Customized Multicolour 6-Digit 7-Segment LED Display Module for Auto Voltage Stabilizer Regulators
Product Overview
Introducing the Customized Multicolour 6-Digit 7-Segment LED Display Module—a voltage stabilizer-optimized solution engineered for auto voltage regulators, instrument panels, and power-related equipment. Designed to prioritize multi-colour status cues, clear voltage readouts, and easy integration, this 6-digit module excels at showing critical power metrics: input voltage (e.g., "245V"), output voltage (e.g., "220V"), or error codes (e.g., "E01" for overload).
Its 11.4mm (0.45-inch) digit height ensures readability from 1–3 meters (typical for voltage stabilizer installation areas like basements or utility rooms), while the 145×35×12mm module size fits standard regulator control panels—no bulky redesigns required. The white segments on a black surface enhance contrast with four selectable colours (blue/green/red/yellow), each serving a functional purpose (e.g., green for normal voltage, red for alerts) to help users instantly recognize power status.
With common cathode polarity, low power consumption, and RoHS compliance, this module delivers reliable performance for 24/7 voltage monitoring—ideal for both residential and industrial auto voltage stabilizers.

Key Features (Auto Voltage Stabilizer Regulator-Optimized)
1. Multicolour Functionality for Voltage Status Cues
Four Targeted Colours with Clear Roles:
Blue (460-465nm, 80-100mcd): Ideal for normal output voltage (e.g., "220V"/"110V")—bright enough for visibility, with a calm tone that signals stable power.
Green (569-573nm, 30-40mcd): Suits low-but-safe input voltage (e.g., "180V")—subtle yet distinguishable, indicating non-critical voltage fluctuations.
Red (630-635nm, 50-60mcd): Reserved for overvoltage/undervoltage alerts (e.g., "250V"/"150V") or errors—highly noticeable, immediately warning users of power risks.
Yellow (585-595nm, 50-60mcd): Used for transition states (e.g., "REG" for regulating) or moderate warnings (e.g., "235V" near overvoltage)—balances visibility and urgency.
Colour-Coded Intensity Matching: Each colour's luminous intensity is optimized for its role (e.g., higher brightness for red alerts, lower for green non-critical states), avoiding glare while ensuring status clarity.
2. 6-Digit Precision for Voltage Readouts
6-Digit Capacity: Supports full voltage ranges (e.g., "000.0V" for low-power devices to "300.0V" for industrial use) and error codes (e.g., "E0012" for detailed faults)—critical for auto voltage stabilizers that need to display input/output voltages simultaneously or diagnostic information.
11.4mm (0.45-Inch) Digit Height: Balances readability and panel fit—large enough to distinguish decimal points (e.g., "220.5V" for precise regulation) from a distance, small enough to avoid dominating the regulator's control panel.
3. Stable Performance for Power Monitoring
Voltage & Current Optimization: Forward voltage (1.8-3.2V) and current (5-10mA/LED) match the power supply of most auto voltage stabilizers—no need for custom converters, simplifying integration and reducing power waste.
Stable Operation in Power Fluctuations: Withstands voltage spikes or dips (common in stabilizer use) and temperature variations (-10°C to 60°C, typical for utility rooms)—maintains consistent brightness and colour accuracy, no flickering during voltage regulation cycles.
Long Lifespan (50,000+ Hours): High-quality LEDs and module construction match the 8–10 year service life of auto voltage stabilizers—eliminates frequent module replacements, reducing maintenance hassle for users.
4. Easy Integration & Compliance
Common Cathode Polarity: Works with standard stabilizer driver ICs (e.g., TM1638, HT1621, MAX7219)—simplifies circuit design for manufacturers and integrates seamlessly with stabilizer firmware (e.g., voltage sampling, colour-switching logic for status changes).
Easy Assembly: The module is pre-assembled for direct mounting on the stabilizer's PCB—saves manufacturing time, avoids manual segment wiring errors, and ensures consistent alignment.
RoHS Compliant: Free from lead, mercury, and harmful substances—safe for residential use and export to global markets (EU, North America, Asia), meeting power equipment safety standards.

Applications
This module is purpose-built for auto voltage stabilizers and power-related equipment, including:
Auto Voltage Stabilizer Regulators: Residential (input "150-250V", output "220V") and industrial (input "200-400V", output "380V") models, showing voltage levels and regulation status.
Power Instrument Panels: UPS (Uninterruptible Power Supply) displays (battery "12.5V", load "50%"), power inverters (input "12V", output "220V"), or surge protectors (voltage "230V").
Voltage Monitors: Portable power testers (socket voltage "225V"), laboratory power supplies (output "0-30V"), or smart home energy monitors (grid voltage "220.5V").
Why Choose This Module for Auto Voltage Stabilizers?
Instant Status Recognition: Multicolour cues let users identify voltage risks (red) or stability (blue) without reading digits—critical for non-technical users.
Precision Voltage Readouts: 6-digit capacity supports detailed voltage data, helping technicians troubleshoot regulation issues.
Stabilizer-Friendly Design: Optimized voltage/current and easy assembly fit standard stabilizer PCBs—saves manufacturers redesign time.
Long-Term Reliability: Lifespan matches stabilizers, reducing maintenance; RoHS compliance ensures global usability.
