The MEAN WELL GST360A series is a high-reliability 360W-class AC-DC desktop single-output green adapter built into a fully enclosed, fanless plastic housing. It connects to mains through a 3-pole IEC320-C14 inlet and is a Class I power supply with protective earth. Input range is 85~264VAC or 120~370VDC, and the series covers six output voltages from 12V to 55VDC - 12V, 15V, 24V, 36V, 48V and 55V, with no 20V model - serving consumer electronic devices, telecom equipment, office equipment and industrial equipment.
What separates the GST360A from the smaller GST platforms is peak power: every model delivers roughly 1.25 times its rated power for 3 seconds - 415W on the 12V model, 425W on 15V and 450W on 24V through 55V. That headroom absorbs motor inrush and capacitive start-up loads that would otherwise force a larger, more expensive adapter. Rated power itself is not a flat 360W: 12V is 330W, 15V is 340.5W, and only the 24V, 36V, 48V and 55V models reach the full 360W.
The input stage uses active power factor correction, with power factor above 0.95 at 230VAC and above 0.98 at 115VAC at full load, drawing 3.8A at 115VAC and 2A at 230VAC. Maximum leakage current is 1.5mA at 240VAC. Withstand voltage is 3KVAC input-to-output and 2KVAC input-to-FG, with the output-to-FG path effectively shorted. Typical efficiency runs from 91% on 12V to 95% on the 48V and 55V models, meeting Efficiency Level VI with no-load consumption published as below 0.5W - the Level VI ceiling for the above-250W band, so it is compliant rather than a regression. This is an ITE product: for patient-contact medical equipment choose a 60601-1 certified adapter from the GSM series instead.
The standard output connector is voltage-dependent on this series: 12V and 15V ship with the C8P, an 8-pin MOLEX 39-01-2080 equivalent carrying four +Vo and four -Vo pins on a 27.5A / 22.7A output; 24V through 55V ship with the C6P, a 6-pin MOLEX 39-01-2060 equivalent with three +Vo and three -Vo pins. On both standard connectors the negative output is connected to AC FG, so the output is referenced to protective earth rather than floating; a floating build with -V disconnected from FG is available on special request. Protections cover short circuit, overload (135%~155% of rated power - hiccup and auto-recovery on 12~36V, shutdown and restart on 48V and 55V), over voltage (105%~135% of rated output voltage, shutdown with restart) and over temperature (shutdown with restart). The 220 x 95 x 46mm adapter weighs 1.4Kg, operates from -30C to +70C and is backed by a 3-year warranty.
Output ratings for all six GST360A models. All values measured at 230VAC input, rated load, 25C / 70%RH unless otherwise noted.
| Model | Output Voltage | Rated Current | Current Range | Rated Power (Max) | Peak Power (3s) | Efficiency (Typ.) |
|---|---|---|---|---|---|---|
| GST360A12-C8P | 12V | 27.5A | 0 ~ 27.5A | 330W | 415W | 91% |
| GST360A15-C8P | 15V | 22.7A | 0 ~ 22.7A | 340.5W | 425W | 92% |
| GST360A24-C6P | 24V | 15A | 0 ~ 15A | 360W | 450W | 93% |
| GST360A36-C6P | 36V | 10A | 0 ~ 10A | 360W | 450W | 94% |
| GST360A48-C6P | 48V | 7.5A | 0 ~ 7.5A | 360W | 450W | 95% |
| GST360A55-C6P | 55V | 6.55A | 0 ~ 6.55A | 360W | 450W | 95% |
Rated power is 330W on 12V, 340.5W on 15V, and 360W on 24V / 36V / 48V / 55V - only four of the six models reach the 360W nominal. Peak power for 3 seconds is published separately (415W / 425W / 450W) and is a transient rating, not a continuous one. The series covers six voltages and there is no 20V model; 55V is the highest output ever offered in a GST desktop adapter.

Overload protection is rated 135%~155% of rated output power across the series, but the response changes at 48V: the 12V, 15V, 24V and 36V models enter hiccup mode and recover automatically once the fault is removed, while the 48V and 55V models shut the output down and require a restart. Over-voltage protection trips at 105%~135% of rated output voltage with output shutdown and restart on every model, and over-temperature protection behaves the same way. All three are listed in the Input & Protection table below.
| Style | Type | Model | Pin Definition |

Note: the GST360A publishes two standard plugs split by voltage - C8P on 12V and 15V, C6P on 24V to 55V - and only two optional plugs, MIC4 and C4P, both restricted to 36~55V. There is no R7BF on this series, no tuning-fork 5.5mm plug and no quick-change adapter. For the 12V, 15V and 24V models no optional plug is published at all, so those voltages ship with their standard connector. The standard (in-stock) build connects -V to AC FG; a build with -V not connected to AC FG exists but must be applied for, so tell us if your end device needs a floating output.

All six models carry the same ten-standard approval list - there is no per-model exception on this datasheet, unlike the GST220A series where three of the approvals exclude the 36V model. The certification logo block on page 1 additionally shows IEC62368-1, and prints the Chinese standard as GB4943.1 rather than GB4943; the table above reproduces the page-2 wording. If your tender needs the exact certificate scope for a specific model, ask us and we will send the certificate copies.
All six models are certified to UL62368-1, CSA C22.2 No.62368-1, Dekra BS EN/EN62368-1, BSMI CNS15598-1, CCC GB4943, AS/NZS 62368.1, PSE J62368-1, BIS IS13252, KC 62368-1 and EAC TP TC 004. There is no per-model exception. Conducted and radiated emissions meet Class B limits to BS EN/EN55032 (CISPR32), FCC Part 15 / CISPR22, CAN ICES-3(B)/NMB-3(B), CNS15936, GB17625.1, EAC TP TC 020 and MSIP KN32.
The GST360A is rated for 3 seconds at roughly 1.25 times its continuous output - 415W on the 12V model, 425W on 15V, and 450W on the 24V, 36V, 48V and 55V models. It is a transient allowance for motor inrush, capacitive start-up and short bursts, not a continuous rating. Size your steady-state load against the rated power (330W / 340.5W / 360W), and keep the 3-second window in mind for anything that starts repeatedly.
No. The datasheet rates them individually: 12V is 330W (27.5A), 15V is 340.5W (22.7A), and 24V, 36V, 48V and 55V are 360W at 15A, 10A, 7.5A and 6.55A. Quoting "360W" on a 12V requirement overstates it by 30W, and on a 15V requirement by about 20W.
Because of current. The 12V model delivers 27.5A and the 15V model 22.7A, so MEAN WELL fits the 8-pin C8P (MOLEX 39-01-2080 equivalent) which spreads the load across four +Vo and four -Vo pins. From 24V up the current falls to 15A and below, and the 6-pin C6P (MOLEX 39-01-2060 equivalent) is used, with three +Vo and three -Vo pins. The model suffix tells you which one you are ordering: -C8P for 12V and 15V, -C6P for 24V to 55V.
Earth-referenced in the standard build. The datasheet states that the standard type (-V connected to AC FG) is the in-stock version, so the output sits on protective earth through the mains inlet - this is not an isolated floating output. A variant with -V not connected to AC FG is listed as an optional build that must be applied for (需申请). If your end device expects a floating output, or the load side already has its own earth reference, tell us before ordering so we can quote the correct variant.
No. The GST360A covers 12V, 15V, 24V, 36V, 48V and 55V only - there is no 20V model, even though the GST280A and GST220A both have one. If a 20V design is already tooled, the GST280A20-C6P (20V / 13A / 260W) is the closest desktop option at this power level, at lower rated power.
Because of the power band, not because of a weaker design. Efficiency Level VI sets a no-load ceiling of 0.21W for adapters between 49W and 250W output, and 0.5W above 250W - so a 360W platform is measured against the 0.5W limit. The GST360A publishes "below 0.5W" and meets Level VI. Comparing its no-load figure with a 120W adapter's 0.15W is comparing two different regulatory bands.
Overload trips at 135%~155% of rated output power, but the response depends on voltage: 12V, 15V, 24V and 36V enter hiccup mode and recover automatically once the fault is removed, while 48V and 55V shut the output down and need a restart. Over-voltage (105%~135% of rated output voltage) and over-temperature protection shut the output down and require a restart on every model. If your installation is unattended, plan for a remote power cycle or size the thermal design with margin so the OTP point is never reached.
GST360A is a Class I power supply. It connects through a 3-pole IEC320-C14 inlet and bonds the protective earth, so the mains side carries a protective earth conductor, and it uses a 94V-0 flame-retardant fully enclosed plastic housing. It is not a double-insulated Class II product and must be run from an earthed mains supply.
No. GST360A is an ITE product certified to the 62368-1 safety standard. For equipment with patient contact, use a 60601-1 certified adapter from the MEAN WELL GSM medical series instead, which provides 2xMOPP isolation. The adapter is in any case a component intended to be built into end equipment, so EMC and safety of the complete system must be confirmed with the finished device.
