NOTE

1. All parameters NOT specially mentioned are measured at 230VAC input, rated load Và 25℃ của ambient nhiệt độ.

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

3. Tolerance : includes set up tolerance, line regulation Và 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 của set up time is measured at cold first start. Turning ON/OFF các power supply very quickly may lead to increase của các set up

time.

7.các 150% peak load capability is built in for up to 1 thứ hai for 12~48V.LRS-350 will enter hiccup cách thức if các peak load is delivered

for over 1 thứ hai Và will recover once it resumes to các rated current level(115VAC/230VAC).

8. các ambient nhiệt độ derating của 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 của component power supplies.
