Durdable Automatic Changeover Switches

We make, export and supply of Durdable Automatic Changeover Switches in Malerkotla, Punjab, India. The system is a very cost-effective solution, and can significantly reduce fuel consumption and maintenance costs. This system is designed to reduce fuel consumption and maintenance costs, and increase user convenience, as it governs when a generator will run. So, there is no need to manually start and stop the generator each time electricity is required.

Load Start senses when a load is applied and automatically starts the generator. When the load is removed, the system senses the change and automatically turns off the generator. The flexibility of Load Start means that virtually all loads or mixtures of loads will work with the system.

Security Lighting Feature

Load Start also provides a security function in that it allows sensor-controlled security lighting to be connected, so that if a sensor detects an intruder, the generator is switched on and activates the security lighting. As an added bonus, the system can be augmented to include its own PIR light sensor meaning that any connected security lights only come on during the night.
