First, dual power introduction:
The dual-power explosion-proof switch box is a device controlled by a microprocessor and used in a grid system to switch between the power of the network and the power of the network or the power of the generator and the power of the generator, so that the power of the power source can be continuously supplied. Series dual power supply, when the common power suddenly fails or fails, it is automatically put into the standby power supply through the dual power supply switch, (the standby power can also be powered by the generator under small load), so that the equipment can still operate normally. The most common are elevators, fire protection, surveillance, lighting, etc.

Third, the use of places:
The dual-power explosion-proof switch box is suitable for dual power supply such as fire control and other key loads in the fields of chemical engineering, medicine, gas, petroleum, etc. EPS is suitable for EPS to solve emergency lighting, accident lighting, fire-fighting facilities and other first-level load power supply equipment. As the main objective, provide an emergency power supply system with independent circuits that meets fire protection regulations. UPS is mainly to provide electricity for IT industry equipment, providing pure, uninterrupted backup power. The diesel generator power supply mode is suitable for use in conjunction with ATS, EPS, and UPS in power supply sites that require a long backup power supply.
