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 is the output rating of the Mean Well GST160A48-R7B?

The GST160A48-R7B is a 160W desktop AC/DC power supply with a 48V DC output. Its rated output current is 3.34A, making it suitable for equipment that requires a regulated 48V supply within that power range.

What kind of DC output connector does this model use?

This version uses the R7B standard DC plug, a 4-pin locking DIN-type connector (KYCON KPPX-4P equivalent). Other plug types are available as options, so buyers should confirm their equipment is designed for the same mating connector.

Is the GST160A48-R7B suitable for international AC input ranges?

Yes. It accepts a universal AC input range of 85 to 264VAC, and it also supports 120 to 370VDC input. This makes it appropriate for use across regions with different standard mains voltages, provided the overall application and approvals match local requirements.

Can this power supply be used in demanding temperature environments?

The specified working temperature range is -30°C to +70°C, with load derating at higher temperatures per the derating curve. That wide range makes it a practical choice for industrial and commercial equipment that may operate in colder or hotter environments than typical office electronics.

What protection features are included in the GST160A48-R7B?

This model includes protection against overload, over voltage, and over temperature conditions. Overload and over-voltage protection both use hiccup mode, while over-temperature protection shuts down the output and requires re-powering to recover.

How energy efficient is this power supply?

The GST160A48-R7B has a typical efficiency of 94% at 230VAC input and rated load. Its typical power factor is above 0.94 at 230VAC and above 0.98 at 115VAC at full load, which helps buyers comparing energy performance.

What physical format and size does this model have?

This is a desktop-style external adaptor with an IEC320-C14 AC inlet. Its dimensions are 175 x 72 x 35 mm, and the output cable (UL2464 18AWG x 4C) is specified as 120 cm.
