Calex Intros 10W DC/DC Converters
Shielded DC/DC converters.
Concord, CA — Calex Mfg. Co., Inc. has introduced its 10 Watt EW Series of DC/DC converters which are available in both single and dual output models. 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 ±15V. All models are isolated input-to-output.
The switching frequency of the EW Series is 400kHz, and efficiencies run as high as 87 percent typical. The input to output isolation voltage is 1500VDC. Output noise is only 50mV peak-to-peak. Line and load regulation are stated at 0.3 percent and 0.5 percent respectively. Output voltage accuracy is 0.6 percent.
All EW models are protected by continuous short circuit protection. They are housed in a 1.25 x 0.8 x 0.4-in. case, shielded on five sides. Operating case temperature range is -40 to +90°C. MTBF is calculated per MIL-HDBK-2217F at 1M hours.
