A 5 KVA Single Phase Air Cooled Servo Stabilizer by Shakti Servo is an essential electrical device designed to regulate voltage and protect appliances from electrical fluctuations. It is widely used in homes, small offices, clinics, and retail shops where a single-phase power connection is available and a load up to 5000 VA is required.
This type of stabilizer uses servo motor technology and an air-cooled mechanism to ensure smooth voltage correction and efficient thermal management. Understanding its functionality, applications, and features can help you choose the right stabilizer for your needs.
What Does 5 KVA Single Phase Air Cooled Servo Stabilizer Mean?
The term 5 KVA refers to the maximum load the stabilizer can handle, which is 5000 volt-amperes. In residential and small commercial setups, this is sufficient to manage multiple appliances running simultaneously. For instance, the Shakti Servo 5 KVA stabilizer can support a refrigerator, LED TV, air conditioner, washing machine, and a computer all at the same time.
kVA (kilovolt-amperes) is a unit of apparent power and differs from kilowatts (kW), which is actual power. In most cases, for a power factor of around 0.8, a 5 KVA stabilizer supports around 4kW of real load.
What Is a 5 KVA Single Phase Air Cooled Servo Stabilizer Connection?
A single-phase connection supplies power through two wires – one live and one neutral. It is the standard electrical supply for homes and small offices in India and many other countries. Single-phase stabilizers by Shakti Servo are designed specifically to operate with this supply type.
Working Principle of Shakti Servo Stabilizers
Unlike traditional stabilizers that operate using relays, a Shakti Servo stabilizer uses a servo motor to maintain the output voltage. The core components include:
- Buck-boost transformer
- Servo motor
- Control circuit
- Carbon brushes or moving contacts
When the input voltage fluctuates, the controller activates the servo motor, which adjusts the voltage through the transformer. The correction is smooth and continuous, making it highly reliable for sensitive devices.
Air Cooled Mechanism Explained
In a 5 KVA Single Phase Air Cooled Servo Stabilizer like those from Shakti Servo, heat generated during operation is dissipated naturally through air ventilation. There are no cooling fans or oil chambers. This design reduces maintenance and avoids noise, making it suitable for quiet environments like bedrooms, cabins, or clinics.
Compared to oil-cooled stabilizers, air-cooled versions are:
- Lighter in weight
- More compact
- Quieter in operation
- Better suited for indoor use
Input and Output Voltage Range
A standard Shakti Servo 5 KVA Single Phase Air Cooled Servo Stabilizer works within a wide input voltage range, typically from 140V to 270V or wider. The output voltage is kept constant, usually around 220V ± 1%, which is ideal for Indian appliances.
This consistent output voltage ensures that connected devices operate safely, without stress or overload.
Applications of 5kVA Single Phase Stabilizers
These stabilizers are used in various settings, including:
Residential Use
- Refrigerators
- LED/Smart TVs
- Washing machines
- Inverters and batteries
- Air conditioners up to 1.5 tons
- Computers and modems
Small Office & Commercial Use
- Desktop computers
- Printers and scanners
- Routers and CCTV systems
- Medical equipment (ECG, ultrasound, etc.)
- POS terminals and billing machines
Clinics and Labs
Many clinics use sensitive diagnostic tools that require stable voltage. A Shakti Servo 5 KVA Single Phase Air Cooled Servo Stabilizer provides reliable protection for such instruments, ensuring uninterrupted performance and safety.
Protection Features
Modern Shakti Servo 5 KVA stabilizers come with built-in safety mechanisms:
- Overload protection – Prevents damage when the load exceeds capacity
- Short circuit protection – Automatically disconnects during faults
- High/low voltage cut-off – Shuts down if voltage goes beyond safe levels
- Time delay function – Allows voltage to stabilize before reconnecting after a power failure
These features ensure the safety of both the stabilizer and the connected appliances.
Advantages of Using a Shakti Servo 5 KVA Servo Stabilizer
- Precise voltage control using a servo motor
- Smooth operation without sudden switching
- Low maintenance due to air-cooled design
- Silent performance without fan noise
- Energy-efficient and long-lasting
Installation Considerations
Before installing, ensure:
- The total connected load doesn’t exceed 5kVA
- The stabilizer is placed in a well-ventilated, dry area
- Wiring is done using proper gauges and earthing is secure
- A circuit breaker is installed before the stabilizer for added safety
Shakti Servo stabilizers can be wall-mounted or floor-installed, depending on the model design.
Conclusion
A 5 KVA Single Phase Air Cooled Servo Stabilizer by Shakti Servo is a technically sound solution for voltage regulation in residential and small commercial environments. It uses servo motor technology for precision and an air-cooled system for low-noise, efficient performance.
Understanding the capacity, internal working, and protection features of a 5 KVA Single Phase Air Cooled Servo Stabilizer makes it easier to select the right model for your needs. Whether it’s for a home setup or a small business, this Shakti Servo stabilizer ensures consistent power delivery and long-term safety of your electrical equipment.
