OUTPUT VOLTAGE ADJUSTMENT LOCATIONS

APPLICATIONS INFORMATION

1. Each output can deliver its rated current but Total Output Power must not exceed 400W.

2. Generally, adequate cooling is provided when semiconductor case temperatures do not

exceed 70

C rise and transformer temperature does not exceed 60C rise at any specified

ambient temperature.

3. Sufficient area must be provided around power supply to allow natural movement of air to

develop in convection-cooled applications.

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.

5. Minimum load is not required for reliable operation; however, a 5% load may be required on

Output 1 when loading Outputs 2, 3 or 4 to full rated current.

6. Peak-to-Peak Output Ripple and Noise is measured directly at the output terminals, without

the use of the probe ground lead or retractable tip (tip-and-barrel method), 20 MHz.

7. This product was type-tested and safety-certified using the dielectric strength test voltages

listed in Table 6 of IEC60601-1:2005. In consideration of clause 8.8.3, care must be taken to

ensure that the voltage applied to a reinforced insulation does not overstress different types

and levels of insulation. Primary and secondary-to-ground capacitors may need to be

disconnected prior to performing a dielectric strength type test on the power supply or the end

product. It is highly recommended that the DC test voltage listed in DVB.1, annex DVB of

UL60601-1 1ST Edition are not exceeded during a production-line dielectric strength test of the

assembled end product. Please consult factory for further information.

8. 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.

9. Remote-Sense terminals may be used to compensate for cable losses up to 250mV,

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. Maximum screw penetration into bottom chassis mounting holes is 0.100 inches. Maximum

screw penetration into side chassis mounting holes is 0.188 inches.

11. To comply with emissions specifications, all four mounting hole pads must be electrically

connected to a common metal chassis. Chassis/cover option is recommended. Refer to

Operating Instructions for additional information.

12. Common RF shielding precautions may need to be taken to assure emissions compliance.

Refer to Operating Instructions for additional information.

13. Power Fail (AC-Good) feature provides a logic-low warning signal from an open collector

transistor output 10-15ms prior to loss of output from AC failure, 5V/10mA (4001:3.3V/10mA).

14. 300LFM minimum of airflow must be maintained one inch above all points of top-side

components or cover when forced-air cooling is required.

15. Outputs 2, 3 and 4 are adjustable from -10% of lowest voltage rating to +10% of highest

voltage rating.

16. RE/SB Option enables all outputs with a P5-4 to P5-2 switch closure, 6V Max./50mA.

17. Output 2, 3 and 4 Inhibit feature shuts down only that output with a P6-1 to P6-2 switch

closure, 45V Max.
