Test conditions and notes8
- 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.When measured between the light load (20% of rated load) and full load, the load regulation is within ±5% whereas the cross regulation is within ±15%.
- 7.Derating may be needed under low input voltages. Please check the static characteristics for more details.
- 8.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 http://www.meanwell.com)

FAQ
Can I use the GP50A13A-R1B for a 5V industrial controller or embedded board?
This model provides a 5V output rated at 4A. For control electronics or embedded hardware that need regulated 5V power within its 46.5W total rating, it fits that type of application.
Is this power supply suitable for 5V automation interfaces or logic-level equipment?
It can suit automation or logic-level loads that require 5V DC and stay within the 4A output limit. The wide 90-264VAC input also supports use in installations where AC input availability varies.
Can this model be used in older systems that need multiple rails like 5V, 12V, and -5V?
Yes, this GP50A series triple output adaptor provides 5V, 12V and -5V rails, which aligns with equipment designed around multiple DC rails. The specs list 5V at 0-4A, 12V at 0.3-2A and -5V at 0.1-0.5A with a total rated power of 46.5W, so check each rail's load, including the minimum load on 12V and -5V, before selection.
Is the GP50A13A-R1B appropriate for indoor control cabinets or panel environments?
The published operating temperature range is -20°C to +70°C, with output derating at higher ambient temperatures per the derating curve, which supports use across a broad indoor equipment environment. No IP rating is provided in the supplied specs, so the product data does not indicate direct outdoor or exposed-environment use.
What kind of electrical environment is this model designed to accept on the input side?
This power supply accepts 90-264VAC (47-63Hz) input, which is useful where equipment may be deployed across different standard AC mains ranges; derating may be needed at low input voltages. The sheet lists IEC62368-1, UL62368-1, CSA22.2, BS EN/EN62368-1 and EAC TP TC 004 safety approvals and FCC Part 15 Class B emissions.
