Complete Qualifications
Changsong obtained ISO9001 quality system certification, ISO14001, OHSAS18001, CB certification; SEMKO and CE certification, etc.
There is a reliable mechanical interlocking device and electrical interlocking protection between the two circuit breakers, which completely eliminates the possibility of closing the two circuit breakers at the same time. The agency has obtained national patent products.
The intelligent controller adopts the single-chip microcomputer as the control core, the hardware is simple, the function is powerful, the expansion is convenient, and the reliability is high.
It has the function of short circuit and overload protection, automatic conversion function of overvoltage, undervoltage and phase loss and intelligent alarm function.
Automatic conversion parameters can be freely set externally.
It has the intelligent protection function of the operating motor.
The device is equipped with a fire control circuit, when the fire control center sends a control signal to the intelligent controller, both circuit breakers enter the open state.
Ambient air temperature of -5ºC to +40ºC,and at 24 hour average temperature does not exceed +35ºC.
The installation location no more than 2000 meters.
The maximum temperature of +40ºC,the air relative humidity is no more than 50%,at a low temperature can be allowed to have a higher relative humidity,such as 20ºC at 90%. special measures should be taken for occasional condensation due to temperature changes.
Pollution level:Grade 3
Installation category:3.
The two power lines are connected to the upper side of the switch,and the load line is connected to the lower side.
The location of installation should not have significant vibration,impact.
Supplementary Explanation
In special circumstances, manual mode can be used to switch between common or backup power sources
Can be used for single-phase ac220v power supply circuits, and the two power sources can be mains power generation machine solar power generation, street light electricity, batteries, etc., if it is dc or low voltage the power supply needs to be reversed by an inverter to ac 220v before being connected to a dual power supply
Switching is not a backup power source, that is, it cannot replace batteries
