Special for Chint intelligent dual power NZ7-225 / 3P automatic transfer switch

Dual Power Supply CHINT NZ7-225 / 3P series, supply all brands of all types dual power NZ7 dual power automatic transfer switch NZ7 Molded dual power automatic switching system for AC 50 / 60Hz, rated voltage 400V, rated current 1250A below dual power supply system that can automatically switch (can also be set for manual switching) common power supply (N) and standby power (R) between the dual power supply so that the user unattended substation. This product is suitable for power does not allow an important place of high-rise buildings, residential areas, military facilities, hospitals, airports, terminals, shopping malls, communications, fire, metallurgy, chemicals, textiles, petroleum, coal, etc; mechatronics design, high current, structure Simple, fast switching hearing; switching mode, the function can meet a variety of applications, power grid, power generator, automatic recovery, since the vote of no self-recovery and so on. Product Features 1. double row structure composite contacts, cross-fit bodies, micro-motors pre-storage 2. microelectronic control technology, the basic realization of zero-arcing (no arc chute) 3. The use of reliable mechanical interlock and 4. The use of electrical interlock technology 5. zero-bit technology has obvious off position indicator, padlock reliability features high isolation, achieve reliable power supply and the load among more than 8000 times the life 6. mechatronic design, switching accurate, flexible and reliable electromagnetic compatibility is good, anti-interference ability, without external interference, high automation 7. automatic type without external appearance of any control components, small size, light weight by the logic control board, with different logic to manage mounted directly on the switch of the motor, the transmission-line operation to ensure that the dynamic switch position. Motor for the neoprene insulation damp motors equipped with safety equipment, trips beyond 110 ℃ humidity and over-current condition. In the fault disappears after work automatically, reversible reduction gear with straight gear. Normal working conditions: temperature ● Installation space environment -20-40 ℃. ● elevation: the installation site altitude does not exceed 2000m.
