HRP 300 N3 series 300W Ultra-High Peak Power Supply

Meanwell HRP 300 N3 series is a 3oow single output AC/DC ultra-high peak power supply. This series operates at85~264VAC input voltage and offers the models with the DC output mostly demanded from the industry. Eachmodel is cooled by the built-in fan with fan ON-OFF control, working for the temperature up to 70℃.Moreover,HRP-30ON3 can provide 350% short-duration peak power for motor applications and electromechanical loadsrequiring much higher power during start-up.

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

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

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

4. Derating may be needed under low input voltages. Please check the derating curve for more details.

5. The ambient temperature derating of 3.5℃/1000m with fanless models and of 5℃/1000m with fan models for operating altitude higher than 2000m(6500ft).

6. The power supply is considered a component which will be installed into a final equipment. All the EMC tests are been executed by mounting the unit on

a 360mm*360mm metal plate with 1mm of thickness. The final equipment must be re-confirmed that it still meets EMC directives. For guidance on how to

perform these EMC tests, please refer to “EMI testing of component power supplies.” (as available on
