Test conditions and notes10

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 derating curve and Static characteristics for more details.
5. Without water or fan cooling to provide adequate heat dissipation, OTP might be triggered if trimming output voltage by PV signal toward upper or bottom limits of nominal voltage. Under such condition, enhanced cooling on PSU is highly recommended.
6. PV/PC function when users are not operating on PMBus. SVR functions when users are neither operation on PMBus nor using PV/PC.
7. Output will shut down after O/P voltage is below < 80% of Vset for 5 sec, re-power on to recover.
8. 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 600mm*900mm 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)
9. 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).
10. The efficiency is measured at 75% load.

FAQ

Can I use the PHP-3500-24 for a high-current 24V industrial DC bus?

Yes, this model is built for very large 24V constant-voltage loads. It is rated at 3480W with 24V output and 145A output current, which fits heavy industrial power distribution, automation, or test systems designed around a 24V bus.

Is the PHP-3500-24 appropriate for factory test racks or burn-in systems that need programmable 24V output?

It can be a strong fit for that use case because the output voltage and constant current level are programmable. With 3480W at 24V and 145A, it is sized for high-load industrial validation or production equipment rather than light-duty control panels.

Can the PHP-3500-24 support large automation systems that need more than one high-power 24V supply?

Yes, the series supports active current sharing up to 14000W in a 3+1 arrangement. That makes this 3480W, 24V, 145A model relevant when a larger 24V power architecture has to be expanded beyond a single supply.

Is the PHP-3500-24 suitable where fan noise or airflow limits are a concern?

Yes, the unit has no built-in fan: it is a fanless design cooled by conduction through its baseplate, mounted on an aluminum plate or a water cold plate (external fans are an optional alternative). The low-profile 60 mm height (72 mm with the water-cooling plate) can also help in dense industrial equipment layouts.

Can the PHP-3500-24 be used outdoors or in demanding temperature conditions?

The working temperature range is -30°C to +70°C measured at the baseplate, with load derating at higher temperatures according to the derating curve, so it can cover wide temperature conditions. However, no IP rating is listed in the supplied specs, so outdoor exposure should not be assumed without a protective enclosure.

How does the PHP-3500-24 compare with the other PHP-3500 models?

The PHP-3500 series has two output voltages: this PHP-3500-24 at 3480W 24V 145A (95% typical efficiency) and the PHP-3500-48 at 3504W 48V 73A (96% typical efficiency). Each comes as a standard PMBus version or a CAN-suffix CANBus version, and an optional cold plate (ordering no. PGG1WHS-656) is available for water cooling.
