Delayed Power-Saving Switch
 
The delayed power-saving switch is used by hotels to save electricity. When a guest checks in, inserting the room key card into the switch connects the main power supply, so that the lighting, TV and required sockets in the room become usable. When the guest leaves the room and removes the key card, the switch automatically cuts power after a 5-10 second delay, ensuring both convenience and energy saving.

There are currently two types of delayed power-saving switches: the general-purpose power-saving switch and the dedicated power-saving switch.

General-purpose power-saving switch: Uses the photoelectric principle to save power; any card can be used to connect the power. If a guest uses a business card or paper slip instead of the room key card and forgets to remove it when going out, it cannot effectively save power.
Dedicated power-saving switch: Built-in MCPU (microcomputer processor) and card reader; it saves power effectively by reading valid identification data from the card. Only the IC card or RF card of ADEL hotel door locks can be used to draw power; other cards, paper slips, etc. cannot. Only guests holding the hotel IC/RF card and hotel staff can make the switch work, truly and effectively saving electricity.

   Dedicated power-saving switch: built-in MCPU (microcomputer processor) and card reader; it saves power effectively by reading valid identification data from the card. Only the IC card or RF card of ADEL hotel door locks can be used to draw power; other cards, paper slips, etc. cannot. Only guests holding the hotel IC/RF card and hotel staff can make the switch work, truly and effectively saving electricity.

Financial Analysis of Savings from the Dedicated IC/RF Card Power-Saving Switch:
Economic benefits the dedicated energy-saving switch brings to the hotel: assume a hotel has ** rooms and each room effectively saves 1 kWh per day. Over 365 days a year, the total electricity cost saved is: 365 days ¡Á 1 kWh ¡Á £¤0.85/kWh ¡Á ** = £¤31,025. After using the dedicated energy-saving switch, the hotel saves at least over £¤30,000 in electricity costs each year.

Note: The ADEL dedicated IC card power-saving switch draws power only after reading valid identification data from the card. This differs from a type on the market today that draws power with any 4442 IC chip; such switches cannot be called dedicated power-saving switches and are essentially the same as general-purpose ones!

   The ADEL power-saving switch has a built-in transformer, using a transformer-based power supply. It adds lightning-strike, over-current and over-voltage protection designs, and differs greatly from traditional resistor-capacitor power supplies; it features high reliability and a long service life.
