75 Watt Triple Output - HE Series
Calex Mfg. Co., Inc. announces the availability of the HE Series
75 Watt triple output DC/DC converters. The HE triple output
series offers a primary output of either 3.3VDC or 5VDC and
auxiliary outputs of either +/-12VDC or +/-15VDC. The 5V
output is rated at up to 15 Amps and the 3.3V output is rated at
up to 20 Amps. The auxiliary outputs are rated at +/-2 Amps.
All models provide up to 75 Watts of output power giving
the designer a great deal of flexibility when loading the three
outputs. The HE Triple is isolated input to output providing a
cost effective, compact solution for powering logic and analog
circuitry.
The HE series is housed in an industry standard 1/2 brick case. All models are fully encapsulated for
rugged durability in harsh industrial and military COTS applications. The operating temperature range
for the HE triple is -40 to +100C. Calex offers a variety of heatsinks for extended temperature operation.
The MTBF is over 1M hours. UL approvals are pending. The HE triple can be ordered with an optional
mounting kit that provides screw terminal connections. All models are backed by Calex's Five Year
Warranty.
The HE triple provides output voltage trim and logic ON/OFF. In the OFF state the idle current is only
2 mADC. Positive and negative logic is available. 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 or 36 to 75VDC. All models provide input
reverse polarity protection. Output line and load regulation is typically 0.01% and 0.05% respectively.
Output voltage setpoint accuracy is +/-1%.
