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-600-42 for 42V automation equipment?

Yes, this unit delivers 42V constant voltage output with a 600.6W and 14.3A rating. It is appropriate for 42V automation equipment that requires a high-power DC source within those output limits.

Is the HEP-600-42 suitable for 42V DC bus applications in industrial systems?

It can be used where the system is designed around a 42V constant voltage bus and the total load stays at or below 14.3A and 600.6W. The wide 90-264VAC input range (277VAC operational) also helps in facilities with different AC supply standards.

Can this model power 42V control panels or embedded industrial electronics?

Yes, it is a fit for 42V control panels and embedded equipment that need a constant voltage supply. Its 10G vibration rating and -40°C to +70°C operating range (with derating) are useful in industrial applications where durability matters.

Is the HEP-600-42 designed for severe environmental conditions?

Yes, it is specified as a power supply for harsh environments and operates from -40°C to +70°C (with derating per the derating curve) at 20-95% RH non-condensing. The supply is also specified to withstand 10G vibration, which supports use in harsh industrial environments.

How does the HEP-600-42 fit within the HEP-600 voltage range?

The HEP-600 series spans 12V 480W 40A, 15V 540W 36A, 20V 560W 28A, 24V 600W 25A, 30V 600W 20A, 36V 601.2W 16.7A, 42V 600.6W 14.3A, 48V 600W 12.5A, and 54V 604.8W 11.2A.
