Rated input current

Rated current: AC220V: AC2.5A, current range AC2.2A～3.5A;

AC input frequency

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

Input surge current

The impact surge current on the power supply grid at the moment of power-on: the maximum value during cold start is 55A/10mS.

Input overvoltage protection

The overload protection point is about 108% of the rated output current, and the protection is a current limiting and voltage reduction method; the short circuit protection is an online voltage shutdown method, and the input needs to be reset to recover.

Output undervoltage protection

The undervoltage protection point is about 10% of the rated output voltage. The protection is an online voltage shutdown mode. The input needs to be reset to recover.

Working overheat protection

Overheating protection is when the shell temperature is higher than about 85±3℃, and the protection is in the online voltage shutdown mode; automatic recovery is when the shell temperature is lower than about 65±3℃

Multi-machine serial and parallel function

The same series of power supplies are allowed to be used in series with multiple machines, but current sharing is not allowed.

Power time parameters

Preparation time (SETUP TIME) ≈ 200mS; Stability time (RISE TIME) ≈ 50mS; Holding time (HOLD UP TIME) ≈ 20mS

Isolation voltage parameters

[Input-output: AC1.5KV, input-casing: AC1.5KV, output-casing: AC0.5KV] 50Hz power on for 1min: leakage current <5mA

Operating temperature parameters

The working temperature drift coefficient is about ±0.05[%/℃]; the absolute temperature rise coefficient is about 0.13±10%[℃/W]; when the working output is rated power, the absolute temperature rise of the body is 35℃±5℃

Environmental condition parameters

Storage environment: -20℃～+85℃; 10%～95%RH. Working environment: -10℃～+40℃; 20%～90%RH. (Varies depending on usage environment and power)

Working heat dissipation method

Designed for continuous working mode, air cooling and heat dissipation (differences in usage environment and installation location affect power usage)

Appearance installation dimensions

Maximum size: L280×W120×H50mm3;

Net weight and appearance

The total weight is about 1700g; the bottom shell is made of 2.0mm thick aluminum, and the polished surface is silver and bright; the cover is 0.8mm thick iron, and the nickel-plated surface is silver and bright

Note: 1) The above detection indicators are measured under the following conditions: within the input rated voltage and output rated load range, the environment is 25℃, 85%RH. , when there is no wind around

2) Output DC voltage ripple detection: Use a parallel twisted wire with a length of 30cm and a cross-section of 1mm2 connected to one end of a 0.1μF and 0.47μF capacitor to bypass the detection point and detect 100Hz respectively.

The maximum peak-to-peak value of the main frequency ripple is Vp-p100Hz and the maximum peak-to-peak value of the comprehensive ripple is Vp-pmax.

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