1. Sufficient area must be provided around power supply to allow natural movement of air
to develop in convection cooled applications.
2. 300 linear feet per minute (minimum) of airflow must be maintained along all outside
surfaces of exposed heatsinks or chassis. See recommended air flow diagram as a
guideline.
3. Generally, adequate cooling is provided when semiconductor case temperatures do not
exceed 75' C rise and transformer temperature does not exceed 80' C rise at any
specified ambient temperature.
4. This product is intended for use as a professionally installed component within
information technology, industrial and medical equipment and is not intended for stand
alone operation. Common RF shielding precautions may need to be taken to assure
emissions compliance. Refer to operating instructions for additional information.
5. This product includes only one fuse in the input circuit. In consideration of clause 57.6
of UL 60601-1, a second fuse may be required in the end product.
6. Low forward voltage drop oring diodes must be used in all load sharing applications in
2.5 throuah 15 Volt models. Orina diodes must be used on 24 throuah 48 Volt models
used in f< tolerant applicationslbut are optional in power boosting applications. Oring
diode power dissipation must be subtracted from the maximum output power rating of
each model.
7. Current carrying conductors in load sharing applications must be short and symmetrical.
Remote sense conductors should be a twisted pair. The use of an appropriately rated
low impedance capacitor across the load will increase noise immunity.
8. Refer to Load Share Evaluation Board data sheet (page 58) for additional load share
applications information.
9. Remote sense terminals may be used to compensate for cable losses up to 400 mV
depending on model. The use of a twisted pair, decoupling capacitors and an
appropriately rated low impedance capacitor connected across the load will increase
noise immunity.
10. A load equal to Soh rated output power must be maintained when using standby power
option. An external electrolytic capacitor across standby power output may be used to
improve transient response.
11. Peak to peak output ripple and noise is measured directly at the output terminals of the
power supply, without the use of the probe ground lead or retractable tip, 20 MHz
bandwidth.
12. This product was type tested and safety certified using the dielectric strength test voltages
listed in Table V of UL 60601-1. In consideration of Clause 20.49, care must be taken to
insure that the voltage applied to a reinforced insulation does not overstress basic
insulation. Secondary to ground capacitors may need to be removed prior to performing
a dielectric strength type test on the end product. It is highly recommended that the DC
test voltages listed in DVB.1, Annex DVB are not exceeded during a production-line
dielectric strength test of the assembled end product. Please consult factory for further
information.
13. This power supply has been safety approved and final tested using a DC dielectric
strength test. Please consult factory before performing an AC dielectric strength test.
14. ~ a x i m u mscrew penetration into bottom chassis mounting holes is .I00 inches.
15. Maximum screw ~enetration side chassis mounting holes is ,150 inches.
into
16. To comply with emissions specifications, all five mounting hole pads must be electrically
connected to a common metal chassis. Chassis/cover option recommended and should
be grounded.
