Calex Mfg. Co. Inc. announces the availability of the Calex 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 2.5 to 15V and dual output voltages available are +/-5, +/-12 and +/-15 Volts. All models are isolated input to output. The switching frequency of the EW Series is 400 kHz. Efficiencies run as high as 87% typical. The input to output isolation voltage is 1500 Volts DC. Output noise is only 50 mV 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 backed by Calex’s five year warranty. The operating case temperature range of the EW series is -40 to +90C. MTBF is calculated per MIL-HDBK-217F at 1M hours.
