Haida Limited provides you HZQ51 soar dual power

Haida Limited provides you HZQ5 soar dual power. ◆ ambient air temperature is -25 ℃ ~ + 40 ℃, the average of 24 hours and not more than + 35 ℃ ◆ maximum temperature + 40 ℃ relative humidity less than 50%, lower temperature allows a higher relative humidity, for example, 90% + 20 ℃, but should take into account changes in temperature may produce condensation phenomenon ◆ installation site altitude does not exceed 2000m ◆ ◆ category Ⅳ class gradient is not greater than ± 23 ° ◆ Pollution level 3 ◆ If these conditions are not met, the order should be in consultation with the manufacturer, this switch is used for offshore oil and nuclear power plants should be separately signed a technical agreement on technical requirements ◆ automatic transmission, when the common power supply, undervoltage, overvoltage, loss of pressure transition to standby power; when the same standby power failure occurs, the conversion to double points position, while the display shows the automatic alarm ◆ LCD screen protector 30s, the display screen button the first time, the second time to enter the position, enter Setting a password is required when manually set input ◆ garbled (crash) when the reset button to reset to the default values ??set ◆ When the controller is set in automatic, manual position, press the controller panel display shows the double points double points, but do not ◆ alarm time delay switch controller settings back to normal when the power fails in the value of the set, dual power switch is not, contrary to switch structural features and functions ◆ HZQ5 type A · T · S as the main dual power automatic switch equipment using electromagnetic drive, electrical machinery while interlocking mechanism, the main circuit contact for static and dynamic structure, moving contact V-shaped design. To avoid long solenoid energized, closing the use of electric, mechanical retention, self-control power are cited prepare current exchange 220V (without additional control current). Because of the structural characteristics of the superior, so standby power will not be turned on simultaneously, to ensure common, reliable backup power, mutual non-interference. Switch electrical or mechanical closing instructions, and can provide customers with passive normally open normally closed auxiliary contact for customers other purposes while providing intelligent controller ◆ with overvoltage, phase control, undervoltage, delay control, generator control, fire reset, the feedback signal and many other features, and anti-interference ability ◆ with automatic recovery, since the vote of no self-recovery, backup each other three operating modes; together with a common power supply, standby power points; common power points, standby power together; common power points, standby power in three steady state ◆ easy to install, control circuit using plug-in terminal connection; available in manual mode special handle for manual conversion
