SZR-281, 5908312594444

Product description

3 controlled lines.
Automatic transfer switching equipment is used to control the work performance and accuracy of power lines and automatic switching power supply facility sources in the event of power line parameters decrease or total loss of voltage on the line.

Simultaneous control of three power lines
* Measured TrueRMS value
* Galvanic separation of measuring inputs lines supply
* Control voltage presence on the receiving line
* Controlling contactors or motorized connectors
* Support for an emergency exhaust generator
* Working in automatic mode, with the possibility
of determining the priority line
* Power Dump is achieved through separation of the receiving
line into two parts, with possibility to freely define
of the power dump cases
* An independent determination of voltage range for each
of the line for which line qualified as good, and the voltage
hysteresis determination of the line qualifications
* The definition of eligibility as a good line, and the time
of qualification as a bad line.
* Accelerated classification as a bad line in case of total loss
of voltage on the line
* The definition of time-controlled switching on and off
contactors / motor connector
* Ability to connect to an external safety circuit lock the controller work
* Setting and monitoring of the driver through the front panel controller with LCD display and keypad
* Setting and monitoring of the controller through a PC using a dedicated application
* Event registration with the possibility of export of the registration file to your PC
* Signalling errors achieved through contact and buzzer alarm
* Ability to controller supplying by reserve voltage 24V DC
* Settings controller access lock by a PIN code
