The Calex MH series are 30 Watt DC/DC converters
in a .6” x 2” case with a 2: and 4: input ratio. The
input voltage range is 8 to 36 or 9 to 36 VDC for 24 Volt
models and 36 to 75 or 8 to 75 for 48 Volt models.
The units are filled with a compound which allows them
to withstand a normal water wash after being soldered to
a PC board.
Description
Default ON/OFF logic is positive. Default case connected to -Vin.
Options:
Add
(-N) to the model number to order negative ON/OFF logic.
(ie. 24S5.600MH-N, 24S5.6000MHW-N)
Add
(-O) to the model number to order case connected to -Vout
(ie. 24S5.6000MH-O, 24S5.6000MHW-O)
Add
(-NO) to the model number to order negative ON/OFF logic and case
connected to -Vout (ie. 24S5.600MH-NO, 24S5.6000MHW-NO)
