Product Datasheet Download MEAN WELL GST36B Datasheet (PDF) The GST36B section is on PDF pages 41, 42, 43, 44, 45. Refer to the complete mechanical drawings and notes when planning installation. Model and Output Complete model GST36B05-P1J. Series and format GST36B single-output desktop AC/DC adapter; Class II without FG. Output voltage 5 VDC. Rated current / operating range 4.3 A rated; 0–4.3 A range. Rated output power, maximum 21.5 W, subject to input and temperature derating. Ripple and noise, maximum 90 mVp-p. Voltage tolerance / load regulation ±5.0% / ±5.0%. Line regulation ±1.0%. Efficiency, typical 82%. Model code GST36B identifies the series and AC-input format; 05 identifies the 5 V output; P1J identifies the standard DC plug. Choose the load to stay within the voltage, current and maximum-power ratings together. The output-voltage setting is measured at the DC plug terminal with 50% load. Input, Timing and Energy AC input 85–264 VAC; 47–63 Hz. AC connection IEC320-C8 two-pole AC inlet. Input current 0.8 A at 115 VAC; 0.45 A at 230 VAC. Cold-start inrush, maximum 35 A at 115 VAC; 70 A at 230 VAC. Leakage current, maximum 0.25 mA at 240 VAC. Start-up and hold-up At full load: 230 VAC, 1000 / 30 / 50 ms; 115 VAC, 1500 / 30 / 13 ms (set-up / rise / hold-up). No-load power consumption <0.075 W. Energy efficiency Level VI; EISA 2007/DoE, NRCan, Korea K-MEPS, AU/NZ MEPS, EU ErP and CoC Version 5. Select a suitable mains lead for the C8 inlet and the local outlet. Confirm AC-cord supply with the order; the series datasheet does not specify a supplied mains lead. Protection Short circuit / overload 110–150% of rated output power; hiccup mode with automatic recovery after removal of the fault. Overvoltage 110–140% of rated output voltage; zener-diode clamp. Cooling and Environment Working ambient −30 to +70°C, subject to the model-specific derating curve. Temperature derating Full load through 50°C, falling to 50% at 70°C. Operation in the −30 to −20°C portion is specified for 230 VAC input only. Input-voltage curve, 60 Hz 85% load at 85 VAC, rising to 100% at 100 VAC and remaining at 100% through 264 VAC. Operating humidity 20–90% RH, non-condensing. Storage −40 to +85°C; 10–95% RH, non-condensing. Temperature coefficient ±0.03%/°C over 0–50°C. Vibration 10–500 Hz, 2 G; 10 minutes per cycle and 60 minutes along each X, Y and Z axis. Use the temperature and input-voltage limits together.

  MEAN WELL GST25B series: Desktop AC/DC Power Adapter - GST25B15-P1J

  MEAN WELL GST25B15-P1J is a single-output desktop AC/DC power adapter rated at 15 V, 1.66 A and 25 W maximum. It uses two-pole IEC 320-C8 AC inlet and a center-positive P1J DC connector. Class II, double-insulated, without FG. Apply the specified temperature and low-input-voltage derating. Product Datasheet Download MEAN WELL GST25B Datasheet (PDF) The GST25B section is on PDF pages 26, 27, 28, 29, 30. Refer to the complete mechanical drawings and notes when planning installation. Model-Specific DC Output Complete order number GST25B15-P1J. Safety model number GST25B15. DC output voltage 15 V. Rated output current 1.66 A. Output current range 0–1.66 A. Maximum rated output power 25 W, subject to input-voltage and ambient-temperature derating. Maximum ripple and noise 100 mVp-p. Voltage tolerance ±3.0%. Line regulation ±1.0%. Load regulation ±3.0%. Typical efficiency 87%. AC Input, Class and Timing AC input range 85–264 VAC, 47–63 Hz. AC connection Two-pole IEC 320-C8 AC inlet. Electrical class Class II, double-insulated, without FG.
