Test conditions and notes8
  1. 1.All parameters are specified at 230VAC input, rated load, 25℃ 70% RH ambient.
  2. 2.DC voltage: The output voltage set at point measure by plug terminal & 50% load.
  3. 3.Ripple & noise are measured at 20MHz by using a 12" twisted pair terminated with a 0.1μF & 47μF capacitor.
  4. 4.Tolerance: includes set up tolerance, line regulation, load regulation.
  5. 5.Line regulation is measured from low line to high line at rated load.
  6. 6.Load regulation is measured from 10% to 100% rated load.
  7. 7.Derating may be needed under low input voltage. Please check the derating curve for more details.
  8. 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 https://www.meanwell.com//Upload/PDF/EMI_statement_en.pdf )

FAQ

Can I use the GST36B12-P1J for a 12V industrial controller or HMI?

Yes, it can be used with 12V industrial controllers, HMIs, and similar electronics that require constant-voltage DC input. The supply is rated for 36W at 12V with up to 3A output current.

Is the GST36B12-P1J suitable for small 12V automation loads?

It is suitable for smaller 12V automation loads that are designed for constant-voltage operation. With 12V output and 3A available, it fits modest-power control, interface, and monitoring devices within a 36W budget.

Can this model power 12V LED strips or display lighting?

Yes, it can be used for 12V LED strips or display lighting that require a constant-voltage 12V source. The connected load should stay within 36W total, which corresponds to 3A at 12V.

Would the GST36B12-P1J work for compact 12V embedded or security electronics?

It can work for compact 12V embedded devices or other low-power electronics that need regulated 12V DC. Its small 79.0 x 54.0 x 33.0 mm housing can also help in space-constrained equipment layouts.

Is the GST36B12-P1J okay for outdoor environments?

The operating temperature range is -30C to +70C, so the unit is specified for a wide temperature window. No IP rating is listed in the provided specs, so direct outdoor exposure or wet and dusty conditions should not be assumed.
