RDQ3NMB ATS Generator Automatic Power Switch Automatic Transfer Switches
Basic Structure
RDQ3NM series intelligent ATS is comprised with two 3P or 4P MCCB and its accessories (Aux, contact, Alarm contact), Mechanical interlocking transmission mechanism, intelligent controller etc. It has 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.
The Features:
● There is a reliable mechanical interlock device and electric interlock protection between two MCCB, completely avoid the possibility of two MCCB being closed at same time;
● Intelligentized controller adopts the single chip microcomputer (SCM) as the control core, simple hardware, strong functions, easy extension and high reliability;
● Intelligent controller circuit layout design adopts power sampling separated with SCM control, from the hardware to overcome the electromagnetic interference;
● With short circuit, over load protection functions, over-volt & under-volt, phase missing auto transfer function and intelligent alarm function;
● Auto transfer data by external setting freely, with operation motor protect function;
● Signal connecting cable have passed FLUKE instrument channel test, anti near crosstalk, attenuation crosstalk and back wave loss, can meet the test criteria for permanent link;
● The ATS controller installation method provide customer with highly autonomy, split installation only need simply connect the attached RJ45 signal cable to the corresponding terminal port;
● The controller part based on the previous similar product, have made enhancement process of the electronic components, make it more matching with the product operation.
● Product appearance lead in international design concept, more elegant and practical.
● Mechanism innovation made following improvements:
 | Controller Functions 1. Auto mode indication; 2. Manual mode indication; 3. Fault indication: When ATS is fault or load short circuit causes the circuit breaker trip, this indicator will lighten; 4. Main power voltage data indication zone : under working status, it display the main power voltage and time delay, under setting status, it display the item code; 5. Main power circuit breaker ON/OFF indicate; 6. Setting status indicate; 7. Backup Power circuit breaker ON/OFF indicate; 8. Fire linkage function start indicate; 9. Main power voltage, time and frequency unit; 10. A, B, C phase indicate; 11. Backup power voltage, time and frequency unit; 12. Backup power voltage data indication zone: under working status, it display the backup power voltage and time delay, under setting; status, it display the item code; 13. Generator start signal indicate; 14. Auto/Manual mode select button: under working status it used to select the Auto and Manual mode, under the setting status it used as save and escape function; 15. Main power transfer button: under manual control mode and main power good, push this button will forced to transfer to main power; Under setting status, it used for up page button; 16. Backup power transfer button: under manual control mode and backup power good, push this button will forced to transfer to backup power; Under setting status, it used for down page button; 17. Trip button: under manual control mode if any one of the two power is good, push this button will change to OFF position; under setting status it is used for data reduce button; 18. Fault inquiry button: if the fault indicator is lighten on the display, through this button can check the fault code; under setting status it is used for data increase button; 19. Setting button: push this button will enter into the controller setting menu. |
Terminal Wiring Instruction
400 Amp Automatic Transfer Switches have smaller size and is easy to install, space saving
Adopt modular design, operating unit, transmission mechanism , control circuit fully independent, easy for replacement;
Mechanical interlock device use gear transmission, avoid two MCB close at same time; Controller power supply and power source sampling power are separated from SCM control system, from the hardware design to overcome the EMI.
Reliable mechanical interlock device and electrical interlock protection, avoid two MCCB closing at same time; Controller power supply and power source sampling power are separated from SCM control system, from the hardware design to overcome the EMI;
Controller display panel removable can be separately installed, to match different installation requirements; Frame current: 63, 125, 250, 400, 630, 800, 1250A
