Test conditions and notes7

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 0.1μF & 47μF parallel capacitor.
3. Tolerance : includes set up tolerance, line regulation and load regulation.
4. Touch current was measured from primary input to DC output.
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. Heat Sink HS1,HS2,HS3 can not be shorted.
7. 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 360mm*360mm 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 )

FAQ

Can I use the RPS-75-36 for 36V automation or industrial control equipment?

Yes, if the equipment requires 36V constant voltage and draws no more than 2.1A or 75.6W. It is better matched to lighter-current 36V control loads than to higher-current 36V systems.

Is the RPS-75-36 suitable for 36V test, measurement, or instrumentation devices?

It can be used for instrumentation or measurement equipment that specifies 36V DC input and stays within the 2.1A output limit. The wide 90-264VAC input range also supports installations across different AC supply standards.

Can this model power compact medical or laboratory equipment that needs 36V DC?

Yes, for devices that require a 36V constant voltage source and consume up to 75.6W. Its medical safety approval is relevant for medical or lab designs, but the load still has to remain within the 2.1A rating.

How does the RPS-75-36 differ from other RPS-75 output versions?

The RPS-75 lineup includes 3.3V 15A 49.5W, 5V 14A 70W, 12V 6.3A 75.6W, 15V 5A 75W, 24V 3.2A 76.8W, 36V 2.1A 75.6W, and 48V 1.6A 76.8W models. The RPS-75-36 is the 36V member and is rated for 2.1A output.

Is the RPS-75-36 appropriate for outdoor or washdown environments?

The unit is specified for operation from -20°C to +70°C. It is an open-frame PCB type power supply with no IP rating, so it must be installed in a protected indoor enclosure and is not suitable for exposed outdoor or washdown locations.
