Test conditions and notes5

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. 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 http://www.meanwell.com)
5. Derating may be needed under low input voltages. Please check the derating curve for more details.

FAQ

Can I use the SP-320-27 for industrial equipment that requires 27V DC?

Yes, this model provides a constant voltage 27V output and can deliver up to 11.7A with a 315.9W power rating. It is suitable for industrial or automation loads that specifically call for 27V DC rather than another nominal voltage.

Is the SP-320-27 appropriate for a 27V control or actuator system?

It can be used where the total 27V load stays within 315.9W and 11.7A. That makes it relevant for higher-power 27V DC control equipment, actuators, or other automation hardware designed around a 27V bus.

Will the SP-320-27 work for a 27V test bench or embedded development setup?

Yes, if the equipment requires a regulated 27V DC source and total draw remains at or below 315.9W and 11.7A. The 88-264VAC input range also makes it practical for varied AC supply conditions.

Can this power supply support multiple 27V devices from one source?

It can, provided the combined demand does not exceed 315.9W or 11.7A at 27V. This allows one supply to serve several 27V loads in an industrial, automation, or lab environment when the load budget is properly matched.

Is the SP-320-27 rated for outdoor service?

The listed operating temperature range is -20°C to +65°C, but the provided specifications do not include an IP rating. Based on those specs, temperature performance is defined, while weather or direct-exposure suitability is not.

How does the SP-320-27 compare with the other SP-320 voltage options?

In the listed SP-320 family, SP-320-12 is 300W at 12V and 25A, SP-320-27 is 315.9W at 27V and 11.7A, SP-320-36 is 316.8W at 36V and 8.8A, and SP-320-48 is 321.6W at 48V and 6.7A. The series keeps a similar power class while changing voltage and output current.
