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.
6. Safety and EMC design refer to BS EN/EN60598-1, CNS15233, GB7000.1, FCC part18.
7. 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.
8. 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)
9. The water protection level test for the IP68 rating is performed 1000mm below the surface of the water for 1 month.
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 Mean Well HEP-100-12 for a 12V industrial control or automation system?

Yes, this model is a 12V constant voltage power supply rated for 100.08W and 8.34A output. That makes it suitable for 12V industrial control, automation, and embedded systems that need a regulated 12V DC supply within that power and current range.

Is the HEP-100-12 suitable for 12V embedded or IT equipment in harsh environments?

It can be a fit for 12V embedded and IT equipment when the load stays within 100.08W and 8.34A. The 92% typical efficiency, 10G vibration resistance, and operating range of -55°C to +70°C (with derating per the derating curve) make it appropriate for demanding environments.

Can this power supply run a 12V outdoor electronics or monitoring system?

It is designed for harsh-environment use and carries an IP68 rating, so it is suited to outdoor or exposed locations where a sealed power supply is needed. It provides 12V constant voltage output up to 8.34A and 100.08W, so the connected 12V system needs to stay within those limits.

Can the HEP-100-12 be used indoors and outdoors in very hot or very cold conditions?

Yes, the unit is rated IP68 and has an operating temperature range of -55°C to +70°C, with output derating at the temperature extremes per the derating curve. Those specs make it suitable for both indoor and outdoor environments where moisture, dust, or wide temperature swings are a concern.

How does the HEP-100-12 compare with other HEP-100 series voltage options?

The HEP-100-12 is rated 100.08W at 12V and 8.34A, and the HEP-100-12A has the same 100.08W, 12V, and 8.34A ratings. Other HEP-100 variants are HEP-100-15 and HEP-100-15A at 100.05W, 15V, 6.67A; HEP-100-24 and HEP-100-24A at 96W, 24V, 4A; and HEP-100-36 and HEP-100-36A at 95.4W, 36V, 2.65A. The remaining options are HEP-100-48 and HEP-100-48A at 96W, 48V, 2A, plus HEP-100-54 and HEP-100-54A at 95.58W, 54V, 1.77A.
