Performance characteristics
Controller at the same time on the voltage of each phase of the two-way power line detection, and comparison to determine when the supply voltage is less than 35% -40% of the rated voltage, the controller, the test results directly to the controller, and through the delay circuit delay after the conversion instructions issued to the electrical operating mechanism.
Grid - the grid since the cast from the complex transfer switch (LCD type, the conversion time is adjustable)
Change-over switch and automatic recovery control functions are shown in Table automatic control of the state, by the commonly used power supply when the power supply is normal, when the common power anomalies (any one phase occur when the loss of pressure or phase), after a certain automatically after a time delay switch to backup power supply automatically returns to the common power supply, when the commonly used power is restored to normal after a certain delay; If you are using the power supply is abnormal, the controller will sound an alarm to prompts the operator to promptly repair, to ensure power supply in the long-term power supply status at any time. The alarm sound control mode "breaking" button can be turned off. Cast from the complex transfer switch control menu
The main technical parameters
◆ changeover switch applies to the rated working voltage AC400V system; ◆ changeover switch operating life (NRN cycle) 5000;
◆ automatic controller and electrical operating agencies control voltage is AC230V; ◆ Minimum convert operating time less than ≤ 3s;
◆ dual power automatic transfer switch use category, connected with breaking the conditions shown in Table.
