NOTE

1. All parameters NOT specially mentioned are measured at 230VAC input, rated load en 25℃ van ambient temperature.

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

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

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

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

6. Length van set up time is measured at cold first start. Turning ON/OFF die power supply very quickly may lead na increase van die set up

time.

7.Die 150% peak load capability is built in for up na 1 sekonde for 12~48V.LRS-350 will enter hiccup manier if die peak load is delivered

for over 1 sekonde en will recover once it resumes na die rated current level(115VAC/230VAC).

8. Die ambient temperature derating van 5℃/1000m is needed for operating

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

these EMC tests, please refer na EMI testing van component power supplies.
