DESCRIPTION
The DCMCW60 series of isolated DC/DC power converters provides 60 Watts of continuous output power in a standard
2.40” x 2.28” x 0.5” half-brick package. This series consists of 5V, 12V, and 24VDC single output models with 4:1 input
voltage ranges of 9-36VDC or 18~75VDC. Some features include high efficiency up to 86%, remote on/off, adjustable
output voltage, 1500VDC I/O isolation, -55°C~+95°C operating temperature range (with derating), and five-sided
shielding. The DCMCW60 series is RoHS compliant and has short circuit, over load, over voltage, and over temperature
protection. These converters are best suited for use in battery operated equipment, measurement equipment, telecom,
wireless networks, industry control systems, military/defense applications and anywhere where isolated, tightly regulated
voltages and compact size are required.

REMOTE SENSE APPLICATION CIRCUIT
The Remote Sense function is used to compensate for the voltage drop incurred when the load is located physically
far away from the DC/DC converter providing its power. The remote sense pins are connected as close to the load
as possible. The DC/DC converter’s regulation specifications are maintained across the points where the remote
sense wires are connected at the load. This will remove the effect of the voltage drop caused by the resistance of
the wires used to conduct the power from the DC/DC converter to the load. This is represented by RCL1 and RCL2.
With the use of remote sense, the effects of RCL1 and RCL2 are eliminated.
If the Remote Sense function is not used, the +Sense has to be connected to +Vout and the -Sense has to be
connected to -Vout as close to the DC/DC converter as possible.

EXTERNAL OUTPUT TRIM
The output is adjustable ±10% of rated output voltage. To trim the output voltage up, place the trim resistor
between the Trim and -Vo pins. To trim the output voltage down, place the trim resistor between the Trim and +Vo
pins.
