Control characteristics switch has three poles, four poles (three pole + neutral pole can be off) products. Divided 16A, 20A, 25A, 32A, 40A, 50A, 63A, 80A, 100A, 125A, 160A, 200A, 225A, 250A, 315A, 350A, 400A, 450A, 500A, 630A, 800A, 1000A, 1250A, 1600A, 2000A, 2500A, 3200A, 27 current levels. The basic types: primary - backup power, automatic recovery. Type Ⅰ: 100A less electricity - electricity, automatic recovery, two-way power three-phase phase detection; 125A above, mains - mains, standby or mutual standby selectable from the cast, two three-phase power supply testing. Ⅱ type: Mains - mains, standby or mutual standby optional PC-class dual power switch, two-way power three-phase phase, over undervoltage detection. Ⅲ type: Mains - oil machine, automatic recovery, two-way power three-phase phase Zhejiang dual power switch, over-under voltage, oil-frequency detection. Electric double-pass dual power switch control features: 1.100A following: A, suitable for two-way mains standby system; B, when the mains supply fails (power failure or phase) switch by the delay (can be set to 1 -16s) is automatically put into the standby power supply circuit. C, 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. 2.125A above: A, suitable for two-way mains standby system or mutual backup systems. B, when the switch to select automatic recovery function (ie primary and secondary type), C, switch to select when no self-recovery function (ie, mutual backup type) 3. Select the preferred power supply circuit for self-administration by plug terminals. STQ1 new dual power switch structure principle device uses STQ1 new dual power controllers and contactors do two generic composition CB-level dual power switching devices used in emergency lighting, power distribution box, you can achieve a reliable emergency lighting, power distribution box Dual line supply automatic switching function, but also can fully play the advantages of long life, small size contactors, suitable for use in emergency lighting power distribution box, and there QTS1 new dual-power controllers and two general purpose contactors do Composition Class CC dual power switching devices by the national quality inspection departments inspected in accordance with the national standard "GB / T14048.11-2002", is in line with national standards of qualified products to overcome the early use of intermediate relays and contactors lap of a line of dual power switching scheme does not meet the national standard shortcomings. STQ1 new dual power switch designs Selection Method: This dual power automatic switching scheme is automatically switched by a STQ1 dual power controllers and contactors composed of two generic ATS dual power switch, contactor manufacturers can be used at home and abroad production of a variety of contacts, designers can choose according to need, the controller model all QTS1-K-A1.5 indicate to which QTS1-K is a model without moving dual power switch, A denotes vote since complex type (generally used for this type), is to switch from the usual 1.5 represents the standby power supply switching delay time is 1.5 seconds, depending on the needs of designers on the lower level ATSE fit and adjust the operating time of 1.5 seconds to suitable for most systems, under normal circumstances do not need to be adjusted. ATS dual power switch | Double-Electric (certified) | dual power switch only by the Thai Industrial Co., Ltd. Shanghai Branch Yueqing offer. Shanghai only Thai Industrial Co., Ltd. Yueqing Branch (www.cnats.cc) is Wenzhou, Zhejiang Province, switch leaders, over the years, the company is implementing the scientific management, innovation and development, the principle of honesty and trustworthiness, and satisfy customer needs.
