NOTE

1. All parameters NOT specially mentioned are measured at 230VAC input, rated load in 25℃ od ambient temperatura.

2. Ripple & noise are measured at 20MHz od bandwidth mimo using a 12″ twisted pair-wire terminated with a 0.1uf & 47uf parallel capacitor.

3. Tolerance : includes set up tolerance, line regulation in load regulation.

4. Line regulation is measured from low line to high line at rated load.

5. Load regulation is measured from 0% to 100% rated load.

6. Length od set up time is measured at cold first start. Turning ON/OFF the power supply very quickly may lead to increase od the set up

time.

7.The 150% peak load capability is built in for up to 1 drugi for 12~48V.LRS-350 will enter hiccup mode if the peak load is delivered

for over 1 drugi in will recover once it resumes to the rated current level(115VAC/230VAC).

8. The ambient temperatura derating od 5℃/1000m is needed for operating

altitude greater than 2000m(6500ft).EMC directives. For guidance on how to perform

these EMC tests, please refer to EMI testing od component power supplies.
