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 are the main output specifications of the Mean Well GST220A20-R7B?

The GST220A20-R7B is a 220W AC/DC power adaptor with a 20V DC output. It is rated for 11A output current, making it suitable for equipment that requires a higher-power 20V supply. This model uses the standard R7B 4-pin DIN plug (KYCON KPPX-4P equivalent).

What input voltage range does the GST220A20-R7B support?

This model accepts a universal AC input range of 85 to 264VAC and also supports 120 to 370VDC input. That wide range makes it practical for commercial and industrial use across different regions. It also offers power factor correction, with a typical power factor above 0.98 at 115VAC and above 0.91 at 230VAC.

Is the GST220A20-R7B suitable for continuous use in demanding environments?

The GST220A20-R7B is designed for operation from -30°C to +70°C, with output derating required at higher ambient temperatures (see the derating curve). It also includes protection for overload, over-voltage, and over-temperature conditions. These characteristics make it a strong fit for professional equipment operating in varied indoor environments.

What type of equipment is the GST220A20-R7B commonly used for?

This 20V, 220W adaptor is intended for devices that need a regulated 20V DC supply at up to 11A. Buyers typically consider this type of unit for higher-power commercial, industrial, or electronic equipment where an external power adaptor is preferred. Compatibility depends on the required voltage, current draw, and matching R7B plug format.

How does the GST220A20-R7B differ from lower-power 20V power supplies?

The main difference is output capacity: this model provides up to 220W and 11A at 20V, which is higher than many standard external adaptors. It is intended for loads that need more current headroom without moving to a different output voltage. It also offers a typical efficiency of 92% and a typical power factor above 0.91 at 230VAC.

What compliance and efficiency features does the GST220A20-R7B offer?

The GST220A20-R7B has a typical efficiency of 92% and a typical power factor above 0.91 at 230VAC. It is approved to multiple safety standards including UL62368-1, TUV BS EN/EN62368-1, BSMI CNS15598-1, CCC GB4943.1, and PSE J62368-1, with EMC compliance including EN55032 Class B and FCC Part 15 Class B. These certifications are relevant for buyers sourcing power supplies for regulated business applications.

What should I check to confirm compatibility with the GST220A20-R7B?

Confirm that your equipment requires 20V DC input and does not exceed 11A or 220W total power draw. You should also verify that the required DC connector matches the standard R7B 4-pin DIN plug (KYCON KPPX-4P equivalent) used on this model. The standard output cable length is about 1000mm (±50mm).
