Whats is VoR Parallel Voltage Stabilizer?

VoR is an Alternative Current (AC) voltage regulation and protection device which provides continuous, safe and stable voltage to sensitive industrial machines and equipments. It adjusts and keeps constant unstable network voltage to the most proper voltage value for industrial facilities.

How does it work?
Each VoR unit works on the principle of injecting voltage to the load supply voltage by the help of transformer connected in series between the network and load. High-speed and sensitive measuring circuits of VoR measure voltage drops and fluctuations. Microprocessor-based management board calculates the voltage value to be increased or decreased and performs the voltage injection with Thyristor switches.





The measuring time of low voltage and high voltage is 20 milliseconds.
Voltage correction time is 100-200 milliseconds.

All operations are done automatically and without any operator assistance.

Eliminate the risk with Parallel Redundant VoR

Parallel Operation Technology
VoR voltage stabilizers have power-up technology by connecting in parallel. For parallel operation, the inputs and outputs of two or more VoR voltage stabilizers are short-circuited and the communication cable between the units is attached. Parallel connected devices operate together as one device and share the load between them. The number of device which can be connected in parallel is 16. VoR voltage stabilizers which have patented parallel operation technology provide uninterrupted, safe and flexible voltage regulation solution operating together and simultaneously.

Multi-master Modular System
VoR Voltage Stabilizers do not need a separate control unit for parallel operation. All VoR Voltage Stabilizers can operate as Master. The patented VoR software protocol enables automatic selection of the master unit. When the master unit is disabled, new master is in less than a second. There is no power interruption during master change. For parallel operation, it is enough to connect the communication cable.

Equal Load Sharing
Parallel connected VoR Voltage Stabilizers share the load current. The imbalance in load sharing is less than 10%. The patented VoR software algorithm ensures that the output voltages are equal in all Stabilizers. Conductivity differences on semiconductor components are eliminated with the "Load Balancing Unit". With this technology, the total load is shared equally among the VoR Stabilizers and there is no circulation current between the stabilizers.




N+1 Redundancy Solution
VoR Voltage Stabilizers provide the N+1 redundant power solution for uninterrupted operation of critical industrial devices. For this, 1 spare VoR Stabilizer is added to the system. When any unit is shut down due to maintenance or malfunction, the remaining devices continue to operate at full power. VoR Voltage Stabilizer which is maintained can be put into use without any power interruption.

Modular and Flexible Design, Fast and Easy Installation

VoR Voltage Stabilizers provide flexible investment and planning opportunities to Industrial Enterprises, Product Suppliers and Design Engineers.

Industrial Plants, purchase VoR only in capacity that matches their existing power requirement. When needed more power, a new VoR can be added to system. When less power is required, one of the VoR Voltage Stabilizers is turned off and energy can be saved.

International Product Suppliers&Resellers, can deliver all customer requests swiftly from stock by keeping only 4 models of VoR Voltage Stabilizers in stock.

Design Engineers can easily design distribution rooms with small-sized modular VoR Voltage Stabilizers. VoR Voltage Stabilizers offer the best solution for additional power and backup needs.

Changing The Input Voltage Range

Input Voltage Correction range of VoR Voltage Stabilizers may be changed. This transaction is adjusted by changing a wiring on the power transformers. 3 different voltage range can be selected. The adjustable Input Voltage Range specification provides the great advantage for Product Suppliers and Resellers. It is not necessary to wait for customer demands for stock product order. Standard VoR Voltage Stabilizers may be customized in accordance with customer needs.






Full Protection with Fast and Durable Thyristor Technology

In VoR Voltage stabilizers, voltage increasing and voltage decreasing are done using THYRISTOR switches. Voltage regulation transaction is done from AC to AC directly. It doesn’t create harmonic distortion on network or load voltage. VoR Voltage Stabilizers are equipped with protection systems of Low Voltage, High Voltage, Overload and Over Temperature for safe operation of critical industrial devices.

Production in All Industrial Voltages (Optional)

VoR Voltage Stabilizers is produced in all industrial input voltages. 3 Phase + Neutral connection , 208VAC, 220VAC, 380VAC, 400VAC, 415VAC, 480VAC, 600VAC The nominal operating voltage of the VoR Voltage Stabilizers is determined at the order. It cannot be changed later.

Full Power Performance at Low Voltage (Optional)

Standard type VoR voltage Stabilizers are designed to operate at full load at rated input voltage. Input fuse, power transformers and thyristors of standard type VoR Voltage Stabilizers have been selected with capacities suitable for nominal voltage.



Therefore, when the input voltage drops, the output power drops at the same rate. N+1 backup solution should be used for full load operation at low voltage. For special applications, VoR Voltage Stabilizers can be produced to operate at full load at the lowest input voltage. VoR's input fuse, power transformers and thyristors are selected with capacities suitable for the minimum input voltage for continuous full load performance at the lowest input voltage.

Copper Busbar Set for Parallel Connection (Optional)

Copper busbar sets required for parallel connection of VoR Voltage Stabilizers can be ordered together with the device. Copper busbars in suitable sizes for the ordered VoR model are marked according to color codes and insulated for safe use. Screw and Bolt sets required for connection are also supplied.

Maintenance By-Pass Switch (optional)

A Maintenance By-Pass switch can be added to the VoR voltage stabilizers, which ensures that the loads are transferred to the network in case of maintenance or failure. By-Pass mode is selected from the operator panel before the maintenance bypass operation is performed. During the Maintenance By-Pass operation, the power supplied to the loads is cut for a short time.

p.s: When one of the parallel connected devices is in the by-pass position, all devices turn off their output power. Therefore, for maintenance bypass in parallel system, external by-pass board should be used.
