Dual Display Screen Voltage Current Protector
Pugao Dual Display Screen Voltage Current Protector supplier offers a smart protection solution combining real-time voltage and current monitoring with adjustable electrical protection. Dual LED displays provide instant V+A visibility for residential, solar, commercial, and industrial systems.
A power problem is often discovered only after equipment stops working. Without knowing the actual voltage and current condition, users may spend time checking wiring, replacing components, or using external meters to identify the cause. Pugao supplies the Dual Display Screen Voltage Current Protector to help users see electrical conditions directly while adding automatic protection against abnormal voltage and current situations.
Unlike traditional protection devices that mainly disconnect circuits during faults, this device works as a combination of a digital electrical monitor and a protection controller. The upper LED screen displays voltage values, while the lower screen shows current values, allowing operators to understand the real operating status of connected equipment immediately.
When Electrical Problems Happen, Visibility Matters First
Hidden electrical conditions create unnecessary troubleshooting
Many electrical failures are difficult to diagnose because the actual operating condition cannot be seen.
Common situations include:
Appliances damaged after unexpected voltage fluctuation.
Motors stopping because of insufficient voltage.
Equipment overload caused by excessive current demand.
Unstable grid conditions affecting normal operation.
A standard circuit breaker can protect against certain electrical faults, but it does not continuously display the voltage and current values before or during operation.
The Dual Display Screen Voltage Current Protector solves this visibility problem by allowing users to monitor electrical parameters directly from the distribution panel.
Protection combined with real-time measurement
The value of this device is not only automatic disconnection. It also provides users with real-time information before maintenance decisions are made.
The integrated design combines:
Voltage measurement.
Current measurement.
Over-voltage protection.
Under-voltage protection.
Over-current protection.
Automatic recovery function.
This two-in-one approach reduces the need for additional measuring instruments in many daily inspection situations.

Even when installed inside distribution boxes or electrical cabinets with limited lighting, the bright LED display allows users to check electrical information without opening additional testing equipment.
Visual monitoring helps identify power quality issues
In unstable power environments, users often cannot determine whether a problem comes from voltage fluctuation or excessive current loading.
With real-time monitoring, operators can:
Observe voltage changes directly.
Check whether current exceeds expected levels.
Confirm abnormal conditions before restarting equipment.
Improve maintenance efficiency.
For solar installations, remote areas, and industrial equipment, visible electrical data provides practical value during daily operation.
Protection Functions Respond to Different Electrical Abnormalities
Over-voltage protection
Sudden voltage increases may damage connected electrical equipment.
Possible causes include:
Abnormal grid conditions.
Wiring problems.
Power restoration fluctuations.
When voltage exceeds the preset protection value, the device disconnects output power to help protect connected loads.
Under-voltage protection
Low voltage can also create operational problems, especially for equipment with motors or sensitive components.
When voltage falls below the configured value:
Output power is disconnected.
The device indicates the abnormal condition.
Automatic recovery can occur after voltage returns to normal.
This function helps reduce risks caused by prolonged operation under insufficient voltage.
Over-current protection
Excessive current may occur when connected loads exceed expected operating conditions.
The device allows users to set current protection values and provides:
Real-time current monitoring.
Automatic trip protection.
Fault indication through LED signals.
Automatic recovery after conditions return to normal
After the electrical condition becomes stable, the device can automatically restore power after the preset delay period.
The recovery function helps reduce unnecessary manual operation while preventing immediate energizing during unstable recovery conditions.
Designed for Different Power Environments
Residential electrical protection
Home users usually notice electrical problems only after appliances fail or lighting becomes unstable.
Typical applications:
Home distribution boxes.
Appliance protection circuits.
Electrical renovation projects.
The Dual Display Screen Voltage Current Protector allows homeowners and electricians to check actual power conditions instead of relying only on fault symptoms.
Solar and renewable energy systems
Solar installations may experience changing power conditions depending on generation, connection, and local grid stability.
Typical applications:
Solar distribution systems.
Photovoltaic supporting equipment.
Renewable energy electrical cabinets.
Real-time voltage and current information helps operators understand system conditions and identify abnormal electrical situations faster.
Factory equipment and motor protection
Industrial equipment often requires stable electrical input to maintain operation.
Typical applications:
Motor-driven machines.
Factory control panels.
Equipment distribution cabinets.
Monitoring current values helps users recognize abnormal load conditions, while voltage protection reduces risks caused by unstable supply.
Rural and remote power networks
Some locations experience more frequent voltage variation because of grid distance or power demand changes.

Simple Operation for Parameter Adjustment
Front-panel buttons simplify configuration
The device is designed for direct user adjustment without complicated external tools.
Main controls include:
SET button: Adjusts protection parameters such as over-current, high voltage, low voltage, and delay settings.
UP button: Increases selected values.
DOWN button: Decreases selected values.
Manual ON/OFF button: Controls output status manually.
Users can configure:
Over-voltage protection threshold.
Under-voltage protection threshold.
Over-current protection threshold.

LED indicators provide clear fault information
The indicator system helps users recognize different operating conditions:
A> indicator: Over-current fault.
V> indicator: High-voltage fault.
V< indicator: Low-voltage fault.
OUT indicator: Output status.
This visual feedback reduces confusion during installation and maintenance.
