Scope STQ2Z series dual power automatic transfer switch (hereinafter referred to as ATS) There are two basic company KCM1 series circuit breaker with high self-developed sub-capacity dual power automatic switch controller, etc., applicable to the rated voltage 400V.50Hz dual power switch, rated current 800A and below the high-rise buildings, hospitals, shopping malls, banks, fire, chemical, Qia gold, military facilities, etc. are not allowed off a class load, part II load, complete double-loop power supply system Auto power conversion, thus ensuring reliability of supply important users. This product complies with GB / T14048.11-2002IEC60947-6-1 (1998) "Automatic Transfer Switching Equipment" standard. Use of the environment: ATS dual power automatic transfer switch should be installed in non-conductive dust and corrosive, explosive, flammable gases in a dry environment, and should avoid the rain and water, the device can not be subjected to shock and vibration, which is mounted vertical ramp of not more than 5 degrees, ATS external magnetic field installation place, in any direction should not exceed 5 times the geomagnetic field. Selective example STQ2Z-100 / 4.Ⅲ-380Vin50A automatic transfer switch, thermal current 100 amps, 380 volts AC rated voltage, rated current of 50 amps, 4-pole (3-pole + neutral pole can be off) WATSG dual power conversion switch for mains - automatic recovery oil-supply system. Ⅱ type dual power switch control features: 1. Applicable to standby system or mutual backup systems of two mains. 2. Switch selection for automatic recovery features intelligent dual power switch, when the mains supply fails (phase, over voltage); switch by the delay (can be set 1-16s) is automatically put into the standby power supply circuit; When the main circuit returns to normal, the switch by the delay (can be set 1-250s) automatically switches back to the main power supply circuit. 3. switch to select from the vote when no self-recovery function, when a power failure Ⅰ Road (phase, over voltage); switch by the delay (can be set 1-16s) automatically into Ⅱ way power circuit; when Ⅰ When the road back to normal power supply circuit, the switch does not cut back Ⅰ Road Ⅱ road only when the power circuit fails, the switch by the delay (can be set 1-250s) automatically switch back Ⅰ way power circuits. 4. Plug the power supply terminal selection priority circuit (125A and above). Ⅲ dual power switch control features: 1, applies to the main electricity supply, generators for backup power systems. 2, when the mains fails, the switch controller first sends a signal to start oil machine, switching delay after 3S Shanghai People's dual power switch, switch to invest in "O" for, and then by the delay (warm-up time is adjustable 1 -250S) automatically into the oil-supply circuit. 3, when the utility power is restored to normal, the switch by the delay (can be set 1-250S) automatically switches back to the mains supply, then delay (settable 1-250S), the controller sends a signal close oil machine. 4, electricity, oil-phase three-phase, three-phase over under voltage detection, oil-frequency detection function over four two power switches have: ① automatic, remote control, manual control functions ② detection delay 0.5S signal to prevent malfunction. ③ automatic state with remote control "O" position. ④ key switch to select the operating mode. ⑤ can be equipped with RS-485 communication interface (optional), can be configured according to user needs.
