Rated Input Voltage

Rated voltage: AC85～265V, operating voltage: AC78～290V. Interface position: Three-position 5.0-M3 interface. INPUT: AC-L, AC-N, FG

Rated Input Current

Rated current: AC90mA (AC220V) / AC180mA (AC110V), current range AC70mA～220mA

AC Input Frequency

Rated AC voltage frequency range 47～63Hz, sine wave

Inrush Current

The surge current to the power grid at the moment of power-on: the maximum value during cold start is 20A/10ms.

Input Overvoltage Protection

Input allowable range: AC0～280V; Overvoltage protection point: AC300V±5V, power supply enters irreversible shutdown state.

Output Overload Protection

The overload protection point is approximately 120% of the rated output power; the overload protection is a power-limiting pulse voltage-dropping method; the short-circuit protection is a pulse output power-limiting method.

Output Overvoltage Protection

------

Overheat protection

The protection point is set when the casing temperature is above +85℃±3℃; the automatic recovery setting is when the casing temperature is below +65℃±3℃; the overheat protection is a voltage drop mode.

Multi-unit series/parallel operation

Multiple units of the same power supply series can be used in series.

Power supply timing parameters

Setup time ≈ 200ms; Settlement time ≈ 50ms; Hold-up time ≈ 20ms

Isolation voltage parameters

[Input-Output: AC1.5KV, Input-Casing: AC1.5KV, Output-Casing: AC0.5KV] 50Hz, Power-on for 1 minute: Leakage current <5mA

Operating temperature parameters

The operating temperature drift coefficient is approximately ±0.05 [%/℃]; the absolute temperature rise coefficient is approximately 1.3 [℃/W]; when the operating output is at rated power, the absolute temperature rise of the machine body is 25℃±5℃.

Environmental conditions parameters

Storage environment: -20℃ to +85℃; 10% to 95%RH. Operating environment: -10℃ to +50℃; 20% to 90%RH. (Varies depending on the operating environment and power consumption)

Cooling method

Continuous operation mode, with natural cooling of the machine body (power consumption is affected by differences in the operating environment and installation location).

External dimensions and mounting dimensions

Specifications: L80×W50×H32mm3; Maximum size: L90×W50×H32mm3; Installation dimensions: bottom and side L75×W0mm2

Net weight and color

Total weight 160g; bottom shell is 1.5mm thick aluminum with a sandblasted black finish; top shell is 0.7mm thick iron with an electroplated black finish.

Design standards

National Standards GB-4943 and GB-9254

Note: 1) All the above test indicators were measured under the following conditions: within the rated input voltage and rated output load range, the environment was 25℃, 85%RH, and there was no wind.

2) Output DC voltage ripple test: A parallel stranded wire with a length of 30cm and a cross-section of 1mm², with 0.1μF and 0.47μF capacitors connected to one end, was bypassed at the test point. The maximum peak-to-peak value of the main frequency ripple Vp-p100Hz and the maximum peak-to-peak value of the combined ripple Vp-pmax were measured respectively.

3) Li voltage regulation rate: When the load is at the rated value, the input voltage varies within the rated range; Lo load regulation rate: When the input is at the rated voltage value, the load varies from zero to the rated value.
