STQ2 automatic power switch is mainly composed of the basic structure of the implementation of the power conversion circuit breaker composition, there are three state switching positions for users to choose: the common power supply (N) together, double points dual power automatic transfer switch, standby power (R) together, the switch has small size, light weight, stable, easy to use and so on. STQ2 automatic power switch using the operation regardless of whether the common power supply and backup power supply voltage, can use the manual mode of operation. In manual operation, manual and automatic button should be placed in manual position, when pushing the handle clockwise to the end dual power switch professional manufacturer of standby power Qr execution breaker opening, common power supply execution breaker QN closing; When pushing the handle counterclockwise to the terminal, the standby power circuit breaker QR closing execute, execute common power supply breaker QN opening. Warnings 1. not with plug controller plug, otherwise it will cause an electric shock or product damage. 2. The non-professionals to prohibit the operation or modification, or they will cause an electric shock or product damage. 3. This product users without changes, this will cause damage to the product. 4. Load capacity can not exceed the rated capacity of the switch, otherwise it will lead to switch tripped or burned. 5. Do not be neutral (n) mistakenly access phase, two circuit breakers input must be consistent with the choice of three-pole circuit breaker. 6. can not be directly installed in outdoor work. 7. not be installed directly in explosive, moisture, direct sunlight, high temperature, vibration, shock and other places. 8. can not be directly installed in a conductive dust. 9. The sample should meet the requirements of Shanghai dual power switch, otherwise it will shorten life. Medical isolation dual power switch specifications and configuration medical isolated power supply cabinet for the needs of the medical class two places designed distribution cabinet with local IT systems dual power switch, IT systems installed insulation monitoring device to monitor the system insulation the status of each output circuit breaker with a short-circuit protection functions; other system output circuit breaker is adopted with leakage protection function. Thai Industrial Co. only five series dual power switch products successfully used in hospital health care system 1. Isolated dual power switch: for hospital ICU / CCU ward IT systems provide safe and reliable power supply isolation, and have IT systems Insulation monitoring. 2. Swatch dual power switch: to provide security for the hospital operating room perfect for all types of power solutions to provide secure and reliable IT systems isolated power supply as an important surgical equipment, and has an IT system insulation monitoring and has to IT systems are monitored insulation resistance, 3. isolation transformer load current, real-time monitoring of transformer winding temperature and fault alarm. 4. Mini Dual Power Switch: The instrument-specific DC power modules, rail mounting, with insulation resistance, transformer load rate real-time display; can remotely set the alarm type insulation monitor thresholds, and STQ4 supporting the use of dual power switch Protection type current transformer. The maximum measured current is 50A, variable ratio of 2000: 1 5.
