STQ5 dual power automatic transfer switch technology parameters introduced (1) STQ5 Shanghai for two-stage automatic transfer switch dual power accessories, spare parts, when the switch is connected to the switching signal does not stop in the middle of the open position immediately change from one power supply to another power level of electrical current specifications of only 20A-500A (2) STQ5A series switches for the PC level. (3) rated working voltage AC660V / 690V and DC125V250V following control voltage AC380V / 400V, 100V, 270V, and DC125V / 250V, etc. Other voltage switch electrical specifications for the special delivery. order stating. (4) communication interface functions for special orders with Willow City dual power accessories, shall specify when ordering. (5) 500A and below the front panel switch is generally wiring, 630A and above the rear panel switch is generally wiring, in addition to the special supplier works STQ5 dual power automatic transfer switch device is mainly used to control and automatic switching low voltage circuit breakers with two mechanical and electrical interlock: a 4 position switch for setting the four operating modes: Auto mode: switch set to "Auto (AUTO)" position normal power mode: switch to "normal (NET)" The emergency power supply mode: switch to "Emergency (EMER) "location shutdown mode: switch in the" off (OFF) "position when the system is put into operation, the need to run the switch to" run (RUN) "position, while the" reset (RESET) "button the application will run back to the initial state. Why dual power device manufacturers to produce Swatch dual power automatic switching device product? In programming, the effort to make it standardized, modular, easy Swatch dual power switch products in the future upgrade. Program consists of initialization, signal acquisition, judgment conditions, the composition of the working status outputs, power output switching and computing routines of several parts. After the device is powered by the self-resetting circuit initialization and reset the device to enter the program, mainly on the functional registers and flags are set. Detection input power supply is normal, select the normal power supply output by the LED LED indicates working status. Swatch detecting dual power switch failure and recovery added to determine the concept of humane management, such as: when the main power supply, if it detects a fault will keep the main power switch to the auxiliary power supply, in order to protect downhole monitoring equipment work properly. If the auxiliary power supply, when the main power is restored, the unit will not switch immediately to the main power supply to the main power several times but continued to judge whether it is normal dual power accessories, dual power accessories prices, to avoid the fluctuation of the main power generated at the time of recovery adversely affect the normal operation of the detection equipment. If two power supplies are not working, once detected, the main power supply is normal immediately cut the main power supply downhole monitoring equipment to ensure monitoring equipment supply needs. According to the technical program, design and manufacture of a dual power supply automatic switching devices.
