The AC electronic voltage regulator features excellent design, stable performance, reliable quality, a wide input voltage range, and user-friendly operation, making it highly favored in both domestic and international markets, particularly in European countries. We welcome all users to utilize our products.

main performance ：

• 1. Wide voltage input range (90–130 V). 2. Overvoltage protection (>310 V: LED light activates). 3. Low-voltage protection (<90 V: LED light activates). 4. Overload protection alarm. 5. Overtemperature protection (80°C).

• short-circuit protection 。

LCD liquid crystal parameter display + LED light display: Input: Input voltage; Output: Output voltage; Power output: Operating power. The operating status is indicated by a green indicator light, while the fault status is indicated by a fault indicator light. If abnormal temperature, overload, short circuit, overvoltage, or undervoltage occurs, the corresponding indicator light will illuminate.

LED display description: The green indicator light indicates operational status; the red indicator light indicates TRB overload; the red indicator light indicates insufficient AC/UNDV voltage; the red indicator light indicates excessively high AC/OUV voltage.

Short-circuit protection: When a short circuit occurs at the output, the output is shut off and automatically returns to normal after the short-circuit is resolved.

High-temperature protection function: When the radiator temperature exceeds 80°C + 2°C, the output will automatically shut off; when the temperature drops below 60°C + 2°C, the output function returns to normal.

Smart Fan: The fan automatically starts when the radiator temperature exceeds 60°C and stops when it drops below 40°C.

overload protection ：

• Output overload. When the input voltage is 2190 V, the output current exceeds the rated value, causing the output voltage to drop. When the voltage falls to 180 V + 5 V, the output will automatically shut down and restart after 13 seconds.

2. Input overload. When the input voltage is 185V, the input current exceeds the rated input current, causing the output voltage to drop. The output will disconnect when the voltage falls to 180V + 5V and will restart after 13 seconds.

3. When the output current exceeds 200% of the rated current, the system will promptly activate protection, disconnect the output, and restart after 13 seconds.

4. When the output current exceeds 200% of the rated current, the system will promptly initiate protection.

Disconnect the output and restart after 13 seconds.

This feature is applicable when the input voltage ranges between 190V and 240V.

When the output current exceeds 150% of the rated output current, the output voltage decreases; when the voltage falls below 180V ± 5V, the input and output are in a direct-through state.

When the output current drops to 80% of the rated current, the system resets and stabilizes the voltage output.

Installation Instructions: During operation, this machine should be kept away from flammable and explosive materials, high temperatures, humidity, and other harsh environments. It must be placed in a well-ventilated, dry area free from direct sunlight.

The formula for calculating output power when the input voltage is less than 185V:

If the input voltage of the AC-88A model is 170V, the maximum output power is

P=170*3.65=620.5W
