AVT1478 B

The task of this simple system is to automatically disconnect any device from the power supply after a specified time. This is especially important if the source of energy is a battery or a battery and is useful especially in the construction workshop to protect prototypes and new constructions
The disconnecting machine does not take any current in the inactive state. Two buttons are provided for its servicing. The first one is used to turn on the machine and supply power to the protected circuits. After pressing it, the countdown of the time for automatic disconnection of the energy source begins. The second button is used to immediately disconnect the power supply.

The device is particularly recommended in electronic laboratories and on the website

Selected parameters:

• automatic disconnection of power after a specified time
• the possibility of a smooth change of the delay time
