Yueqing double-pass, only Thai company Shanghai dual power switch kind of two-way division of Yueqing Electric Company STQ5 Isolated dual power switch products are 30A, 60A, 100A, 150A, 300A, 400A, 500A, 600A, 800A, 1000A, 1200A, 1400A , 1800A, 2000A, 3000A; Thai Industries Limited STQ4 end dual power switch products Shanghai stop there: 400A, 600A, 800A, 1000A, 1200A, 1400A, 2000A, 2500A, 3200A, 4000A; double-pass, only Thai company STQ2 Economical dual power switch products are:. 100A, 200A, 400A STQ5 isolated six dual power switch product features 1) sufficient contact time dual power switch is open, in order to avoid arcing may occur during the conversion process is discharged. 2) ensure that the contact pressure plate spring constant, and therefore conductivity constant contact in case of voltage conversion. 3) because of the presence of a mechanical locking device, after the conversion, no operating current. 4) contact silicon alloy dual power switch price, highly resistant to burning 5) when the switch is running, every contact from the sliding contacts can be cleaned of dust and oxidation 6) Kyoritsu STQ5 series dual power switch time conversion rating:.. MZ is 30ms ~ 80ms, ES for 3 ~ 8ms; can meet the requirements of high computer control systems, communication systems, and medical equipment such as two-way power switch when the dual power switch device to "Auto (AUTO)" position, the system will be automatically switched state: 1.0. Under normal conditions, (U1 and U2 supply voltages are normal), then disconnect the tie breaker Q3, Q1 and Q2 breaker is closed; 2.0 when the supply voltage loss U1, U2 supply voltage is normal, and the tie breaker Q3 is off open state, the circuit breaker Q1 disconnect delay after t1, the tie breaker breaker Q1 Q3 after delay t2 closed off by a high-quality dual power switch suppliers, the two-way power provided by the power supply U2 ; 3.0 U1 when the power returns to normal, the tie breaker Q3 disconnect delay after t3 dual power switch, circuit breaker Q1 Q3 after the tie breaker is closed off by the delay t4; 4.0 U2 when the power loss of pressure Power U1 voltage is normal and the tie breaker Q3 is off, then disconnect breaker Q2 delayed by t1, the tie breaker in the breaker Q2 Q3 disconnect delay after t2 is closed, the two-way power U1 provided by the power supply; 5.0 U2 when the power returns to normal, the tie breaker Q3 breaker disconnect delay after t3 Q2 Q3 after the tie breaker is closed off by the delay t4. 6.0 In shutdown mode, the system does not consider the U1 and U2 supply voltage is normal, the breaker Q1 / Q2 and Q3 will be the tie breaker in the OFF state. t1: from the power U1 (or U2) loss of pressure to the breaker Q1 (or Q2) off delay time t2: disconnected from the circuit-breaker Q1 (or Q2), power supply U2 (or U1) normal to the tie breaker Q3 closed delay time t3: Recovering from power U1 (or U2) normal to the tie breaker Q3 off delay time t4: Disconnect from the tie breaker to breaker Q3 Q1 (or Q2) closed extension When the time delay in the time range, DPT / TE has to return properties.
