Description
DVQ1 Dual Power ATS is a fully new product of our company, by organizes top engineers in two years research and development, grand launch at the end of 2014, completely subvert the traditional dual power ATS design style, leading in the international industrial design concept in the design process, from the product structure, appearance, ergonomia, and control circuit etc., comprehensive improvement of the traditional ATS, so as to make it has the quality of international firs-class products and with high competitive price.
DVQ1 series intelligent dual power auto transfer switch (brief as ATS) suitable for emergency power supply system with rated AC voltage 400V 50/60Hz. When one power source fault, can auto interchange from main power to backup power, no need manual operation, to protect the power supply stability. Mainly apply to the important place which not allow power cutoff such as Hospital, shopping mall, bank, chemical industry metallurgy, high building, military facilities and fire-fighting etc. Product accord with standard of IEC60947-6-1: <Auto transfer switch >. < Civil high building fire-fighting standard>, <High building fire-fighting standard > < Civil building electric design standard > etc.
Use Condition
2.1Ambient temperature: -20°C – +40″C; 24hours average not more than +35°C;
2.2Atmospheric conditions: humidity not more than 50% at max. +40″C, higher humidity is allowed at lower temperature, at most wet month, the average max humidity is 90% at the average min temperature +25°C, and have considered the condensation on the product surface due to temperature variation.
2.3Altitude: not more than 2000m;
2.4Pollution class: the installation site environment pollution class 3.
Controller Functions
7.1This product adopt B type controller;
7.2Can set the controller working mode and transfer data by the control button;
7.3Through the display can directly read the measuring and control data, including the voltage and delay time etc.
7.4Fire linkage control function: Controller with a set of passive fire-fighting signal input terminal. The input signal using opto-coupler isolation, have strong anti-interference ability; And also have a set of passive feedback signal output terminals, can send the switching position back to fire-fighting control equipment.
7.5Generator start/stop control function: Controller with a relay contact point to control the generator start and stop, and also can manually setting the generator starVstop delay time (need connect a aux. power with DC15-30V);
7.6Can remove the display panel and install on the switchgear panel, users can observe the ATS status without open the switchgear doors.
Basic Structure
DVQ1series intelligent ATS comprised with tw0 3P or 4P MCCB and its accessories (Aux. contact. Alarm contact), mechanical inter-locking transmission mechanism, intelligent controller etc. Have integral and split type two structures. Integral type is controller and executive unit installed at a same base; Split type is controller installed on the panel and the executive unit installed on the base inside the panel box, a 2m length signal cable connecting the controller with the executive unit.
Working Mode
4.1DVQ1 series intelligent dual power ATS have two working mode: Auto mode and Manual mode.
4.2Auto mode: DVQ1 series ATS according to the controller functions have three modes: Auto change Auto recovery (R) Auto change no auto-recovery (S) and Power Grid-Generator (F), the first two mode used in power grid-power grid system, the latter mode is used in power grid-generator system.
4.3Manual mode: manual mode has three working mode, main power, backup power and breaker trip modes. Under manual working mode, there will be no auto transfer function.
•Main power mode: Forced disconnecting backup power, and turn ON the main power;
•Backup power mode: Forced disconnecting the main power and turn ON the backup power;
•Breaker trip mode: To disconnecting two power sources, also can switch on the fault tripped circuit breaker.
