The electric plug lock is suitable for office wooden doors and glass doors. Most of them are of the normally open type, and they fully comply with the fire control specifications of the tunnel doors. Electric plug locks and magnetic locks are the main lock bodies used in access control systems.
Electric plug lock purchase common sense:
The lock surface must have metallic luster, can't have obvious scratch, the standby current is about 300mA, the operating current is lower than 900mA. After a long period of electricity, the surface is slightly hot but not hot. The electric plug lock must have enough force to bounce off. When pressed down, the lock can automatically bounce up and forcefully. It is best to perform 4,000 on-off tests. If, in the process of discovery, the lock is weak, or it does not pop up, or it may If you do not, it is considered unqualified.
The difference between two-wire and multi-wire plugs?
The multi-wire electric plug lock is controlled by a single-chip microcomputer. The operating current of the electric lock is controlled by the single-chip microcomputer intelligently, the lock body is not too hot, and the delay control function and the door magnetic detection function are provided; the time delay control function can be adapted to the ground spring. Good door use, door magnetic monitoring function can provide the controller with real-time monitoring of door opening and closing status. Although these functions may not be available to you, the quality of the electric locks and the stability of the electric locks controlled by the SCM and the SCM are not on one level. Therefore, it is recommended that you do not need to save a little money. The two-wire power plug lock has a very simple internal structure and is just a current-driven solenoid coil mechanism. The operating current is large and the heat will be severe enough to damage the electrical lock.
DKJS-0B electronic mute lock uses a scientific, simple mechanical structure to achieve low current, low cost, low failure, and achieve a closed lock without noise. Easy installation, long life, good security and anti-theft performance. Suitable for building intercom and access control systems and various doors.
Electrical performance:
1, voltage: 10 ~ 18VDC
2, power-on time: 0.25 seconds 3, kai lock power: 20W
4, power line resistance: <1.5 ohm 5, adapt to the environment: -40 °C ~ 80 °C
Features:
1. The door is locked without noise and vibration.
2. Silent electronically-controlled kai locks can be opened or closed slowly. When a pull is applied to the door, it does not affect the electronically-controlled kai lock. The door opening method is first pushed and then pulled.
3, the wiring is simple, two-wire system, regardless of positive and negative.
4, the structure is simple and scientific, low current, low cost, low failure.
5, regardless of left open and right, easy to install.
6, to meet the various requirements of the installation of the door, the service life is more than 3 times the ordinary electric lock.
