GEQ series dual power supply switching cabinet can realize power supply switching between two units and between units and utility power and load. The two power supplies are monitored and controlled in real time through Comet IA-NT controller or multi-functional energy meter.
Through the optional IA-NT controller, the switching time of main and backup power can be set, and the switching between the two power sources can be realized manually or automatically.
GEQ series dual power supply switching cabinet adopts GGD cabinet type or wall-mounted self-made cabinet, Comet IA-NT controller and ATS switch body configuration, which has the characteristics of stable working performance and low failure and maintenance rate.
GEQ series double power switching cabinet is mainly used for important loads in low-voltage power supply system, such as fire-fighting, hospitals, banks and data centers, where the load needs to be switched from main power supply to standby emergency power supply to ensure continuous and reliable operation of important loads.
Standardized copper row and alignment standards;
Optional airline connector, convenient to use with the user's site arbitrary configuration to improve reliability.
Optional ATS controller with automatic/manual mode selection;
Spare terminal signal lead-out, easy for customers to temporarily increase the function;
The optional IA-NT-PWR controller can realize the function of short-time parallel connection of two power sources;
ATS body with MCCB or ACB circuit breaker combination, with circuit breaker short-circuit protection function;
With the ATS controller, the three-phase utility monitoring function is available;
The switch body can choose to use PC grade or CB grade, the reliability and safety of PC grade products are higher than CB grade products.
The ATS cabinet is equipped with electrical and mechanical interlock functions to ensure the accuracy and safety of switching.
The main functions of controller ATS2
"
When the mains power fails, the controller sends a start signal for the generator set after a delay of 0 to 6000 seconds (adjustable). After the generator set operates stably, the load automatically switches to the power generation end after a delay of 0 to 600 seconds (adjustable).
When the mains power is restored, the controller automatically controls the ATS transfer switch. After a delay of 0-3600 seconds (adjustable), the load is switched to the mains power end. After another delay of 0-6000 seconds (adjustable), a signal to stop the operation of the generator set is sent. The generator set automatically shuts down after a cooling delay.
The ATS control cabinet has the function of manual and automatic power switching.
The ATS has the function of priority of mains power and is controlled by the ATS250 controller.
The ATS detects two three-phase voltage fault signals (including undervoltage, overvoltage, undervoltage, phase loss, etc.). When the municipal power supply fails, it can promptly send a control signal to the self-starting end of the generator set, allowing the unit to start automatically and prepare for power supply.
