NOTES

(1)

Measured at Full Load.

(2)

The remote ON/OFF control pin voltage is referenced to –Vin. The negative logic is optional.

(3)

The CC mode is Constant Current Mode and is tested at nominal input voltage.

(4)

1. The iron base-plate dimension is 19” x 3.5” x 0.063” (The height is EIA standard 2U)

2. The heat-sink is optional and P/N is 7G-0058A-F

(5)

The standard module meets EMI Class A without external components.

(6)

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 KY 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.
