Test conditions and notes8

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 static characteristics for more details.
5. Length of set up time is measured at cold first start. Turning ON/OFF the power supply may lead to increase of the set up time.
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 https://www.meanwell.com//Upload/PDF/EMI_statement_en.pdf)
7. 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).
8. Some model may not have the BIS logo, please contact your MEAN WELL sales for more information.

FAQ

Can I use the HEP-600-20 for 20V industrial or embedded equipment?

Yes, it is built for constant-voltage 20V DC applications and can deliver up to 28A and 560W. That makes it suitable for industrial and embedded equipment designed specifically for a 20V supply rail.

Is the HEP-600-20 suitable for 20V automation subsystems in harsh environments?

It can fit 20V automation subsystems that need a constant-voltage supply and stay within 560W and 28A. The -40°C to +70°C operating range (with derating) and 10G vibration rating support use in rugged industrial conditions.

Can this model be used for 20V test equipment or specialized control hardware?

It is appropriate for 20V test, instrumentation, or control hardware that requires constant 20V DC and falls within the 28A output limit. The 90-264VAC input range (277VAC operational) also helps where the equipment may be deployed internationally or in facilities with varying AC input.

Is the HEP-600-20 suitable for outdoor or wet locations?

The spec sheet does not state an IP rating for this model, so confirm its suitability before installing it in outdoor or wet locations. It is specified for harsh environments, with -40°C to +70°C operation (with derating) and 20-95% RH non-condensing humidity.

How does the HEP-600-20 differ from nearby HEP-600 voltage options?

The HEP-600-20 is rated 560W at 20V and 28A. In the same family, the nearby constant-voltage options are 15V at 540W and 36A, 24V at 600W and 25A, 30V at 600W and 20A, 36V at 601.2W and 16.7A, 42V at 600.6W and 14.3A, 48V at 600W and 12.5A, and 54V at 604.8W and 11.2A.
