A wall stabilizer, also known as a voltage stabilizer or voltage regulator, is an electrical device used to regulate and stabilize the voltage supplied to electrical and electronic equipment. It is designed to protect devices from voltage fluctuations, which can occur due to irregularities in the power grid, and maintain a stable voltage within an acceptable range.

Here are some common features and functionalities you might find in a wall stabilizer like the SONIK WALL STABILISER SWS-5000:

1. Voltage Range: The stabilizer will have a specified input voltage range within which it can operate effectively. For example, it might be designed to handle input voltages between 100V to 280V or similar ranges.
2. Power Capacity: The power capacity of the stabilizer will indicate the maximum load it can handle, usually measured in volt-amperes (VA) or kilovolt-amperes (kVA).
3. Automatic Voltage Regulation (AVR): The stabilizer will feature AVR technology, which automatically adjusts the output voltage to maintain a stable voltage level despite fluctuations in the input voltage.
4. LED Indicators: Stabilizers often come with LED indicators to show the status of the input voltage, output voltage, and other operational information.
5. Delayed Start: Some stabilizers may have a delayed start feature to protect connected devices from sudden voltage surges during power restoration after an outage.
6. Overload Protection: The stabilizer will likely have overload protection to safeguard against excessive power demands and prevent damage to the stabilizer and connected equipment.
7. Short Circuit Protection: A built-in short circuit protection feature can help prevent damage in case of a short circuit in the connected devices.
8. Wall-Mountable Design: Wall stabilizers are designed to be mounted on walls, saving floor space and providing convenient installation.
