Rated input current

Rated current: AC0.5A, current range AC0.5~1A

AC input frequency

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

Input surge current

The impulse current of the power supply grid at the moment of working power-on: the maximum value of cold start is 60A/10mS

Output overload protection

The +12V overload protection point is about 105%~120% of the rated output power; The overload protection is in the mode of online current limiting and voltage reduction; Short-circuit protection requires the input to be reset

UPS battery management function

External battery (capacity 5~30AH) is required for backup power supply, the system will automatically convert to backup power supply when AC power supply stops, the system conversion ≤ 50mS, and automatically switch to AC power supply and battery management when AC power supply is normal (BAT+ and BAT.SW need to be shorted to enable UPS function)

It has the function of floating charging the external battery (5~30AH), and the battery has an undervoltage of 10V±0.6V for load discharge, and the short-circuit protection function can be automatically reset.

Certified safety specifications

National standard GB-4943

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.
