Datasheet
XP Power ## 250 Watts - 250 W Convection-cooled - Industry Standard 3”x 5”Package - 80 VAC to 300 VAC Input - 5V Standby (optional) - <0.5W Standby Power - IT & Medical (BF) Safety Approvals - Power Fail & Inhibit Signals - 3 Year Warranty Dimensions: The universal AC input CHD250 provides 250W of convection cooled output power in a 3” x 5” industry standard package, over the temperature range -20°C to +50°C with derating to +70°C. Approved for IT and Medical and with a feature set including a 5V standby output, <0.5W input power when in standby mode, power fail and inhibit signals the CHD250 is ideal for a wide range of applications where fan cooling is not desirable. CHD250: 5.00 x 3.00 x 1.43” (115 x 76 x 36 mm) CHD250-C: 5.50 x 3.48 x 1.75” (139.7 x 88.5 x 44.4 mm) Models & Ratings |Output Voltage 1|Output Current V1<br>Standby Supply V2<br>(optional)|Standby Supply V2<br>(optional)<br>Output Power|Model Number(1,2)| |---|---|---|---| |12 V|20.8 A<br>5.0 V / 0.5 A|5.0 V / 0.5 A<br>250 W|CHD250PS12| |15 V|16.7 A<br>5.0 V / 0.5 A|5.0 V / 0.5 A<br>250 W|CHD250PS15| |24 V|10.4 A<br>5.0 V / 0.5 A|5.0 V / 0.5 A<br>250 W|CHD250PS24| |28 V|8.9 A<br>5.0 V / 0.5 A|5.0 V / 0.5 A<br>250 W|CHD250PS28| |48 V|5.2 A<br>5.0 V / 0.5 A|5.0 V / 0.5 A<br>250 W|CHD250PS48| ## ~~**Notes**~~ _1.

Due to the uncertain nature of the end application this estimated service life is based on the actual measured temperature of a key capacitors with in the product when installed by the end application. The worst case of the two figures should be taken as the indicative service life in 24/7 operation.

About Novapart
Novapart is a B2B electronic component broker specialising in stock shortages and cost reduction. We source hard-to-find parts and identify compliant alternatives across a catalogue of 410,000+ components from 500+ manufacturers.
Learn more →Stock Shortage Specialist
When a component is unavailable, discontinued or has an unacceptable lead time, we tap into our network of vetted European and Asian distributors to source what you need — without compromising on quality or traceability.
Request a quote →Compliant Alternatives
We identify pin-to-pin, electrically equivalent substitutes that meet the same certifications (RoHS, AEC-Q100, REACH) as your original specification — validated against datasheets, not just part numbers. Often at a lower cost.
