NOTE

1. All parameters NOT specially mentioned are measured at 230VAC input, rated load และ 25℃ ของ ambient อุณหภูมิ.

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

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

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

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

6. Length ของ set up time is measured at cold first start. Turning ON/OFF ที่ power supply very quickly may lead ถึง increase ของ ที่ set up

time.

7.ที่ 150% peak load capability is built ใน for up ถึง 1 ที่สอง for 12~48V.LRS-350 will enter hiccup mode if ที่ peak load is delivered

for over 1 ที่สอง และ will recover once it resumes ถึง ที่ rated current level(115VAC/230VAC).

8. ที่ ambient อุณหภูมิ derating ของ 5℃/1000m is needed for operating

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

these EMC tests, please refer ถึง EMI testing ของ component power supplies.
