Voltage Stabilizer, Model SBW-300

Description

Voltage Stabilizer

The Stabilizer is a high-power energy supply voltage stabilizer, 380V, 3-phase, 4-wire, Model SBW series with booster.

Ensures stability within 3-5%

What is a Stabilizer:
A Voltage Stabilizer is an electrical device designed to maintain a constant and steady voltage level, protecting against voltage sags (under-voltage) and surges (over-voltage). It adjusts the electrical current to an optimal level for sensitive equipment such as servers, telephone exchanges, medical devices, scientific instruments, industrial machinery, or any other equipment requiring stable power.

The Stabilizer is an essential component in electrical systems for regulating and maintaining stable voltage levels. Its operational principle involves monitoring and adjusting the voltage to ensure consistent output. This leads to more stable and safe operation of electrical systems, particularly in environments with multiple electrical devices or fluctuating power supply. For instance, in factories or laboratories where the 380-volt supply might fluctuate between 200 and 400 volts, unstable power can damage equipment or lead to insufficient power output. The Stabilizer corrects these fluctuations, ensuring a stable three-phase power supply. Utilizing a Voltage Stabilizer helps prevent damage to electrical equipment caused by voltage instability and extends their operational lifespan by maintaining an appropriate voltage level.

Voltage Stabilizers are available in various forms, ranging from domestic units to industrial-grade machines. Typically, they can handle power loads from 1,000 Watts to 5,000 Watts or more and operate within voltage ranges from 110 Volts to 240 Volts. Common types include Automatic Voltage Regulators (AVR) and Servo Motor Stabilizers, each differing in their voltage control and adjustment mechanisms. The selection of a Voltage Stabilizer depends on the specific application and requirements.

Benefits of a Stabilizer:
1. Ensures smooth power delivery.
2. Enables connected equipment to operate at peak performance with consistent electrical current.
3. Reduces the incidence of damage caused by electrical anomalies.
4. Extends the lifespan of equipment by maintaining optimal voltage.

F1 Regulated Output Value: Do not adjust beyond 410.
F2 Overvoltage Protection Value: Default is 430.
F3 Undervoltage Protection Value: Default is 320.
F4 Regulated Accuracy Value: Default is 8-10.
F5-F7: Do not adjust.
F8 is the Current Protection Value. This can be fine-tuned. In scenarios with very high instantaneous current draw by the customer’s equipment, this value can be slightly adjusted to ensure stability after the current stabilizes, based on the actual situation.
