 ■ structural features 
 Double power automatic switch is composed of two parts of the device body and the intelligent automatic controller. 
 □ device body by two with motor operating mechanism of circuit breaker (model specifications, see the terms of the technical parameters) and accessories (auxiliary alarm contacts, etc.), composed of the institution of mechanical interlock, electrical interlock, fuses, terminals, and all zero The components installed on a metal plate. 
 □ automatic controller by the new microcontroller and output modules. 
 Through a dedicated aviation plug interface and special length not exceeding 2 m shielded cable connection between the two, composed of intelligent control systems, intelligent system control power supply voltage is 220V, 50/60Hz. 
 ■ PERFORMANCE 
 □ controller at the same time the two voltage detection, power supply voltage higher than the rating of 110% (adjustable) ruled over-voltage, lower than the rating of 85% (adjustable) judgments owed to the voltage (or loss) The microcomputer control circuit logic to determine the above test results, the results of sub-gate delay (adjustable) circuit to drive the corresponding instruction issued to the motor operating mechanism or closing instructions, the above test results in the intelligent automatic control panel LCD display displayed can also connected through the serial port and the computer software control for the user to find out the reasons, in order to repair the fault line in the shortest possible time, dual power supply to restore the original state. 
 □ intelligent automatic controller to control functions are divided into three 
 △ automatic recovery (R) apply to the grid and the grid. 
 Automatic controller to automatically switch the two power supply (ie, common power supply and standby power), the normal state by the common power supply. Common power failure or abnormal (any one phase voltage, overvoltage, undervoltage, loss of pressure or phase), automatic switch to standby power supply, when the commonly used power is restored, automatically returns to the common power supply. When the standby power failure or abnormal (any one phase voltage overvoltage, undervoltage, loss of pressure or phase), the controller issued a common or standby power alarm. 
 △ a vote of no self-complex (S) on the grid with the grid. 
 Since the vote not automatically switch to the automatic controller from complex two-way power (ie, common power supply and standby power). In either a power abnormal (either a phase voltage of the overvoltage, undervoltage or phase), the delay is set automatically switch to another normal power, but when abnormal power is restored, you can not auto-reply. 
 △ power grid and power generation (F) [for the power grid and power generation systems, the conversion time should be set to 15 seconds] 
 Two-way power grid and power generation, the automatic controller of the grid - power automatic switch, delay instructions issued by the power generation in the grid voltage is less than 85% of rated voltage, power generation instruction (a set of normally open to normally closed contact output). Disconnect the load circuit when the power voltage reaches 85% of rated voltage, the start grid, uninstall instructions to unload the secondary load to another set of normally open normally closed contact output, and then convert connected on-delay power sources. When the grid is back to normal (more than 85% of rated voltage), the intelligent controller logic to determine automatically the load circuit is disconnected from the power sources, switch to the power grid. 
 □ dual power supply dual state 
 System load pairs of sub-state, regardless of the power of the two groups is normal and the system "manual" and "automatic" preset state, the system remains in the double sub-state. Only in the operating keyboard (manual) (automatic), the system is transferred to non-dual sub-state (manual - commonly - standby or automatic - complex - complex) loads have a power supply according to the above treatments. 
 □ protection functions: overload and short circuit protection, phase loss, circuit protection, and voltage, under voltage protection 
 1 seconds -30 seconds for automatic switching time adjustable (If you need more time please contact with the factory), high-performance single-chip process control, anti-interference ability, high precision protection; small size, high stability, continuous and reliable work and so on. 
 □ with the central computer control communication interface, remote control fire signal output. Noise-free operation, energy saving, in line with the national green electrical product standards.
