175 x 72 x 35mm | 85~264VAC / 120~370VDC Input | 6 Output Models 12V ~ 48VDC | 138W~160W | 3-Pole IEC320-C14 AC Inlet | Class I with Protective Earth | Active PFC, PF>0.98 | No-Load <0.15W | Efficiency Level VI, up to 94% | Leakage 0.75mA Max | -30~+70C | 3-Year Warranty
The MEAN WELL GST160A series is a high-reliability 160W AC-DC desktop single-output green adapter built into a fully enclosed 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 48VDC - adding a 36V model to the usual 12V / 15V / 20V / 24V / 48V line-up - serving consumer electronic devices, telecom equipment, office equipment and industrial equipment.
The input stage uses active power factor correction: power factor is above 0.93 at 230VAC on the 12V and 15V models, above 0.94 from 20V upwards, and above 0.98 at 115VAC at full load. Maximum leakage current is only 0.75mA at 240VAC despite the higher output power. Withstand voltage is 3KVAC input-to-output, 2KVAC input-to-FG with the output-to-FG path effectively shorted, and insulation resistance is 100M Ohms minimum at 500VDC. The 94V-0 flame-retardant enclosure is fully sealed, so no live part is exposed in normal operation. This is an ITE product: for patient-contact medical equipment choose a 60601-1 certified adapter from the GSM series instead.
Typical efficiency runs from 90% on the 12V model to 94% on the 48V model, with no-load power consumption below 0.15W across the whole series, meeting Efficiency Level VI and complying with USA EISA 2007/DoE, Canada NRCan, Korea K-MEPS, AU/NZ MEPS, EU ErP and CoC Version 5. Efficiency is published per model and is not strictly proportional to output voltage: the 36V model is rated 92%, slightly below the 24V model's 93%, and that is the datasheet figure rather than a rounding artefact. Safety approvals cover UL62368-1, CSA C22.2 No.62368-1, TUV BS EN/EN62368-1, IEC62368-1, BSMI CNS15598-1, CCC GB4943.1, PSE J62368-1, AS/NZS 62368.1, BIS IS13252, KC K60950-1 and EAC TP TC 004, with conducted and radiated emissions held to Class B limits.
The standard output plug on all six models is the R7B 4-pin power DIN with lock, and on the R7B the negative output is connected to AC FG, so the output is referenced to protective earth rather than floating. Tuning fork, DIN, XLR, MOLEX and AMP connectors can be fitted at the factory, and a quick-change plug adapter is offered for the P1J and P1M tuning-fork plugs - rated 24~48V / 7.5A maximum, which rules out the 12V (11.5A), 15V (9.6A) and 20V (8A) models. Protections cover short circuit, overload (105%~150% of rated power, hiccup mode with auto-recovery), over voltage (105%~135% of rated output voltage, hiccup mode at 10% load) and over temperature (shutdown, restart after cooling). The 175 x 72 x 35mm adapter weighs 660g, operates from -30C to +70C and is backed by a 3-year warranty.
Output ratings for all six GST160A 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) | Efficiency (Typ.) |
|---|---|---|---|---|---|
| GST160A12-R7B | 12V | 11.5A | 0 ~ 11.5A | 138W | 90% |
| GST160A15-R7B | 15V | 9.6A | 0 ~ 9.6A | 144W | 91% |
| GST160A20-R7B | 20V | 8A | 0 ~ 8A | 160W | 93% |
| GST160A24-R7B | 24V | 6.67A | 0 ~ 6.67A | 160W | 93% |
| GST160A36-R7B | 36V | 4.44A | 0 ~ 4.44A | 160W | 92% |
| GST160A48-R7B | 48V | 3.34A | 0 ~ 3.34A | 160W | 94% |
Efficiency is published as one figure per model, because the standard R7B plug is the only build listed for this series. It does not rise monotonically with voltage: 36V is specified at 92%, below the 24V model's 93%. Models are 12V 138W, 15V 144W and 160W for 20V / 24V / 36V / 48V - current is capped by the 160W platform, so the lower voltages do not reach the full 160W.

Overload and over-voltage protection are specified once for the whole series rather than per model: overload trips at 105%~150% of rated output power in hiccup mode with automatic recovery, and over-voltage trips at 105%~135% of rated output voltage in hiccup mode at 10% load. Both are listed in full in the Input & Protection table below.

Note: quick-change adapter availability is listed per plug family as published in the MEAN WELL datasheet. On the GST160A only the P1J and P1M tuning-fork plugs accept a quick-change adapter, and only from 24V to 48V at 7.5A maximum - the 12V model delivers 11.5A, the 15V model 9.6A and the 20V model 8A, all above that limit, so those three run on their factory-fitted plug only. Every other style is factory-fit and requires a minimum order quantity. On the standard R7B plug the negative output is connected to AC FG; the optional C6P and C4P connectors leave FG unconnected to the output connector, so confirm your grounding scheme when ordering. Wire colours on stripped-lead versions are for reference only.

GST160A is certified to UL62368-1, CSA C22.2 No.62368-1, TUV BS EN/EN62368-1, IEC62368-1, BSMI CNS15598-1, CCC GB4943.1, PSE J62368-1, AS/NZS 62368.1, BIS IS13252, KC K60950-1 and EAC TP TC 004. 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. ESD immunity is Level 4 at 15KV air and Level 4 at 8KV contact, and EFT immunity is Level 3 at 2KV.
Earth-referenced, on the standard build. The datasheet R7B pin definition states that the negative output (-V) is connected to AC FG, so the output sits on protective earth through the mains inlet - this is not an isolated floating output. If your end device expects a floating output, or if the load side already has its own earth reference, tell us before ordering: the optional C6P and C4P connectors are specified with FG not connected to the output connector, and a modified build can be discussed with a minimum order quantity.
No. The 12V model is rated 138W (11.5A) and the 15V model 144W (9.6A). The 20V, 24V, 36V and 48V models deliver the full 160W. All six share the same 175 x 72 x 35mm housing and the same 85~264VAC / 120~370VDC input range. The series starts at 12V: there is no 5V, 7.5V, 9V, 18V or 28V model, so if you need a voltage below 12V choose GST40A or GST60A instead.
Because that is the published figure. The GST160A datasheet specifies 93% for both the 20V and 24V models, 92% for the 36V model and 94% for the 48V model. Efficiency on this platform is not a straight line with output voltage, and 36V is the model where the switching and transformer design sits least favourably. Quote 92% for GST160A36-R7B - do not carry the 24V or 48V number across, and do not use the series headline of 94% when the end customer is comparing a 36V design.
The standard plug on all six models is R7B, a 4-pin power DIN with lock and centre positive. Tuning fork (P1J, P1M), DIN 4-pin female (R7BF), DIN 5-pin (R1B), XLR (MIC4), MOLEX 39-01-2060 (C6P) and AMP 1-480702-0 (C4P) can be fitted at the factory subject to a minimum order quantity. For small quantities a quick-change DC plug adapter is available for the P1J and P1M tuning-fork plugs, rated 24~48V at 7.5A maximum.
No. The quick-change adapter is rated 7.5A maximum and 24~48V, while the 12V model delivers 11.5A, the 15V model 9.6A and the 20V model 8A. Only the 24V (6.67A), 36V (4.44A) and 48V (3.34A) models are within the limit. On the three lower-voltage models the plug is factory-fitted and cannot be swapped in the field.
GST160A is a Class I power supply. It connects through a 3-pole IEC320-C14 inlet and bonds the protective earth, which is why 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.
Overload protection trips at 105%~150% of rated output power and runs in hiccup mode, recovering automatically once the fault is removed. Over-voltage protection trips at 105%~135% of rated output voltage and is also specified as hiccup mode at 10% load. Over-temperature protection shuts the output down and requires a restart after the unit has cooled. Short circuit protection recovers automatically.
GST160A is the next platform up: 160W instead of 120W, six voltage models instead of five because a 36V version is added, and a larger housing at 175 x 72 x 35mm / 660g against 167 x 67 x 35mm / 575g, so it is not a drop-in mechanical swap. Input current rises to 1.85A at 115VAC, inrush to 95A / 120A, EFT immunity to Level 3 at 2KV, and the over-voltage protection now recovers in hiccup mode rather than latching off. Gain on the other side is a 94% peak efficiency model and I/P-FG withstand voltage of 2KVAC.
No. GST160A 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 and touch current below 50uA. 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.
