Product Detail

One. power supply overview 

1. Input characteristics :

(1) Input voltage 

Input voltage range : 90--264Vac

Nominal voltage range: <Rated input voltage range>: 100--240Vac

(2) Input frequency :

Nominal frequency <rated frequency>: 50 / 60Hz.

Change frequency <adjustment frequency>: 47 / 63Hz

(3) Maximum input current :

1Arms max at any input voltage and rated value. DC output rated load

When the input AC voltage is the lower limit voltage of the rated value and the load is fully loaded, the maximum input AC current is 1A.

(4) Surge current :

Maximum 40 ampere cold start with 230Vac input under rated load and 25℃ environment.

When the output is rated load, the ambient temperature is 25°C, and the maximum surge current is less than 40A when inputting 230Vac cold state.

(5) AC leakage current :

Maximum 0.25 mA under 230Vac input.

When the input voltage is 230Vac, the maximum leakage current is 0.25mA.

(1) Output power <AC input 115V / 230V, output power>;

Minimum voltage, maximum load, peak load

9V 0A 3A 4A

Note: The continuous working time cannot exceed 3 minutes when outputting the average power.

(2) Combined load/line regulation rate <load characteristic/regulation rate>:

Voltage line regulation rate load regulation rate

9V±3%±5%

(3) Ripple and noise :

Voltage ripple and noise (maximum)

9V <200MV

When measuring with Max, the ripple and noise are as follows. The bandwidth is 20MHz, and the behavior is 47uF/0.1uF, cross-connected at the test point.

Test conditions: Under normal operation of any load, use a spectrum bandwidth of 20MHz to connect to the output terminal of the charger, and at the same time the output terminal is connected in parallel with a 47uF electrolytic capacitor and a 0.1uF ceramic capacitor.

(4)  rise time:

Output voltage 115V/230Vac & full load

9V 150 ms

(5) Hold time :

Output voltage 115V/230Vac & full load

9V 5 ms

 (6) Efficiency :

The lowest 78% of input and output maximum load at 115V/230Vac.

When inputting 115V/230Vac and outputting maximum load, minimum 78%

 (7) Overshoot:

Up to 10% when the power is turned on or off.

When the power is turned on or off, the maximum is 10%.

(8) Short-circuit protection 

Under normal load, the short circuit output (9V) circuit will not damage the power supply. After eliminating the short circuit, the power supply should be able to work normally

When the output is short-circuited under normal load, the power supply is damaged; when the short-circuit is removed, the power supply resumes work.
