PSRL0402M Series

400 Watt with Airflow

Single Output Medical Approved

AC/DC Medical Power Supply with Active PFC

SPECIFICATIONS (CONTINUED)

GENERAL SPECIFICATIONS (CONTINUED)

Grounding Test

Apply 40A from ground pin to the earthed connection point. Max allowable resistance is 0.1 ohm.

Current Sharing

Designated as CSH on the CN3, optional single wired forced current sharing function and parallel up to 4

units within 10% accuracy at full load.

Current Monitor

Designated as CMN on the CN3 for current sense for a 0.5V to 3VDC to represent 0% to 100% output current.

Margin

Designated as MAG on the CN3 providing 50% of output voltage remote adjustment by applying 0.4 ~ 5V

signal on MAG.

AC Fail (optional)

Designated as ACF on the CN3 to monitor the input voltage, when input goes under 80 ±5VAC the signal will

go low (0) and then go high (+5V) once reappears over 86VAC.

LED Display

Bi-color green LED in front panel (E Type only). Any protection occurred or RSW applied low signal will emit

orange.

NOTES

1. PSRL0402M Series is designated as PSRL0402Mx-yz where x can be blank (U-chassis), C (U-chassis with top cover), or

E (Enclosed with side built-in fan), y can be 03, 05, 12, 18, 24, 36, or 48 for output voltage, z can be blank or I where I

denote forced current sharing option (OR-ring diode). See PSRL0402M-I Series for forced current sharing.

2. PSRL0402MU Series: 400W max. with 23CFM airflow or 250W max. under convection cooling; (Option: Top Cover)

3. PSRL0402ME Series: 400W max. with built-in fan flow.

4. All output ranges are covered in agency certification and the preset voltage will be set as standard models. If any request

is not standard output, please contact us prior to ordering.

5. Providing peak power to 700W within 500uS for all models, longer duty duration need contact manufacture.

6. 1% minimum load is required to maintain the ripple and regulation.

7. Output is fully isolated.
