TDGC2J Single Phase Contact Voltage Regulator

The Yibaling TDGC2J single phase contact voltage regulator is a classic mechanical manual voltage regulation device. The core consists of a ring-shaped iron core and a carbon brush sliding contact structure.
By rotating the handwheel, the carbon brush moves along the surface of the winding, enabling continuous and smooth adjustment of the output voltage within the range of 0-250V (or custom range).
It has a simple and sturdy structure, with rated capacities ranging from 0.5kVA to 10kVA and other common specifications. The TDGC2J voltage regulator features strong overload capacity, intuitive adjustment, and convenient maintenance.
During operation, the carbon brushes directly contact the windings, so there will be slight sparks during the adjustment process. It is suitable for use in environments with good ventilation.

Company Profile

Application Area

The Yibaling TDGC2J single phase contact voltage regulator is a classic manual voltage regulation device. Its core value lies in providing a simple and reliable physical solution for a specific scenario - the need for flexible, intuitive, and cost-effective voltage regulation.
In the electrical and electronic laboratory, it is not only an intuitive teaching aid for demonstrating the principles of electromagnetic induction and voltage regulation, but also a practice power supply for students to adjust circuit parameters and test component withstand voltages.
In the maintenance workshop, it serves as a variable test power supply, used to simulate voltage fluctuations, conduct aging tests on small batches of products, or provide a starting voltage from zero for unknown equipment to avoid damage caused by voltage mismatch.
In small-scale lighting, experimental heating, or small motor testing, this product offers the most direct means of power control.
The advantages and limitations of the TDGC2J single phase contact voltage regulator are equally distinct, directly stemming from its purely mechanical structure:
Advantages: The structure is extremely simple (ring-shaped winding, carbon brushes, scale), which means low cost, durable, strong overload capacity (able to withstand several times the instantaneous impact), and no need for an external control power supply, ready to use immediately.
Limitations: It completely relies on manual adjustment and monitoring by humans, unable to automatically stabilize voltage; the carbon brushes are mechanical wear parts, requiring regular inspection and replacement; there may be minor sparks during adjustment, and the response speed is slow.

FAQ

Q: What are the differences between the TDGC2J single phase contact voltage regulator and the automatic voltage stabilizer? Which one should I choose?
A: These are two products with completely different principles and applications:
TDGC2J single phase contact voltage regulator: The core is manual, adjustable. It is like a manual faucet. You need to turn the knob to set the desired output voltage (for example, from 0V to 250V), but it will not automatically maintain this voltage. If the input voltage changes, the output will also change, and you need to manually adjust it again. It is mainly used in experiments, tests, maintenance and other occasions where you need to actively change the voltage.
Automatic voltage stabilizer: The core is automatic, stable. It is like an automatic constant-pressure water pump. As long as the input voltage fluctuates within a certain range, it can automatically and quickly stabilize the output voltage at the rated value (such as 220V), without the need for manual intervention. It is mainly used to provide stable power supply for equipment.

Q: What is the maximum power of electrical appliances that the TDGC2J single phase contact voltage regulator can handle?
A: The maximum power that the TDGC2J single phase contact voltage regulator can handle for the connected electrical appliances is 60KVA (for larger power, our Yibaling factory also supports customization, please contact the customer service: Lassie). When using it, the total power of all connected loads must not exceed this rated value.
Special attention: For inductive loads such as motors and transformers, their starting current may be several times the rated value. When choosing the capacity, leave sufficient margin (it is recommended to select the capacity of the voltage regulator based on 2-3 times the rated power of the load).
