Door: How many devices can the original power supply of Sintronic Company bring? If the power supply is insufficient, how should the wiring be connected to expand the power supply?
answer:
The original linear power supply (DC 12V 5A) of sintronic Company can normally load up to 4 electric mortise locks or 3 magnetic locks with a force of 280 kg, as well as the power supply of the corresponding card reader and controller. If in practical application There is insufficient power supply or the electric lock is overloaded. An external power supply can be used if the
There are electric locks or electric locks connected to the system. It is recommended to use an external power supply for power supply because the inrush current of the electric locks is as high as 3A. The original power supply cannot resist the impact and cannot guarantee the sufficient power of the system.
Suggestion: ◆Choose an external 8~15A DC 12V switching power supply, which can supply power to all locks of a controller at the same time.
Note: Since the linear power supply has no high-frequency ripple interference, it is suitable for the power supply of the main controller and card reader to avoid the possibility of high-frequency ripple interfering with the host's crash. Electric locks do not require high power quality, as long as the power is sufficient Yes. Therefore, the external power supply to the lock can use switching power supply, switching power supply, the current is large and effective
High power, low price, suitable for power supply to locks. In addition, it is necessary to pay attention to the wires connected to electric locks, which must be wires with a cross-sectional area greater than or equal to 1.0 square millimeters, and the longest can not exceed 100 meters)
Take the four-door one-way access control controller and the power-off-open electric lock (electric mortise lock magnetic lock) as examples to illustrate the connection method of the external power supply (if the power-off-close electric lock such as the electric lock with an electric lock is used, then In the figure below, all the terminals connected to NC should be changed to NO. As shown below.
