Modular digital 3-phase voltage indicator | 3P | 80-500VAC | DIN | DVI3P VEXEN

Technical Specifications:

Number of phases: 3 (L1, L2, L3)

Voltage: 80–500 VAC

Current: ≤10 mA

Frequency: 50–60 Hz

Measurement accuracy: ±2%

Power consumption: ≤2 VA

Display: LCD, separate for each phase

Mounting: DIN rail (35 mm)

Operating temperature: –30 °C to +70 °C

Protection class: IP20

Housing material: Non-flammable plastic

Features:

Real-time three-phase voltage measurement

LCD display with clear voltage indication for each phase

Visual monitoring without additional tools

Suitable for distribution panels or control boxes

Operates over a wide temperature range

Compact design saves panel space

Applications:

Electrical distribution panels (residential and industrial)

Industrial equipment control cabinets

Monitoring of automation and substation equipment

Power grid maintenance solutions

Distribution panels for solar power plants or generators

Temporary power supply (construction sites, pavilions)

Advantages:

Wide voltage measurement range (80–500V) – suitable for both low and higher voltage networks

LCD display – clear visual indication for each phase

Compact design – fits even in small panels

Low power consumption – ≤2VA

Easy installation – DIN rail mounting

Temperature resistance – operates from –30 °C to +70 °C

Disadvantages:

Monitoring only, no protection functions – does not take action when voltage deviates from the norm

No alarm – does not detect phase sequence or overvoltage

No data transmission – lacks RS485 or other communication protocols

Reliable, economical solution for those seeking a simple way to continuously visually monitor three-phase system voltage without additional alarms or automatic intervention. Ideal for electrical panel maintenance, especially when quick and clear system status assessment is important.
