Rated input voltage

Rated voltage: AC176~265V, operating voltage: AC220V±15%. Interface location: Three-position uncovered socket marked AC-L, AC-N, FG

Rated input current

Rated current: AC3.0A, current range AC1.0～4.0A

AC input frequency

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

Input surge current

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

Input voltage protection

The input allowable range is AC0~280V; the overvoltage protection point is AC300V±5V, and the power supply enters a non-restorable shutdown state.

Output overload protection

The +24V overload protection point is about 105%~120% of the rated output power; the overload protection is an online current limiting and voltage reduction method; the short circuit protection needs to reset the input

UPS battery management function

An external 24V lead-acid battery (capacity 5~30AH) is required for backup power supply. When the AC power supply is stopped, the system automatically switches to the backup power supply. The system switches without time interruption. When the AC power supply is normal, it automatically switches to the AC power supply and manages the battery.

It has the function of floating charging for external batteries (5~30AH), and each protection function can be automatically reset.

Power time parameters

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

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.
