Test conditions and notes6

1. All parameters NOT specially mentioned are measured at 800Vdc 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 0.1μf & 47μf parallel capacitor.
3. Tolerance : includes set up tolerance, line regulation and load regulation.
4. Derating may be needed under low input voltage. Please check the derating curve for more details.
5. 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).
6. 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. 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 )

FAQ

What applications is the Mean Well RSDH-150-48 best suited for?

The RSDH-150-48 is designed for high-voltage DC systems that need a regulated 48V output from a very wide DC input range. Its 250-1500VDC input capability makes it relevant for industrial and other specialized DC bus applications where input voltage can vary significantly. Buyers typically choose this model when they need 150W output with 48VDC at up to 3.12A.

What makes the RSDH-150-48 different from a standard DC-DC converter?

The main differentiator is its 250-1500VDC 6:1 ultra-wide input range, which is far broader than conventional DC-DC converters. This model also withstands 1700VDC surge input for 10 seconds, uses a fanless half-encapsulated design, and operates across a wide -40°C to +80°C temperature range with derating above +55°C. Those features make it a more specialized option for demanding DC input environments.

Can this converter handle fluctuating or high-voltage DC input sources?

Yes. The RSDH-150-48 is built for DC inputs from 250VDC to 1500VDC and can tolerate 1700VDC surge input for 10 seconds. That specification is a key reason to select this model when the upstream DC source is much higher than typical low-voltage converters are designed for.

Is the RSDH-150-48 suitable for harsh temperature or high-altitude environments?

This model is specified for operation from -40°C to +80°C, with derating required above +55°C. It is also rated for operating altitudes up to 5000 meters. Combined with its fanless, half-encapsulated construction, that makes it a strong candidate for demanding ambient conditions.

What output does the Mean Well RSDH-150-48 provide?

The converter provides a nominal 48VDC output with a 150W power rating and rated output current of 3.12A. Its output voltage is also adjustable within the 48-58V range. That flexibility can help when a system needs a regulated 48V class DC output with some adjustment margin.

What protection features are included on the RSDH-150-48?

The RSDH-150-48 includes protection for short circuit, overload, over voltage, over temperature, DC input under voltage, and DC input reverse polarity. These built-in protections are part of the model's design for higher-risk DC environments. Mean Well also backs this unit with a 3-year warranty.
