What is AVS Adjustable Voltage Source?

AVS Voltage Source is an AC Power supply whose Output Voltage can be adjusted.
In AVS produced with thyristor technology, voltage changes are made without interruption. Voltage switching can be done under full load.
In standard devices, the output voltage can be adjusted from 0V to 2 times of nominal input voltage. Output voltage range can be changed for special projects.



In the AVS Voltage Source voltage adjustment is made directly from AC to AC. There is no AC/DC, DC/AC Voltage conversion.
Therefore, it does not generate electromagnetic noise or harmonic noise on the input or output side.
It can work with the same high performance in all inductive, capacitive, non-linear loads.
It is used in continuous operation and performance tests of electrical devices and machines at different voltages in laboratories or production lines.
AVS voltage source has Soft-Start feature. The output voltage drops or rises to the value set by the operator at the speed selected by the operator.
In the AVS voltage source, the output voltage adjustment is made independently for each phase.

Applications
  • Laboratories
  • R&D Centers
  • Serial production lines
  • Industrial Machine manufacturers
  • Electronic device manufacturers
Reliable, Independent, Flexible Power Supply

Design Features

The AVS Voltage Source is designed to operate at all industrial voltages. The supply voltage of the control units is separate and independent from the test voltage.
Test voltages of AVS voltage source are 3 Phase + Neutral, 208VAC, 220VAC, 380VAC, 400VAC, 415VAC, 480VAC.
The AVS voltage source can operate at frequencies of 50Hz and 60Hz. Input frequency and output frequency are always the same, there is no frequency change feature.

Expanding systems with parallel connection

Parallel Connection Technology (Optional)

AVS voltage source has a power boost feature by connecting in parallel. This feature is optional and can be added during production.
For parallel operation; The inputs and outputs of 2 or more AVS voltage sources with the same technical specifications are short-circuited and the communication cable between the devices is attached. Parallel connected devices work together as one device and share the load between them. The maximum number of devices that can be connected in parallel is 16 pcs. AVS voltage sources with patented parallel connection technology work together and simultaneously to provide a very high power, uninterrupted and safe adjustable AC power supply solution.

Multi-master Modular System (Only for AVS with parallel connection)

There is no need for a separate master unit to operate AVS voltage sources in parallel. All AVS voltage sources can operate as master. With the patented software protocol, the master unit is selected automatically. A new master is selected in less than a second when the master unit is disabled. No Power interruption during master change. For parallel operation, it is sufficient to connect the communication cable.

AVS Voltage Sources have an ergonomic and user-friendly Operator Panel designed for management and monitoring.

All operating parameters can be monitored from this panel and some operating parameters can be adjusted. There is two-step password protection for parameter changing.

Monitorable parameters: Input Voltages, AC Output Voltage, Output Current, Operating Frequency, Date-Time, Device status information, Fault and error codes. (In models with parallel connection feature, Device ID number, Number of devices connected in parallel, communication information)

Changeable Parameters: Rated Input Voltage, Output Voltage Set Value, Soft-Start Speed, Output Current Setting, Automatic Test Duration, Communication parameters, Date-Time information.
