The installation of access control systems has become widespread in our daily life. The access control systems can well protect our personal safety and property safety, and the access control systems are also very convenient in use. The most important thing in the access control system is the access control power supply.
1. The actual power of the power supply
It is good not only to achieve power, but also to achieve stable power and stable current output. By measuring the actual output voltage and current value of the power supply with a multimeter, check whether the output voltage and current can be at the rated output value, and determine the output voltage of the power supply. Is it stable.
2. Overload protection
Short circuit protection function, mainly to prevent the loss of voltage instability or wrong circuit connection,
3. Open circuit protection
When the power is supplied, other power supplies can be cut off by themselves to ensure the basic operation of the access control.
4. Charge and discharge management
Constant current charging ensures the power supply of other front-end equipment, prevents overcharge and overdischarge of the battery, and prolongs the service life of the battery; Test method: Use a multimeter to test the actual output current value and voltage value of the power supply to see if the output voltage and current can be at the rated output value.
5. Isolation function
The circuit has multiple outputs, and the failure of one circuit will not affect the normal operation of the access control. Test method: Here we can judge whether there are multiple outputs by the number of output ports of the power supply.
