1

Free air convection. Maximum continuous output power not to exceed

175 W. Refer to Figure 1 for the derating curve.

2

200 LFM forced air cooling from the longer side. Maximum continuous

output power not to exceed 250 W.

3

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.

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

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.

6

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

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.

TSE RoHS 5/6 (non Pb-free) compliant versions may be available on

special request, please contact your local sales representative for details.
