Features

Short description

T changeover switch is designed to transfer loads automaticallyhis an microprocessor based PC class device

and manually from one power source to another in a wide variety of 1-3 phase applications.

The unit monitors 3-phase normal and reserve source voltages, sends remote start command to the

generating set and performs changeover switching between those 2 sources connecting the load circuits to a

power source having voltage and frequency within preset limits.

Device has a manual load switch lever, a manual/auto mode switch and a mechanical locking switch.

Inputs and outputs: fire linkage control, generator remote start, external indicators.

The front panel leds provide information about mains and generator power availability as well as a current

switch position.

The device display control panel shows device current state and source voltages and frequences and can be

placed on the switch front side or in a distance of 1-3 meters from the device via standard Ethernet cable.

Power source voltage/frequency limits, transfer/start/stop delays, generator exerciser schedule and transfer

modes are front panel configurable.

Note: The delays apply in case if the device is connected to 24VDC auxiliary power supply only.

• High density silver-alloy contacts providing thousands operating cycles at 100% rated load;

• Bridge type double break design not requiring special SCPD and matching AC-33B requirements;

• Optimized magnetic blow-out arc extinquish system allowing to reach 10le capacity;

• Multi-mode operation including manual transfer, automatic transfer with/without autorecovery and

generator control under various configuration settings;

• 3 working positions: main power ON - backup power OFF; main power OFF - backup power ON; main and

backup power OFF;

• Microprocessor controlled operations;

• Reliable mechanical interlock and electric interlock;

• "Zero Position" technology. Device can be set to Zero Position under emergency situations with two way

power supply cut off meeting the fire fighting linkage requirements;

• Singleness motor drive providing smooth, reliable, low noise operation;

• Driving motor energized during switching operations only and having outstanding energy saving;

• Mechanical interlock, making sure that the Normal power and Reserve Power sources work without

interference;

• Distinct ON and OFF positions and activity indicators;

• Electromechanical integration design with accurate changeover adopting an advanced logical control

technology and high anti-interference ability;

• Easy installation using control circuit plug type terminal connections.
