Test conditions and notes10

1. All parameters NOT specially mentioned are measured at 230VAC input, rated load and 25℃ of ambient temperature.
2. The rated power includes 5Vsb @ 0.6A.
3. The rated power includes 5Vsb @ 0.8A.
4. Ripple & noise are measured at 20MHz of bandwidth by using a 12" twisted pair-wire terminated with a 0.1μF & 47μF parallel capacitor.
5. Tolerance : includes set up tolerance, line regulation and load regulation.
6. Derating may be needed under low input voltages. Please check the derating curve for more details.
7. Touch current was measured from primary input to DC output.
8. 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).
9. HS1,HS2 & HS3 can not be shorted.
10. 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-160-48 for a 48V industrial control or automation system?

Yes, this model is a constant-voltage 48V supply rated for 2.3A and 113.4W, which fits 48V industrial control loads that need a stable DC bus. It is better suited to protected equipment inside industrial or automation enclosures than to exposed field use because no IP rating is listed.

Is the RPS-160-48 suitable for 48V embedded or telecom-style electronics?

It can be a fit for 48V embedded and communications equipment that operates within a 2.3A load limit. The wide 90-264VAC input also helps when the same product may be used across different AC mains environments.

Can this power supply be used in medical electronic equipment?

Yes, this model is a medical power supply with 2xMOPP isolation, approved to IEC/EN 60601-1 and ANSI/AAMI ES60601-1. It is suitable for BF-rated patient contact medical systems, such as monitors and dialysis machines.

Would the RPS-160-48 work for a 48V lab, test, or instrumentation system?

It is appropriate for 48V instrumentation or bench equipment that needs constant-voltage output up to 2.3A. The compact 127.0 x 76.2 x 34.6 mm form factor can also help where internal space is limited.

Can the RPS-160-48 be used outdoors or in harsh environments?

The operating temperature range is -20°C to +70°C, so the temperature spec covers a broad indoor operating range. However, no IP rating is listed, so it should be treated as a protected indoor power supply rather than an exposed outdoor unit.
