Certifications & ratings

IP rating

Test conditions and notes10
  1. 1. All parameters NOT specially mentioned are measured at 230VAC input, rated load and 25℃ of ambient temperature.
  2. 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. 3. Tolerance : includes set up tolerance, line regulation and load regulation.
  4. 4. Derating may be needed under low input voltages. Please check the static characteristics for more details.
  5. 5. A-Type only.
  6. 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. 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. 8. The water protection level test for the IP68 rating is performed 1000mm below the surface of the water for 1 month.
  9. 9. Refer to warranty statement.
  10. 10. 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).

FAQ

Can I use the HEP-240-24 for 24V PLCs, sensors, or automation loads?

Yes, this is a constant-voltage 24V power supply rated for 10A and 240W, which fits many 24V automation and control systems. It is intended for loads that require a stable 24V DC output and stay within those current and power limits.

Is the HEP-240-24 suitable for 24V industrial networking or embedded control systems?

It can support 24V industrial electronics, embedded controllers, and network-related equipment that are designed for constant-voltage 24V input and draw up to 10A. The 92.5% typical efficiency and 10G vibration rating are also helpful in enclosed cabinets.

Can this model be used for outdoor 24V equipment or harsh-environment installations?

The HEP-240-24 carries an IP68 rating, so it is built for strong protection against dust and water exposure in harsh environments. Its -55°C to +70°C operating temperature range also supports use where ambient conditions are unusually cold or hot.

Would the HEP-240-24 work for 24V LED, control, or DC distribution systems?

It is a fit for 24V constant-voltage systems where the combined load stays within 240W and 10A. That makes it relevant for industrial DC distribution, 24V control assemblies, and other 24V equipment that needs a rugged power source rather than a basic indoor supply.

How does the HEP-240-24 compare with other HEP-240 outputs?

In the HEP-240 series, the 12V models are 192W and 16A, the 15V models are 225W and 15A, the 24V models are 240W and 10A, the 36V models are 241.2W and 6.7A, the 48V models are 240W and 5A, and the 54V models are 240.3W and 4.45A, with each voltage available in both standard and A-suffix versions. This HEP-240-24 is the IP68 24V, 10A option, while HEP-240-24A is the IP65 version with the same electrical rating.
