12 Watt Single Series DC/DC Converters Features Description ! UL Recognized ! Low Noise Output ! LC Type Input Filter These 12 Watt Single Output DC/DC converters are designed for telecommunications, industrial controls, medical equipment and instrumentation systems. The converters feature very wide input voltage ranges. ! Six-Sided Shielded Steel Case ! Very Wide Input Voltage Ranges The converter consists of a hi-speed chopper circuit using state-of-the-art MOSFET technology, isolation transformer, and high regulation linear post regulator. These provide very low noise and ultra stable output voltages. (9-36, and 24-72) ! High Efficiency Operation !

Refer to the CALEX Application Notes for the definition of terms, measurement circuits and other information. (2) Determine the correct fuse size by calculating the maximum DC current drain at low line input, maximum load then adding 20 to 25 percent. Slow blow type recommended. (3) No minimum load required. (4) Short term stability is specified after a 30 minute warm-up at full load. (5) Transient response is defined as the time for the output to settle from 100% step load change to a 1% error band (rise time of step =2 µSec). (6) Dynamic response is defined as the peak overshoot during a transient as defined in note 5 above. (7) The input ripple rejection is specified for DC to 120Hz ripple with a modulation amplitude of 1% of Vin. (8) For module protection only, with use of external fuse on input circuit, see note 2. (9) A The functional temperature range is intended to give an additional data point for use in evaluating this power supply. At the low functional temperature the power supply will function with no side effects, however sustained operation at the high functional temperature will reduce expected operational life. The data sheet specifications are not guaranteed over the functional temperature range. (10) The case thermal impedance is specified as the case temperature rise over ambient per package watt dissipated.
