Unitec 20kVA 3 Phase Servo Voltage Stabilizer for Industrial & Commercial Applications
Unstable electricity supply can have a significant impact on industrial machinery and commercial electrical equipment. Low voltage, high voltage, sudden power drops and voltage fluctuations can affect machine performance, increase electrical stress and potentially result in expensive equipment damage.
The Unitec 20kVA Three Phase Servo Voltage Stabilizer is designed to provide automatic voltage regulation for businesses and industrial facilities in Sri Lanka. With a wide input voltage range of 304V to 440V and a regulated output of 380V ±4%, this industrial voltage stabilizer helps provide a more consistent power supply to connected three phase equipment.
The unit uses a servo motor controlled voltage regulation system, allowing it to automatically correct incoming voltage variations and maintain the required output voltage.
It is suitable for installations supplied through CEB and LECO where voltage fluctuations can affect sensitive or high-value equipment.
Automatic Voltage Regulation with Servo Motor Control
The Unitec 20kVA stabilizer uses a servo motor controlled system to regulate the incoming three phase voltage.
As the input voltage changes, the servo mechanism adjusts the voltage automatically to maintain the required output.
This makes the stabilizer suitable for applications where stable voltage is important for consistent equipment operation.
Key benefits include:
- Automatic voltage correction
- Stable three phase output
- Reduced effects of voltage fluctuations
- Improved equipment operating conditions
- Protection against unstable supply voltage
- Suitable for continuous commercial and industrial use
Wide 304V–440V Input Voltage Range
The stabilizer accepts an incoming voltage range of:
304V – 440V AC
This allows it to compensate for significant variations in the incoming three phase supply while maintaining an output of:
380V ±4%
This makes the Unitec stabilizer particularly useful in areas where the incoming supply experiences low voltage or high voltage conditions.
Stable 380V Three Phase Output
Many industrial machines and commercial electrical systems require a consistent three phase supply.
The Unitec 20kVA stabilizer regulates the incoming power and provides:
380V AC ±4%
A stable voltage supply can help electrical equipment operate more consistently and reduce the electrical stress associated with significant voltage variations.
20kVA Capacity for Industrial Applications
With a rated capacity of 20kVA and rated current of 30A, this stabilizer is designed for a wide range of three phase commercial and industrial applications.
It can be considered for applications involving:
- Industrial machinery
- Manufacturing equipment
- CNC machines
- Pumps
- Compressors
- HVAC equipment
- Printing equipment
- Packaging machinery
- Workshop equipment
- Commercial electrical systems
The actual suitability of the stabilizer should be determined based on the connected equipment’s starting current, running load and overall electrical requirements.
Designed for Sri Lankan Power Conditions
Voltage instability can be a concern for businesses operating on the CEB and LECO electricity networks.
A voltage stabilizer can help businesses maintain a more consistent voltage supply when the incoming electricity experiences fluctuations.
The Unitec 20kVA industrial stabilizer is therefore suitable for businesses in Sri Lanka looking for a solution to low voltage, high voltage and power drop conditions affecting three phase equipment.
Analog Voltage & Current Monitoring
The stabilizer features analog meters on the front panel for convenient monitoring of the electrical supply.
The meters allow the operator to monitor:
- Three phase output voltage
- Current / Ampere
This provides a quick visual indication of the stabilizer’s operating condition without requiring separate measuring equipment.
90% Operating Efficiency
The Unitec 20kVA stabilizer has a specified efficiency of 90%, allowing it to regulate incoming voltage while maintaining efficient operation.
The combination of automatic voltage correction and 90% efficiency makes it suitable for commercial and industrial installations requiring regular voltage regulation.
4-Second Response Time
The stabilizer has a specified response time of approximately 4 seconds against a 10% input voltage fluctuation.
This allows the servo regulation system to respond automatically to changes in the incoming supply and adjust the output accordingly.
