Control Panel Functions

• 1
  Main power indicator light When main power voltage normal, this indicator lighten.
• 2
  Backup power indicator light When backup power normal, this indicator lighten.
• 3
  Main power ON indicator light When switch on the main power position, this indicator lighten; when during the switch recovery delay status, this indicator flickering.
• 4
  Backup power ON indicator light When switch on the backup power position, this indicator lighten; when during the transfer delay status, this indicator flickering.
• 5
  Auto/Manual transfer mode control switch When switch on left side is Auto transfer mode, on the right side is manual transfer mode.
• 6
  Transfer delay time setting potentiometer Main power to backup power transfer delay time (A/C type without, B/D type have). When ATS is on main power ON position, if main power fault and backup power normal, controller start the timing ( the time setting by transfer delay potentiometer), after the timing is over then controller start transfer to the backup power supply; When setting longer time delay can avoid switch transfer due to power grid instant voltage drop ( for example, there is a big size motor start in the same power grid, will cause the voltage drop in a short time period).
• 7
  Recovery time delay setting potentiometer Backup power to main power transfer delay time (A/C type without, B/D type have). When ATS is on backup power ON position, if main power recovery and normal, controller start the timing ( the time setting by the recovery delay potentiometer), after the timing is over then controller start transfer to the main power supply.

About ATS & Product Structure

About ATS

RDQ3NX-A/B/C/D series ATS was introduced to the market in 2009, effectively solving the problems of MCB type ATS's insufficient functions, poor reliability, inconvenient replacement etc. This product has three patent certificates (Invention patent, Utility models patent, Appearance patent). C/D series is a new type introduced to the market in 2010. This product has complete functions, concept innovation, and is a unique product among similar products.

Product Structure

RDQ3-63-A/B/C/D series ATS is comprised of two MCB and accessories, mechanical interlock system, intelligent controller etc. The product has A, B, C, D four type control constructions. A type is the basic type (Only provided with auto change auto recovery, phase missing protect, auto/manual control). B type is the intelligent type (including the A type functions and has Generator start, fire linkage, time delay functions). C and D types are improved types, with increased three-phase voltage monitoring functions on A and B types. This ATS series circuit breaker keeps the original breaker's overload and short circuit protection function.

RDQ3NX Series Advantages

• Product with modularized design, executive unit, transmission mechanism, control circuit completely independent, easy for replacement.
• Mechanical transmission device adopts gear transmission, completely eliminating the possibility of closing at the same time.
• Compact appearance, it is one of the smallest products on the market.
• The control circuit layout adopts working power and sampling power separate with single chip control, to overcome the electromagnetic interference from the hardware construction.
• Working power voltage range: AC200-400V.
• Less power consumption, max. peak power loss 4.8W, only 20% of other similar products.
• Product has complete functions, with generator start, fire linkage, ON delay functions etc.
• Modularized design, good components interchange performance, easy installation.
• Can use various executive circuit breakers.
