Test conditions and notes12

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 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 lower limits of nominal voltage. Under such condition, enhanced cooling on PSU is highly recommended.
6. In the control priority on Vout and Iout trimming, Please refer to the table on page 9.
7. Output will shut down after O/P voltage is below < 80% of Vset for 5 sec, re-power on to recover.
8. Need additional EMI filter to meet regulations of EMC conducted and radiated emission. Characteristics of EMI filter please refer to the table, Minimum Insertion Loss.
9. 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)
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).
11. The efficiency level is measured at output voltage: 133V (115V model)/ 217V (230V model)/ 333V (380V model).
12. Refer to derating curve.

FAQ

What is the Mean Well PHP-3500-115 designed for?

The PHP-3500-115 is a high-power enclosed AC-DC power supply intended for demanding industrial and OEM applications that need a 115V DC output. With a 3500W power rating and programmable output/current features, it fits systems where high output power and control flexibility matter.

What are the main electrical ratings of the PHP-3500-115?

This model is rated for 3500W with a nominal 115V DC output and 26.3A rated current. It is part of the PHP series with high-voltage output capability, and the product description also notes support for 115/230/380V DC variants within the series.

How is the PHP-3500-115 cooled?

The PHP-3500-115 uses a fanless design and is intended for water cooling or conduction cooling rather than internal fan cooling. That makes it a good fit for applications where low-profile thermal management and reduced airborne dust intake are important.

What makes the PHP-3500-115 different from a standard enclosed power supply?

This model stands out for its very high 3500W output, high-voltage 115V DC rating, slim 60mm low-profile housing, and fanless thermal design. It also adds built-in PMBus communication and programmable output settings, which are not typical on basic enclosed power supplies.

Does the PHP-3500-115 support remote monitoring or control?

Yes. The PHP-3500-115 includes built-in PMBus communication, and it also provides remote ON/OFF control plus a DC-OK active signal. Those features make it suitable for systems that need status feedback and centralized power management.

What protection features are built into the PHP-3500-115?

The PHP-3500-115 includes protection for short circuit, overload, over voltage, and over temperature conditions. These built-in protections help support use in high-power equipment where fault handling and system reliability are important.

What operating temperature range is specified for the PHP-3500-115?

This model is specified for operation from -30°C to 70°C. That wide temperature range supports use in demanding industrial environments, provided the overall system design accounts for the unit's cooling method and operating conditions.

Is the PHP-3500-115 suitable when low-profile packaging is important?

Yes. The PHP-3500-115 is described as slim and low profile, with a 60mm height, which helps when space is constrained in larger power systems. Its 4.07 kg weight and enclosed form factor also indicate it is built for substantial high-power installations rather than compact consumer devices.
