JPS300P-D power supply with input-dependent loading
The G-Energy JPS300P-D supplies a nominal 5 V DC output for compatible LED cabinets. Its specification gives different power limits for low and high AC input and requires auxiliary heat sinking for natural cooling.
The PDF contains conflicting output-current entries. The table preserves the main and detailed values separately, so a higher current figure is not mistaken for a confirmed continuous rating.
Technical specifications
| Parameter | Specification |
|---|---|
| Model / document | G-Energy JPS300P-D; V1.0, 2016-10-11 |
| Rated output voltage / adjustment | 5.0 V DC / 4.95–5.15 V DC |
| Rated input / operating range | 100–240 V AC / 90–264 V AC |
| Output at 90–175 V AC | Main specification: 0–50 A; output-power table: 0–250 W |
| Output at 176–264 V AC | Main specification: 0–60 A; output-power table: 0–300 W |
| Conflicting current entries | Detailed output table instead lists 70 A at 90–175 V AC and 80 A at 176–264 V AC. These conflict with the main specification and require manufacturer confirmation. |
| Input frequency | 47–63 Hz |
| Maximum input current | 5 A at 90 V AC / 50 A load; 2.8 A at 176 V AC / 60 A load |
| Cold-start inrush | ≤200 A at 220 V AC |
| Power factor / efficiency | ≥0.95 at 220 V AC full load / ≥89% at 230 V AC and 50% rated load |
| Voltage accuracy / load regulation | ±1% / ±1% |
| Ripple and noise | ≤150 mVp-p at 220 V AC, full load, 20 MHz bandwidth with the specified output capacitors |
| Startup delay / rise time | ≤3 s / ≤50 ms at 220 V AC |
| Protection | Current limiting 85–130 A with self-recovery; overvoltage 5.5–6.5 V with hiccup protection; self-recovering short-circuit protection |
| Thermal protection | Case temperature 105°C ±8°C; recovery below 65°C ±8°C |
| Cooling | Natural cooling with close contact to a metal backplate; auxiliary aluminum plate at least 355 × 240 × 3 mm |
| Operating / ambient temperature | −30 to 60°C, typical 25°C; use the derating curves and provide adequate cooling |
| Storage conditions | Environment table: −40 to 85°C, 10–95% RH non-condensing; storage instructions separately specify −10 to 80°C and 10–90% RH |
| Dimensions | 235 × 60 × 35 mm; PDF appends ±0.5 tolerance |
| Mounting | Screw penetration into the supply body must not exceed 4.0 mm |

Frequently asked questions
Can the JPS300P-D supply 300 W at low AC input?
The output-power table specifies up to 250 W at 90–175 V AC and up to 300 W at 176–264 V AC. Input voltage and cooling conditions must be considered together.
Is the output rated at 50/60 A or 70/80 A?
The main specification lists 50 A at low input and 60 A at high input, while a detailed table lists 70 A and 80 A. This is a document conflict, not a confirmed higher rating. Obtain manufacturer confirmation for the supplied unit before designing around the higher values.
Does this power supply need a fan?
The specification describes natural cooling, but requires close contact with a metal backplate and an auxiliary aluminum plate of at least 355 × 240 × 3 mm. Natural cooling does not remove the heat-sinking requirement.
Can I adjust the DC output?
The documented adjustment range is 4.95–5.15 V DC around the nominal 5.0 V output. Confirm the connected LED module’s voltage requirement before adjustment.
What happens if the supply overheats?
Thermal protection is specified at a case temperature of 105°C ±8°C, with recovery below 65°C ±8°C. These are protection thresholds, not recommended ambient operating temperatures; follow the load/temperature curve and cooling instructions.
