Calex Mfg announces the availability of the 75 Watt Triple Output HE Series DC/DC converters. The HE Series offers a variety of models in an industry standard half brick package which provide three regulated DC outputs. All models are fully isolated input to output with output voltages of 3.3 VDC and 5 VDC on the primary and +/-12, +/-15 and +/- 17 VDC on the secondary outputs. The HE Series is available in RoHS and non-RoHS and backed by Calex's Five Year Warranty.

The operating temperature range of the HE Triple is -40 to +100 C. The switching frequency is fixed at 325 kHz. Efficiencies are as high as 89%. All models are protected by pulse-by-pulse current limiting, over-temperature protection and over-voltage protection. ON/OFF is available for energy saving operation. The OFF idle current of the HE is 2 mA. Trim is also available with a +/-10% trim range. Two input ranges are available with the HE Triple output converters, 18 to 36 VDC and 36 to 75 VDC.
