User Instructions

Place the machine in a dry and ventilated place indoors, plug in the power plug or connect the wires according to the machine's logo. After checking that

everything is correct, turn on the machine's power switch, the machine works, and observe the output voltage meter indication. It should correctly indicate

220V, then turn on the electrical equipment used, the machine can automatically adjust the voltage and supply power normally. When the input voltage or

load changes, the servo motor in the machine will automatically rotate and adjust the output voltage. The rotation sound emitted is a normal phenomenon.

After use, turn off the power switch of the electrical equipment first, and then turn off the power switch of the voltage stabilizer. Please do not use the power

switch of the voltage stabilizer as the switch of all electrical appliances. This voltage stabilizer uses a fuse or automatic air switch as an overload or short

circuit protection. Before turning on the machine, check whether it is intact. This voltage stabilizer should not be used for a long time under overload

conditions. The time limit regulations for different overloads are shown in the table below.

Application Scope

SBW

Series Three-phase Compensated AC Power Stabilizer

SBW, SBW-F series compensated AC power voltage stabilizers (hereinafter referred to as voltage stabilizers) are

actual situation of the power grid. When the external power supply network fluctuates, it can automatically

maintain the stability of the output voltage.

Compared with other types of voltage stabilizers, this series of products has large capacity, high efficiency, no

waveform distortion, stable voltage regulation, strong control function, complete variety, wide application load,

ability to withstand instantaneous overload, long-term continuous work, manual/automatic switching at will, and

according to different use requirements, it has the options of AC/voltage-stabilized output, overvoltage,

undervoltage, overcurrent, phase sequence, mechanical failure and other automatic protection devices, as well

as small size, light weight, easy to use and install, and reliable operation.

This series of products can be widely used in large-scale electromechanical equipment, metal processing

equipment, production lines, engineering equipment, elevators and medical machinery, computer rooms,

computer control equipment, embroidery and textile equipment, air conditioners, radio and television, hotels,

household appliances and lighting in the fields of industry, agriculture, transportation, post and

telecommunications, military, railways, scientific research and culture, and all places that require voltage

stabilization.

Normal Working Conditions

1. Ambient temperature range: -15℃~+45℃;

2. Altitude not exceeding 1000m;

3. Relative humidity ≤90%;

4. The installation site should be free of gases, steam, chemical deposits, dust, dirt and other explosive

and corrosive media that seriously affect the insulation of the voltage stabilizer;

5. The installation site should be free of severe vibration or bumps;

6. Any special use conditions that do not meet the above requirements should be determined by the user and

our company through consultation.

Structural Features

The voltage stabilizer consists of a compensation transformer, a voltage regulator, a transmission mechanism, a

brush contact system, a box and a control system. The surface of the cylindrical winding of the voltage regulating

transformer is polished, the insulation is removed, and it is a smooth conductor surface to facilitate good contact

of the brush. The transmission mechanism consists of a servo motor, a sprocket and a chain.

Product features:

1. When the input power supply is missing, the voltage stabilizer can automatically detect and cut off the output.

2. The use of \"mains power direct technology\" reduces the number and capacity of AC contactors and

improves the reliability of the operation of the voltage stabilizer.

3. It has output voltage, over-voltage and under-voltage protection and alarm functions: in the voltage

stabilization state, when the input voltage exceeds the upper limit of the voltage stabilizer input (456V)

and reaches a certain value or other reasons cause the output voltage of the voltage stabilizer to be

higher than (426±8V), the output is cut off and an alarm is sounded. When the output voltage decreases,

it automatically returns to normal.

4. It has a call recovery function: when the power supply is restored after the power grid is out of power,

the voltage stabilizer has two optional functions: automatic power recovery and manual start.

5. It has a power-on delay function: in the voltage-stabilizing state, turn on the start button, and when the voltage

stabilizer adjusts itself to a stable value (a few seconds), KM3 will be energized and there will be voltage output.

HYIC3

Series of Intelligent Integrated Power Capacitor Compensation Devices

Application Scope

The HYIC3 series intelligent integrated power capacitor compensation device is based on two or more sets (

type) or one or more sets (Y type) of low-voltage power capacitors. It integrates advanced technologies such as

modern measurement and control, power electronics, network communications, and automated control. It

replaces traditional complete reactive power compensation devices, which consist of separate components

such as controllers, fuses, combination switches or mechanical contactors, thermal relays, low-voltage

capacitors, and indicator lights connected by wires within a cabinet.

This low-voltage reactive power compensation device features flexible compensation methods, excellent

compensation results, a compact size, low power consumption, easy installation and maintenance, a long

service life, strong protection features, and high reliability. It also offers true zero-crossing switching, meeting

users' actual needs and meeting the higher requirements of modern power grids for reactive power

compensation equipment.

Implementation standard: GB/T 15576 \"Low-voltage Complete Reactive Power Compensation Device.\"

Main Technical Parameters

Environmental Conditions:

Transport and Storage Temperature: -40°C to 70°C

Ultimate Operating Temperature: -25°C to 60°C (-40°C to 60°C available for custom products)

Relative Humidity: 20% to 90%

Altitude: ≤ 2000m (≤ 5000m for custom products)

Other Requirements: The installation site must be free of gases or conductive media that may corrode metal or

damage insulation, contain no explosive media, be free of strong vibration and shock, and

be free of severe mold.

Operating Voltage: AC 400V

Voltage Tolerance: ±30%

Operating Frequency: 50 ± 1.5Hz

Voltage Harmonics: Total Voltage Distortion Rate ≤ 5%

Network Quantity: ≤ 48 units per group

Structural Characteristics

1 Modular Structure

The intelligent capacitor features a modular design, compact size, simple wiring, and easy maintenance.

Capacity expansion only requires adding more modules.

2 Zero-Cross Switching

Core components enable “zero-cross switching,” achieving zero-voltage connection and zero-current

disconnection, reducing power loss with no inrush current, overvoltage, or arcing.

3 Protection Functions

Equipped with overvoltage, undervoltage, power loss, short-circuit, and over-temperature protection to extend

service life. Temperature protection automatically shuts down the unit when internal temperature exceeds safe

limits.

4 Control Technology

Switching is based on power factor and reactive power, using prediction and delayed multi-point sampling to

ensure stable, oscillation-free compensation, with sufficient reactive power under heavy load.

5 Intelligent Networking

Supports independent or networked operation. Faulty units automatically exit without affecting the system. Using

RS-485 communication, capacitors form an automatic network with adaptive master-slave switching for stable

operation.
