Free air convection. Maximum continuous output power not to exceed 175 W.
Refer to Figure 1 for the derating curve.
200 LFM (250 LFM with cover) forced air cooling from the longer side.
Maximum continuous output power not to exceed 250 W.
Figure 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.
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.
Mechanical Drawing
No 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.

This product is only for inclusion by professional installers within other
equipment and must not be operated as a stand alone product.

Three orthogonal axes, random vibration 10 minutes for each axes, 2.4 G
8
5 Vsb (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.
