0.56' Volt Meter Green 4-30VDC

A compact 0.56-inch green LED panel voltmeter for 4–30 V DC systems — self-powered from the measured supply, requiring no separate power connection. With a 48 × 29 × 22 mm housing designed for panel mounting, it's the cleanest way to add a permanent voltage readout to any power supply, battery system, or control panel.

🔹 Key Applications

• Battery voltage monitoring in 12 V and 24 V systems
• Panel-mounted voltage display in power supplies
• Solar system battery bank voltage readout
• Workshop bench supply voltage indicator
• Automotive battery and alternator voltage display
• EV and e-bike battery state-of-charge indicator

🔹 Why Choose This Module?

• Self-powered (4–30 V) — no separate supply wiring
• Green LED display — high visibility in low-light environments
• Panel-mount ready — standard cutout dimensions

🔹 What's Included

1 × 0.56" Green LED Panel Voltmeter (4–30 V)

🔹 Pro Tip

💡 Panel cutout size: 45 × 26 mm. Use the mounting clips to secure from behind. For battery state-of-charge displays, mark your voltage thresholds (e.g. 12.7 V = full, 11.8 V = 50%, 11.0 V = empty) on the panel next to the display for quick visual reference.

⚠️ Note: Always ensure proper heat dissipation and correct voltage configuration before powering connected devices.
