Test conditions and notes9

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. A-type only.
6. 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.
7. The power supply is considered as a component that will be operated in combination with final equipment. Since EMC performance will be affected by the complete installation, the final equipment manufacturers must re-qualify EMC Directive on the complete installation again. (as available on https://www.meanwell.com//Upload/PDF/EMI_statement_en.pdf)
8. 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).
9. The water protection level test for the IP68 rating is performed 1000mm below the surface of the water for 1 month.

FAQ

Can I use the HEP-320-24A for a 24V industrial control panel with PLCs, HMIs, and sensors?

Yes, this model is a constant-voltage 24V supply rated for 320.16W and 13.34A, which fits 24VDC industrial control systems that stay within those limits. Its 90-264VAC input (277VAC operational) also helps in facilities with different AC supply ranges. The fanless design and 10G vibration rating suit harsher industrial environments than a basic enclosed supply.

Is this power supply suitable for 24V embedded or edge computing equipment in industrial enclosures?

It can be a fit for 24V embedded systems that require stable constant-voltage output and draw no more than 13.34A or 320.16W. The fanless design reduces moving parts, and the operating range of -55°C to +70°C supports demanding temperature conditions. Its UL62368-1, IEC62368-1, and EAC TP TC 004 approvals may also matter in regulated equipment builds.

Can the HEP-320-24A be used for 24V automation equipment in dusty or washdown-prone areas?

It is built for harsh environments, with an IP65 water-resistant enclosure. That makes it more suitable for exposed automation applications than an open-frame supply, especially where dust or water spray is a concern. The stated operating temperature is -55°C to +70°C.

Is the HEP-320-24A suitable for outdoor or unconditioned locations?

This version is rated IP65, so it is water-resistant and intended for harsher indoor or sheltered outdoor use rather than full submersion exposure. Its operating temperature range of -55°C to +70°C supports very cold and very hot environments. Buyers needing a higher ingress rating may compare it with IP68 variants in the series.

How does the HEP-320-24A compare with other HEP-320 voltage options?

Within the HEP-320 range, the main sibling outputs are 264W at 12V 22A for HEP-320-12 and HEP-320-12A, 285W at 15V 19A for HEP-320-15 and HEP-320-15A, 320.16W at 24V 13.34A for HEP-320-24 and HEP-320-24A, 320.4W at 36V 8.9A for HEP-320-36 and HEP-320-36A, 321.6W at 48V 6.7A for HEP-320-48 and HEP-320-48A, and 321.3W at 54V 5.95A for HEP-320-54 and HEP-320-54A. The key selection difference is output voltage, with output current changing accordingly across the same general power class.
