3 phase changeover switch is suitable for dual power supply of key loads such as fire fighting in construction field. EPS is suitable for EPS, which aims at solving first-class load power supply equipment such as emergency lighting, accident lighting, fire fighting facilities and so on. It provides an emergency power supply system with independent circuit in accordance with fire protection regulations. UPS mainly provides electricity for IT industry equipment, providing pure and uninterrupted backup power supply. Diesel generator power supply mode is suitable for use in electric field which needs long backup power supply, in conjunction with ATS, EPS and UPS.
Upon sensing the loss of normal or street power, the ATS logic signals the emergency engine or turbine generator system to start. When the emergency source of power is available at the ATS, the control logic samples the source to ensure critical parameters are within proper tolerance. At this point, the ATS will transfer to the emergency power supply.
These steps are reversed upon the return of the normal power source. The ATS logic will again verify the street power is within the desired parameters and stable prior to retransfer. Once the ATS is back in the normal position, the ATS logic dictates a cool down period for the emergency power system. Note that most set points and timing functions are adjusted to the customer’s requirements.
