Calex Electronics Limited announces the 10 Watt EW Series. The 10 watt DC/DC converters are housed in a 1.25” x 0.8” x 0.4” five sided shielded case. The EW series offers both single and dual output models. The input voltage ranges available are 9 to 18V, 18 to 36V and 36 to 75V. Single output voltages range from 2.5V to 15V and dual output voltages available are +/-5V, +/-12V and +/-15V. All models have isolated outputs.

The switching frequency of the EW series is 400khz and efficiencies run as high as 87% typical. The input to output isolation voltage is 1500V DC, output noise is only 50mV peak to peak. Line and load regulation is 0.3% and 0.5% respectively, output voltage accuracy is 0.6%. All EW models are protected by continuous short circuit protection and have a five year warranty.

The operating case temperature range of the EW series is -40 to 90ºC and the MTBF is calculated per MIL-HDBK-217F at 1M hours.
