Test conditions and notes9

1. All parameters are specified at 230VAC input, rated load, 25℃ 70% RH ambient.
2. DC voltage: The output voltage set at point measure by plug terminal & 50% load.
3. Ripple & noise are measured at 20MHz by using a 12" twisted pair terminated with a 0.1μF & 47μF capacitor.
4. Tolerance: includes set up tolerance, line regulation, load regulation.
5. Line regulation is measured from low line to high line at rated load.
6. Length of set up time is measured at first cold start. Turning ON/OFF the power supply may lead to increase of the set up time.
7. Derating may be needed under low input voltage. Please check the derating curve for more details.
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. The power supply is considered as an independent unit, but the final equipment still need to re-confirm that the whole system complies with the 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 output does the Mean Well GST220A24-R7B provide?

This model is a 24V AC/DC power adaptor rated at 221W with a rated current of 9.2A. It is designed for applications that need a higher-power 24V DC source in an external adaptor format.

What kinds of equipment is the GST220A24-R7B commonly suited for?

The GST220A24-R7B is generally suited to commercial and industrial equipment that requires a 24V DC supply and up to 221W of output capacity. Buyers often choose this type of external power adaptor when they want a high-power external unit rather than an internal power supply.

Can this power supply be used in demanding temperature conditions?

Yes. The GST220A24-R7B has a specified working temperature range of -30°C to +70°C, with output derating required at higher ambient temperatures (see the derating curve). That makes it suitable for environments where wide temperature tolerance is an important selection factor.

What connector version is included on the GST220A24-R7B?

This specific version uses the R7B standard DC plug, a 4-pin DIN connector (KYCON KPPX-4P equivalent). That detail matters because GST220A models can be ordered with different optional output plugs, so the connector version should match the equipment requirement.

What protection and efficiency features does the GST220A24-R7B include?

The unit includes overload, over-voltage, and over-temperature protection. It also offers a typical efficiency of 93.5% and a typical power factor above 0.91 at 230VAC (above 0.98 at 115VAC), which makes it a strong fit for buyers prioritizing energy efficiency in a high-power adaptor.

What input range does the GST220A24-R7B support?

The GST220A24-R7B accepts a universal AC input range of 85 to 264VAC and also supports 120 to 370VDC input. This broad input range makes it suitable for buyers sourcing one model for use across different mains power environments.
