The MEAN WELL UHP-200A-5 is a 5 V, 40 A enclosed power supply for LED displays, rated at 200 W. Its 26 mm profile, active PFC and DC OK signal suit compact sign cabinets. Full performance requires the specified mounting plate, clearances and input/temperature derating.

47-63 Hz |
| Temporary surge-input withstand |

88.5% |
| Typical power factor |
≥0.97 at 115 VAC; ≥0.95 at 230 VAC, full load |
| Typical AC input current |
2.4 A at 115 VAC; 1.2 A at 230 VAC |
| Typical cold-start inrush current |
85 A at 230 VAC |
| Leakage current |
<1.0 mA at 240 VAC |
| Set-up / rise time |
2000 / 200 ms at 230 VAC and full load; 3000 / 200 ms at 115 VAC and 80% load |
| Typical hold-up time |
10 ms at 230 VAC; 10 ms at 115 VAC |
Unless otherwise stated, specifications are measured at 230 VAC input, rated load and 25°C ambient. 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.
Set-up time is measured at the first cold start; repeated on/off switching can increase it. Transient-response measurements require at least 10% load. The catalogue tolerance note includes line and load regulation.
Protection and DC OK Signal

| Overvoltage recovery |
Hiccup mode; automatic recovery after the fault is removed |
| Overtemperature protection |
Output shutdown; automatic recovery after the fault condition is removed |
| DC OK state |
Contact closed when the supply turns on; contact open when it turns off |
| DC OK maximum rating |
10 VDC / 1 mA |
| CN1 signal pins |
1: DC OK +V; 2: DC COM |
Wire the DC OK interface according to the optocoupler circuit and polarity shown in the datasheet. It is a low-current status interface, not an additional power output.
Terminals and Matching Connector Parts

1: AC/L; 2: AC/N; 3: FG / protective earth |
| TB1 terminal reference |
DECA T14-EM11033703; maximum tightening torque 13 kgf·cm |

The JST housing and crimp-terminal codes identify the matching parts for a DC OK lead. Select them when assembling the signal cable; the catalogue does not state that a completed lead or the mating parts are supplied with the power supply. The TB references identify the terminals in the mechanical drawing.

The datasheet requires the mounting plate to achieve the published thermal and input-voltage curves. Keep its surface even and smooth, or use thermal grease as described. Apply input-voltage and temperature limits together; the full temperature range is not a full-load rating.

This is a component power supply; verify EMC and safety in the completed equipment. The catalogue EMC test used a 360 × 360 × 1 mm metal plate. That test plate is separate from the 380 × 380 × 3 mm thermal-installation recommendation.
CISPR 32 Class A equipment may cause radio interference in a residential environment.
