed case temperature must remain below under conditions. temperature sensor generates inhibit signal which disables outputs case temperature exceeds limit. outputs automatically re-enabled when temperature drops below limit.

Parallel Series Connection Single double-output models with equal nominal output voltage connected parallel without precautions using option With option (current sharing), models share current approximately equally. Single output models and/or main second outputs doubleoutput models connected series with other (similar) output.
