• Sensitive electronic devices that require stable mains voltage
• Residential and small commercial electrical installations

Key specifications

• Automatic voltage regulation with 8% precision
• Designed for single-phase mains supply
• Compact enclosure suitable for wall or floor placement
• Continuous operation to correct over-voltage and under-voltage
• Intended for residential and small commercial load levels

How to use

Install the stabilizer according to local electrical codes, ensuring the device is connected to the mains supply before attaching loads. Place the unit on a flat, stable surface or mount it on an appropriate wall if space requires. Connect the electrical appliances to the stabilizer output and switch the unit on; it will monitor incoming voltage and automatically adjust output to maintain stable supply. Regularly inspect connections and keep ventilation openings unobstructed to ensure proper cooling during operation.

Usage recommendations

For reliable performance, position the stabilizer in a dry, well-ventilated area away from direct sunlight and heat sources. Verify that the total connected load remains within the device's intended capacity and avoid connecting inductive loads with high starting currents without consulting technical specifications. Periodic visual inspection and cleaning of dust from vents will help maintain operational stability.
