Schematic diagram of plug-in card power connection for hotels?

The power connection diagram of the hotel card is as follows:

Generally, the power take-off switch is powered by high voltage 220V, equipped with high power 30A relay, and the load is 6600W, which can meet the power load of hotel rooms. There is a luminous LED blue light indicator on the power switch, which conforms to the trend of modern hotels and is convenient for guests to operate at night.

According to the different types of cards used in hotel door locks, power access switches are divided into: magnetic card power access switch, ic card power access switch, T5557 card power access switch, M 1 card power access switch, room number and time identification power access switch, and networking power access switch.

The hotel room power switch is suitable for all kinds of star hotels, motels, budget hotels, apartments, office buildings and so on. It can effectively save electricity for the hotel and control all fixed room lighting and switch sockets. Other cards or pieces of paper can't get electricity, which effectively saves the energy in the guest room.

Extended data:

Power-on principle of card: Generally, the power-on switch of card consists of three parts: high and low voltage power conversion part, identification card part and output part. Among them, there are many ways to convert power supply, such as switching power supply, resistance-capacitance step-down, transformer and so on.

The high-low voltage conversion part reduces alternating current to direct current through rectification, and provides it to the identification part and the output part through low-voltage power supply.

The part of identifying the card is to detect whether the inserted card meets the preset standard.
