DJW, SJW high-precision fully automatic AC voltage stabilizer
This voltage regulator is based on the SVC high-precision fully automatic voltage regulator and is carefully designed with additional protection circuits according to practical needs. It consists of an autotransformer, control circuit, and servo system, and has the characteristics of high efficiency, wide voltage regulation range, and no waveform distortion. It is widely used in computer rooms, home appliances, audio systems, factories, color printing production lines, industrial automation, and other occasions. TSD is a wall mounted installation with a working principle similar to SVC, making it an ideal power supply for home appliances, medical, and office equipment.
Structural features: The DJW, SJW (SVC, TND) series high-precision fully automatic single and three-phase AC stabilized power supply is a new generation of multifunctional stabilized power supply developed and produced by our company by introducing advanced foreign technology and leveraging the strengths of Bozhongjia. Its performance indicators fully comply with the ZBK42002-87 standard. A regulated power supply is composed of a contact voltage regulator, an automatic control circuit, and a servo motor. When the voltage of the power grid is unstable or the load changes, the automatic control circuit takes samples and compares them. Amplify and control the servo motor to drive the rotating arm, and the electric brush rotates in the desired direction to adjust the output voltage to the rated value, thus achieving the purpose of voltage stabilization. This regulated power supply has the characteristics of beautiful appearance, small size, light weight, low self power consumption, complete protection functions, stable and reliable performance, long-term operation, and low output waveform distortion. To ensure product quality, the key component of the regulating iron core is made of imported silicon steel sheets, which are self-designed and wound. The key components of the control circuit are made of imported parts, and the electric brushes are made of new materials with excellent characteristics.
Usage scenario: Voltage stabilized power supplies are widely used in areas with large fluctuations in grid voltage or seasonal changes in grid voltage. They can provide high-quality power to household appliances such as computers, testing equipment, lighting systems, communication systems, CNC machine tools, medical equipment, industrial automation equipment, copiers and televisions, electrophoresis boxes, air conditioners, etc.
Structural features: The anti electric shock protection method is Class I. Single phase: 0.5KVA-5KVA; Three phase: 1.5KVA-4.5KVA; The structure is a desktop placement structure. Single phase: 10KVA-30KVA; Three phase: 6KVA-30KVA. The structure is a cabinet style placement structure. The display instrument is fixed on the upper panel, and the lower single door is maintained with a visible hinge. The surface is coated with gray plastic powder by electrostatic spraying.
SJW series high-precision three-phase AC stabilized power supply:
The SJW series three-phase adjustable fully automatic AC voltage regulator is composed of three sets of DJW single-phase voltage regulators combined by star connection. It has functions such as overvoltage protection, overvoltage protection, delayed output, fault protection, and phase loss protection, and is suitable for stabilizing power supply and protection of any three-phase equipment, as well as comprehensive voltage stabilization protection for small business electricity.
Scope of application: Suitable for industrial instruments and equipment, medical equipment, computer networks, elevators, and small businesses to provide comprehensive stable power supply.
