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
Normal operating conditions
Limits on ◆ The ambient air temperature does not exceed +40 ℃, the lower limit is not more than -5 ° C, 24h, the average does not exceed +35 ℃.
◆ the installation site altitude height of not more than 2000m.
In the ambient air temperature of +40 ℃ ◆ relative humidity of the atmosphere does not exceed 50%, lower temperatures, higher humidity; wettest month of the monthly mean minimum temperature of +25 ° C, with an average maximum relative humidity of 90%, taking into account the condensation due to humidity changes occur in the surface of the product, you should take special measures.
◆ the level of contamination level,
◆ run the place without a strong vibration and shock, corrosion of metals and destruction of insulation harmful gases, no serious dust, non-conductive particles and explosive hazardous substances, strong electromagnetic interference.
