600 Amp Transfer Switches

RDS2-630 Electrical Panel Transfer Switch 3 Phase Changeover Switches

Overview: RDS2 Automatic Transfer Switch adopt 2 in 1 load copper terminals, easy wiring; At fire-fighting emergency, 401-404 terminals receive signal to transfer to "O" position; Optional B/E/G/F built-in control modules, optional LCD display, it's logic settings are programmable, over/under voltage/ frequency protection, transfer delay timers, engine exerciser timers, and fault transfer to "O" position at intelligent E module (A phase must be normal, otherwise this function is disabled). CE certified. AC-32B utilization category per IEC/EN 60947-6-1 standard.

Performance And Characteristic

● RDS2 Automatic Transfer Switches adopt double complex contact, horizontal pulling mechanism, micro motor energy pre-storage and micro-computer control technology, achieving zero arc (no arcing chamber);

● Reliable mechanical interlock and electric interlock, using disconnect switches as executive unit, makes the automatic transfer switch more reliable and safety;

● Emergency "O" position, it can be command transfer to double off "O" position under emergency situation, remotely cut off source I and source II power supply, meet fire linkage requirements;

● The transfer operation is motorized by single motor, reliable and smoothly on transition, noiseless, slight vibration;

● The drive motor only passes current during load isolation switch transition, steady-state operation does not need to provide working current, significantly saves energy.

● Executive load disconnect switch have mechanical interlock, ensure reliable operation of the main/backup power supply without interference.

● Distinct ON and OFF position indicator, padlock and etc., reliable isolation between power supply and load.

● High security, high automatization, high reliability, working life more than 8000 times;

● Mechatronics design, transfer operation is accurate, flexible and smooth, adopting international advanced logic control technology, strong anti-interference ability, and no external interference.

● Three working position (I-o-II): main power ON, backup power OFF; main power OFF, backup power ON; main and backup power OFF; ;

● Easy to install, control circuits adopt plug type terminal connection;

● Three operating functions: emergency manual, emergency OFF(fire-linkage), auto control by built-in controller logic.

Basic Type Switch Control Characteristic

● Applied to two power supply system;

● Auto, Remote, Manual control functions;

● 0.5s transfer delay timer, avoiding miss transition due to voltage unstable;

● Key switch select the operating mode(Auto/Manual);

● Optional RS-485 communication port.
