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 is the input and output range of the Mean Well RSDH-150-12?

This model accepts a very wide 250 to 1500VDC input range and provides a 12VDC output. It is rated for 120W total output power and 10A rated current. The output voltage is also adjustable within the stated range for this series.

What applications is the RSDH-150-12 designed for?

The RSDH-150-12 is suited to DC-DC conversion applications that need a stable 12V output from a very high and widely varying DC input. Its 250 to 1500VDC input capability makes it a strong fit for specialized industrial and high-voltage DC environments. Buyers typically consider it where conventional narrow-input converters are not suitable.

How does the RSDH-150-12 differ from a standard DC-DC converter?

Its main differentiator is the 6:1 ultra-wide 250 to 1500VDC input range, which is much broader than many standard DC-DC converters. It also withstands 1700VDC surge input for 10 seconds and uses a fanless, half encapsulated design. That combination makes it distinct for demanding DC input conditions.

Can the RSDH-150-12 operate in harsh temperature conditions?

Yes, this converter is rated for an ultra-wide operating temperature range from -40°C to +80°C. The specification notes derating above +55°C. This makes it appropriate for environments with significant temperature variation, provided the application stays within the published limits.

What protection features are included in the Mean Well RSDH-150-12?

This model includes protection for short circuit, overload, over voltage, over temperature, DC input under voltage, and DC input reverse polarity. These built-in protections help support reliability in demanding applications. The unit is also designed to withstand 1700VDC surge input for 10 seconds.

Is the RSDH-150-12 a good fit for space-constrained equipment?

It is designed with a 1U low-profile form factor and a height of 41mm, which can help in compact equipment layouts. The fanless construction also supports use where reduced maintenance and passive cooling are preferred. Buyers evaluating enclosure space often look at this model for those reasons.

What environmental and operating limits should buyers consider for this model?

In addition to its -40°C to +80°C operating range, the RSDH-150-12 is rated for operating altitudes up to 5000 meters. It uses free air convection cooling and is half encapsulated. These characteristics are relevant for industrial applications where altitude, temperature, and passive cooling matter.

What warranty is provided with the RSDH-150-12?

The Mean Well RSDH-150-12 includes a 3-year warranty. For buyers comparing industrial power products, that provides a clear baseline for expected manufacturer support. Warranty terms should still be reviewed alongside the seller's product policy.
