Notes

1

Free air convection. Maximum continuous output power not to exceed 175 W. 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

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 standalone product.

7

5 V sb (standby) output is available whenever DC input is present, regardless of remote ON/OFF signal status. 12 V (fan) present when main output is present.

8

The ‘J’ suffix indicates that these parts are Pb-free (RoHS 6/6) compliant.
