NOTE

1. All parameters NOT specially mentioned are measured at 230VAC input, rated load এবং 25℃ এর ambient তাপমাত্রা.

2. Ripple & শব্দ are measured at 20মেগাহার্টজ এর bandwidth দ্বারা using a 12″ twisted pair-wire terminated with a 0.1uf & 47uf parallel capacitor.

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

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

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

6. Length এর set up time is measured at cold first start. Turning ON/OFF দ্য power supply very quickly may lead থেকে increase এর দ্য set up

time.

7.দ 150% peak load capability is built in for up থেকে 1 দ্বিতীয় for 12~48V.LRS-350 will enter hiccup মোড if দ্য peak load is delivered

for over 1 দ্বিতীয় এবং will recover once it resumes থেকে দ্য rated current level(115VAC/230VAC).

8. দ ambient তাপমাত্রা derating এর 5℃/1000m is needed for operating

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

these EMC tests, please refer থেকে EMI testing এর component power supplies.
