Infinite Life ...
Datadigital-SVR is a static voltage regulator with no moving parts in the static voltage regulators. Voltage regulation is performed entirely by microcontroller-controlled digital technology for milliseconds. There is no part to wear, no need to care for the old clothes. |
In conventional dc motor voltage regulators, however, mechanical friction parts such as motor collectors, variable transformer brushes, brush beds show rapid wear. In continuous operation under load, heat and abrasions on the transformer surface and even voltage interruptions occur. |
High Reliability ...
Datadigital-SVR, Static Voltage Regulators are totally microcontroller controlled, thyristor controlled and working with digital technology. Protect itself and the load it is carrying in abnormal conditions such as overcurrent, overheat and short circuit of the output when the mains voltage is dangerously low and high. RFI and EMI filters are available as standard at all powers. |
However, in classical dc motor voltage regulators; the rectification of the varying mains voltage is provided by adjusting the output voltage of the variable transformer of the brush driven by a motor. This refers to slower response to wear and fast mains voltage changes. Because the output voltage correction speed is in the order of a second, it is considered to be very slow for modern electronic devices. |
Very High Correction Rate ...
Datadigital-SVR, Static Voltage Regulators senses the change in tension during the first period of the network and puts the output voltage at 220V + 2% in one period (20 milliseconds). |
On the other hand, in the case of dc-motor voltage regulators, even when an asynchronous motor is started, very high temperature will occur due to the contact resistance at the contact point of the brush, and the surface of the brush and varactor transformer will be damaged. |
High Starting Current ...
Datadigital-SVR, Static Voltage Regulators respond quickly to loads that require high starting current thanks to semiconductor elements (thyristor) which are resistant to sudden and high currents. These semi-conductor elements can withstand 10 times the nominal current for 20 milliseconds.
No Distortion ...
Datadigital-SVR, Static Voltage regulators realize voltage regulation with static elements (thyristor) in ZERO TRANSFER logic by STEP_UP / DOWN method. Current transfer is zero transition. Therefore, it does not contain harmonics
Overvoltage-undervoltage protection
limits the maximum and minimum voltage values that go to the receiver connected to the device. The user can control the time to cut off the voltage to the receiver in case of exceeding these values and values by controlling the front panel.
Protection against overcurrent-output short-circuit protection:
Protection is achieved by inspecting the nominal currents drawn by the device under test, exceeding the set current tolerance values, exceeding the current and time graphs and the difference in the table values of the current rise speed.
SAG-SURGE Protection;
The network is an "effective protection circuit" that protects buyers against sudden collapse, rise and thousands of volts of jumps occurring in microseconds. The Effective Protection circuit generally operates in the form of symmetrical and asymmetric voltage ramps.
Effective protection circuit; three-stage protection circuit consisting of fast reacting suppressor diodes, medium protection stage with varistors and coarse protection with strong gas overvoltage transmitters. The protection phases are separated by ohmic resistances. This ensures that the overcurrent is delimited by suppressing the overvoltages and the power is dissipated optimally in the protection circuit when the impulse currents need to be diverted. Thus, effective protection is ensured in such a way that it is not possible to get over-voltage from the network to the receiver. |
Working Principle
DC-Control consists of voltage regulator, troidal transformer (variac) which provides regulation, auxiliary transformer and electronic circuit which controls variable transformer control dc motor according to output voltage. With a control system that includes a fast response time, the DC motor train with high starting torque will quickly correct even small changes in voltage at the start. When the servo-motor input voltage goes out of the operating limits, the limit switch switches the output voltage automatically to the desired value and is deactivated by the control circuit. When the regulation is completed, the motor is de-energized with the help of the electronic braking circuit and it runs quietly.
