Test conditions and notes6
  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 0.1μF & 47μF parallel capacitor.
  3. 3. Tolerance : includes set up tolerance, line regulation and load regulation.
  4. 4. The power supply is considered a component which will be installed into a final equipment. The final equipment must be re-confirmed that it still meets EMC directives. (as available on https://www.meanwell.com//Upload/PDF/EMI_statement_en.pdf )
  5. 5. Derating may be needed under low input voltages. Please check the derating curve for more details.
  6. 6. 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 EPP-100-24 for a 24V PLC panel, sensor bank, or automation controller?

Yes, if the equipment requires constant 24V and the total load remains within 76.8W and 3.2A with convection cooling, or 100.8W and 4.2A with a 20CFM fan. That makes it a practical fit for many 24V industrial control and sensing applications.

Is the EPP-100-24 suitable for 24V embedded or OEM equipment inside a compact enclosure?

It can fit 24V OEM and embedded equipment that draws no more than 3.2A (4.2A with a 20CFM fan) from a constant-voltage source. The 101.6 x 50.8 x 29.0 mm footprint is useful where internal mounting space is tight.

Can this model power 24V HMI equipment or industrial communication hardware?

It is appropriate for 24V control and interface devices as long as the combined load stays within 76.8W (100.8W with a 20CFM fan). Buyers should size the system against the 3.2A convection rating, or 4.2A with a 20CFM fan.

Would the EPP-100-24 work for a 24V test fixture or machine subassembly?

Yes, for fixtures or subassemblies that need a regulated 24V output and do not exceed 76.8W or 3.2A with convection cooling (100.8W or 4.2A with a 20CFM fan). The 90-264VAC input can also simplify use across different AC supply conditions.

Can the EPP-100-24 be used where temperature swings are expected?

The published operating temperature range is -30C to +70C, with output derating at higher temperatures (see the derating curve). No IP rating is shown in the provided specs, so temperature capability is stated, but direct outdoor exposure or wet-area suitability is not confirmed here.
