DESCRIPTION
The DCW150 and DCWD150 series of DC/DC converters provides up to 200 watts of output power. This
series consists of single output models with a wide 4:1 input voltage range. Each model in this series
features an adjustable output voltage, constant current mode output limit, and 2250VDC input to output
isolation. The models are also protected against over voltage, over load, short circuit, over temperature,
and under voltage conditions and are compliant to both RoHS and REACH. The DCW150 and DCWD150
series are CE marked, have UL60950-1, EN60950-1 and IEC60950-1 safety approvals, and meet
EN50155 and EN45545-2 railway standards.

NOTES
Measured at Full Load.
The remote ON/OFF control pin voltage is referenced to –Vin. The negative logic is optional.
This product is Listed to applicable standards and requirements by UL.
An external input filter capacitor is required if the module has to meet EN61000-4-4 and EN61000-4-5. We suggest the following:
DCW(D)150-24Sxx: Nippon chemi-con KY series, 470µF/50V
DCW(D)150-48Sxx: Nippon chemi-con KY series, 220µF/100V
DCW(D)150-110Sxx: Nippon chemi-con KXJ series, 150µF/200V
CAUTION:
This power module is not internally fused; an input line fuse must always be used. If the load has sourcing capability (ex. Battery or super
capacitor), an output line fuse must always be used.
*Due
to advances in technology, specifications subject to change without notice.

DESCRIPTION
In normal operation. The output current is shown in data
sheet.
If the output load current are over rating, the output current
will keep in a constant value and output voltage will fall
If the output resistance becomes short, it will operate in
hiccup protection
CONDITION
Resistance Load > Vout/Iout (CC Point)

Vout < 8.0V (typ.) to Output Short
DCW(D)xxS48-150:
Vout <13V (typ.) to Output Short
FUSE CONSIDERATION
This power module is not internally fused. An input line fuse must always be used.
This encapsulated power module can be used in a wide variety of applications, ranging from simple stand-alone operation to an
integrated part of sophisticated power architecture.
To maximum flexibility, internal fusing is not included; however, to achieve maximum safety and system protection, always use an input
line fuse.
The suggested input line fuse is below:
