Very Early Air Sampling System (also known as Aspirating Smoke Detection System) is an advanced fire warning device that continuously takes air samples through a network of ducts installed in a protected area and detects smoke particles in the air by means of built-in highly sensitive sensors. The power box of such a system is one of its important components and is responsible for providing a stable power supply to the entire system.
The power supply box usually has the following features and functions:
1. **Stabilized power supply**: to ensure that the system can operate continuously and stably.
2. **Battery Backup**: Equipped with a battery backup to ensure that the system can continue to work for a period of time in the event of a power outage.
3. **Voltage Conversion**: Converts the input AC power into DC power suitable for the work of each part of the system.
4. **Overload protection**: automatically cuts off the power supply to protect the equipment when the current…
