Overview

GST18U09-P1J is the 9V output model of this series: rated current 2.0A, typical efficiency 85%.

GST18U is a highly reliable, 18W wall-mounted style single-output green adaptor series. This product is a class Ⅱ power unit (no FG), equipped with a 2-Pin standard USA AC power plug, adopting the input range from 85VAC to 264VAC. The entire series supplies different models with output voltages ranging between 5VDC and 48VDC that can satisfy the demands for various types of consumer electronic devices. With the efficiency up to 89% and the extremely low no-load power consumption below 0.075W, GST18U is compliant with USA EISA 2007/DoE and Canada NRCAN. The supreme feature allows the adaptor to save the energy when it is either under the operating mode or the standby mode. The entire series utilizes the 94V-0 flame retardant plastic case, providing the double insulation that effectively prevents electrical shock. GST18U is certified for the international safety regulations.

Test conditions and notes8
  1. 1.All parameters are specified at 115VAC 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 )
