Model and Selection

Complete model GST360A12-C8P.
Series GST360A industrial desktop adapter.
Input construction Class I; 3-pole IEC320-C14, with FG.
DC termination Pins 1–4 +Vo; pins 5–8 −Vo. MOLEX 39-01-2080 equivalent.
Power conversion Universal input with built-in active PFC.
Enclosure and indication Fully enclosed 94V-0 flame-retardant plastic case; LED power-on indicator.
No-load consumption <0.5 W.
Energy efficiency Level VI.

Select the complete model, output voltage, current capacity, connector and polarity for the load. A matching connector shape alone does not establish electrical compatibility.

Output Ratings

Nominal output 12 VDC.
Rated current 27.5 A.
Output current range 0–27.5 A.
Rated output power, maximum 330 W.
Ripple and noise, maximum 120 mVp-p.
Voltage tolerance ±5.0%.
Line regulation ±1.0%.
Load regulation ±5.0%.
Efficiency, typical 91% for this C8P version.
Peak power 415 W for 3 seconds. This is a short-duration peak, not a continuous-output rating.

Observe the stated current and power limits together. Unless otherwise specified, measurements use 230 VAC, rated load, 25°C and 70% RH. Voltage tolerance includes set-up tolerance, line regulation and load regulation. Line regulation is measured from low to high input at rated load.

Ripple and noise are measured at 20 MHz bandwidth using a 12-inch twisted pair terminated with parallel 0.1 µF and 47 µF capacitors.

The output-voltage set point is measured at the DC plug terminals with 50% load.

Input and Timing

AC input 85–264 VAC; 47–63 Hz.
DC input 120–370 VDC.
Power factor, typical PF >0.95 at 230 VAC and PF >0.98 at 115 VAC, at full load.
AC current, typical 3.8 A at 115 VAC; 2 A at 230 VAC.
Cold-start inrush, maximum 95 A at 115 VAC; 120 A at 230 VAC.
Set-up / rise time 2000 ms / 50 ms at 230 VAC; 2000 ms / 50 ms at 115 VAC, at full load.
Hold-up time, typical 8 ms at both 230 VAC and 115 VAC, at full load.
Leakage current, maximum 1.5 mA at 240 VAC.

Set-up time is measured at the first cold start. Repeated power switching may increase the set-up time. Apply the low-input derating curve.

Protection

Short circuit / overload 135–155% of rated output power. Hiccup mode; automatic recovery after fault removal.
Overvoltage 105–135% of rated output voltage. Output shutdown; reapply input power to recover.
Overtemperature Output shutdown; reapply input power to recover.

Cooling and Environment

Working ambient −30 to +70°C, subject to the model-specific derating curves.
Temperature derating Horizontal installation: full load from −30 to 40°C, then 80% at 50°C, 65% at 60°C and 50% at 70°C.
Input-voltage derating At 60 Hz, 70% load at 85 VAC, rising to 85% at 100 VAC; the graph holds 85% up to the 120 VAC transition, with 100% from 120 to 264 VAC.
Working humidity 20–90% RH, non-condensing.
Storage −40 to +85°C; 10–95% RH, non-condensing.
Temperature coefficient ±0.03%/°C over 0–40°C.
Vibration 10–500 Hz, 2 G; 10 minutes per cycle, 60 minutes along each X, Y and Z axis.
Altitude derating Above 2000 m, reduce permissible ambient temperature by 3.5°C per 1000 m for fanless operation.
Operating altitude Up to 5000 m, with altitude and temperature derating.
Overvoltage category OVC II under UL62368-1 and BS EN/EN62368-1, up to 5000 m.

Keep the adapter unobstructed and apply both input and temperature limits. The plotted operating-temperature range is not a full-power guarantee at every input voltage.

Dimensions and Connections

Enclosure dimensions, L × W × H 220 × 95 × 46 mm; drawing tolerance ±1 mm.
Attached DC cable UL2464 16AWG × 6C; 1000 ±50 mm.
Default DC plug C8P: Pins 1–4 +Vo; pins 5–8 −Vo. MOLEX 39-01-2080 equivalent.
Grounding Class I, with protective earth through the 3-pole AC inlet; standard DC −V is connected to AC FG. A DC −V-to-FG isolated option is available by request; it is not the standard configuration.
AC cord The catalogue specifies the AC inlet but does not state that a detachable mains cord is included. Select a suitable region-approved cord for this inlet and load.

Use the numbered connector drawing for orientation; do not infer pin numbers from a photograph. Match the mating connector, contacts and wire rating to the actual current. The alternative plug references below identify options, not extra items included with this adapter.

DC Connection Selection

The default C8P termination is specified for this voltage. The catalogue restricts MIC4 and C4P alternatives to 36–55 V models; select the original C8P arrangement for this 12 V model. Other terminations require a separately confirmed configuration.

Harmonic current / flicker BS EN/EN61000-3-2 Class A and GB9254; BS EN/EN61000-3-3.
ESD immunity BS EN/EN61000-4-2: 15 kV air and 8 kV contact, Level 4.
RF field / EFT immunity BS EN/EN61000-4-3: 3 V/m, Level 2; -4-4: 1 kV, Level 2.
Surge immunity BS EN/EN61000-4-5: 1 kV line-to-line and 2 kV line-to-FG, Level 3.

Voltage dips and interruptions BS EN/EN61000-4-11: >95% dip for 0.5 periods, 30% dip for 25 periods, and >95% interruption for 250 periods.

The adapter is considered an independent unit, but the complete equipment must still be checked for compliance with applicable EMC directives in its actual installation. Use approvals applicable to the exact model and market.

Weight and Reliability

Catalogue weight reference 1400 g: catalogue packing reference per unit; not a measured net or shipping weight.
