The HE Series 75-W triple output dc/dc converters offer a primary output of either 3.3 Vdc or 5Vdc and auxiliary outputs of either ±12 Vdc or ±15 Vdc. The 5-V output is rated at up to 15 A, and the 3.3-V output is rated at up to 20 A. The auxiliary outputs are rated at ±2 A. The converter is housed in an industry-standard half-brick case.
The dc/dc converters are encapsulated for use in harsh industrial and military COTS applications. The operating temperature range is 40° to +100°C. A variety of heatsinks are offered for extended temperature operation. The converters offer output voltage trim and logic on/off. Protection features include volt-seconds clamp and over voltage protection, thermal shutdown, pulse by pulse current limiting and short circuit frequency foldback. All models feature a 2:1 input range, either 18 to 36 Vdc or 36 to 75 Vdc, and provide input reverse polarity protection. Output line and load regulation is typically 0.01% and 0.05% respectively. Output voltage setpoint accuracy is ±1%. (Contact 800-542-3355 for pricing and availability.)
