SVC(TND) Series High Precision Full-Auto AC Voltage Stabilizer / Voltage Regulator
SVC(TND) series single-phase high precision full-auto AC voltage regulator/voltage stabilizer adopts a linear integrated circuit servo motor control system. It drives the contact voltage regulator to regulate automatically by controlling the servo motor. It features small waveform distortion, a high power factor, and remains unaffected by frequency variations of the power supply. It is used in most situations where voltage fluctuation requirements are critical.

Each voltage stabilizer is packed in a wooden case. Inside, we first use a plastic bag, and then place 4 pieces of 3.5mm thick foam to protect the door meter and switch.
Generally we ship to Ningbo or Shanghai sea port. We can provide FOB, CIF, or CNF price.
Voltage regulator / Voltage stabilizer quality control is highly important for every customer. We control quality from every single spare part, especially the coil power and the PCB board. See the details in the technical image below.
We provide a quality guarantee period of 2 years for our voltage regulators/stabilizers. With proper loading and following our technician's suggestions, we offer a 5-year guarantee period (during the 5-year period, if the input voltage fluctuates frequently, only the carbon brush needs to be changed). Every voltage stabilizer undergoes testing of parts before assembly, and finished output and loading testing after assembly. Dynamic testing is conducted after the assembly is completed, and we test again after packaging. Below is our testing equipment:
If the voltage regulator/stabilizer encounters any issues or if you have a special stabilizer design inquiry, we will reply within 24 hours as our sales team consists of technicians.
For three-phase voltage regulators/stabilizers, we design configurations where the output requires 220V (general is 380V), including surge protection and overloading protection, with a full power loading design. Silicon area and winding wire sizes are specially designed.
We accept OEM or ODM orders. Customers can provide their logo, company name, and packaging box design. If you do not have a design, we can design it for you. We print the logo and company name on the voltage stabilizer panel and small power carbon boxes.
We accept sample orders to test our quality. Before making the sample, we confirm all specifications. The sample is first tested by our sales technicians, and after testing is finished, it is sent to the customer for quality check. For small power samples, we provide the sample for free with the customer paying the shipping cost.
Engineers and managers in our factory possess 15 years of stabilizer production experience. We ensure quality standards, competitive rates, and reliable lifecycle after-sales support.
