ARTESYN
NLP250 MEDICAL
SERIES
Single Output
Advanced Energy's Artesyn NLP250-M series of enclosed
medical AC-DC power supplies comprises two single
output models, providing standard voltages of 12 V or
24 V. Both models also provide 5 V standby and 12 V fan
outputs. They accept a universal input of 85–264 Vac and
have a low safety ground leakage current. The main output
is compatible with systems that implement distributed
power and point-of-load (POL) architectures. It can also be
used to power electromechanical devices such as relays,
motors and pumps. Featuring a thermally efficient U-channel
construction that is less than 1U high, the enclosed versions
of NLP250-M power supplies can deliver up to 250 watts
when cooled by 250 LFM of forced air.

Notes
1. Free air convection. Maximum continuous output power not to exceed 175W. Refer to Figure 1 for the derating curve.
2. 200 LFM (250 LFM with cover) forced air cooling from the longer side. Maximum continuous output power not to exceed 250 W.
3. F igure is peak-to-peak for room temperature rating. Output noise measurements are made across a 20 MHz bandwidth using a 6 inch twisted pair, terminated with a 10 µF tantalum
capacitor and a 0.1 µF ceramic capacitor.
4. CAUTION: Allow a minimum of 1 second after disconnecting line power when making thermal measurements. For optimum reliability no part of the heatsink should exceed 115 °C
and no semi-conductor case temperature should exceed 120 °C.
5. N
o external filtering required during conducted emissions testing but some applications may require additional filtering to achieve system compliance. Compliance with radiated
EMI specifications may require mounting in a suitable enclosure.
6. This product is only for inclusion by professional installers within other equipment and must not be operated as a stand alone product.
7. Three orthogonal axes, random vibration 10 minutes for each axes, 2.4 G
8. 5 V sb (standby) output is available whenever AC is present, regardless of remote ON/OFF signal status. 12 V (fan) present when main output is present.
9. The ‘J’ suffix indicates that these parts are Pb-free (RoHS 6/6) compliant. “CJ” suffix indicates covered RoHS version.
