What Is an AC Voltage Regulator?

An AC voltage regulator is a power management device designed to deliver a consistent output voltage, even when the input power supply is unstable. This is essential for protecting sensitive equipment from damage due to voltage fluctuations. The TKB Series (15KVA–30KVA) by SUNWAY is built for high-demand environments, including large homes, commercial setups, workshops, and offices, offering automatic voltage correction with exceptional reliability and efficiency.

Key Features:

• High Efficiency (>95%): Minimizes energy loss while protecting your equipment
• Relay Type Control: Fast response to voltage fluctuations without mechanical wear
• Wide Input Voltage Range: Options from 45V–260V up to 140V–260V, customizable as needed
• Digital Monitoring: Clear display of both input and output voltages
• Multiple Protections: Built-in safeguards for overvoltage, undervoltage, overtemperature, overload, and delayed start-up

TKB vs. Other Voltage Regulator Types

Unlike servo motor regulators, which use motor-driven mechanisms that may wear out over time, the TKB relay-type AVR is faster, quieter, and requires less maintenance. While some regulators are limited to narrow voltage correction ranges, the TKB series handles extreme input swings, making it suitable for unstable grids.

TKB Relay Type Advantage:

• No moving parts = longer service life
• Quicker response during voltage spikes
• More compact and lightweight compared to servo-based models
• Customizable protection settings and voltage ranges

Which Model Should You Choose?

Choosing the right TKB model depends on the total wattage of your load and whether it’s resistive (lights, heaters) or inductive (ACs, motors).

• TKB-15KVA: Ideal for high-end households or workshops with a few heavy appliances.
• TKB-20KVA: Suitable for small office setups, multiple air conditioners, or medical equipment.
• TKB-30KVA: Perfect for large houses, small factories, or commercial premises.

💡 Tip: Always choose a model rated at least 20–30% higher than your total load to handle startup surges safely.

الأسئلة الشائعة

Q1: Can the TKB voltage regulator support inductive loads like motors or welding machines?
A: Yes, the TKB series is designed to handle both resistive and inductive loads. For equipment with high startup current, consider selecting a unit with higher capacity (e.g., TKB-20KVA or TKB-30KVA).

Q2: Is it safe to install the voltage regulator outdoors?
A: These units are meant for indoor use. However, they can be installed in a covered outdoor area if protected from direct sunlight, rain, and dust.

Q3: How long is the delay function, and can it be adjusted?
A: The built-in delay function has two modes: Short Delay (6 seconds) and Long Delay (180 seconds). This protects appliances during power recovery. Some models allow toggling between the two.
