With a DC 4.5-30V range, the Mini Digital Voltmeter 2-Wire 0.36" Red LED tracks real-time voltage on batteries or power circuits. High-visibility LEDs provide data for UPS and IPS monitoring. Two-wire connectivity simplifies integration into existing DC systems.
Key Features
- Self-Powered Operation: Draws less than 20mA directly from the measured source. No external power supply is needed for the unit.
- Reverse Polarity Protection: Integrated safety circuit prevents damage during incorrect wiring. The module won't burn out if leads touch the wrong terminals.
- 0.36-Inch LED Readout: Clear 3-bit red display for low-light visibility. Makes reading voltage easy inside dark IPS battery cabinets.
- 200ms Refresh Rate: Updates five times per second to track rapid fluctuations. Captures sudden voltage drops during heavy load shedding.
- 15cm Connection Leads: Pre-attached wires facilitate quick installation in tight enclosures. Reach is sufficient for standard panel mounting.
Frequently Asked Questions
How to connect 2 wire digital voltmeter?
Connect the red lead to the positive terminal and black to negative. The unit powers itself directly from the DC source it measures.
Can I use this voltmeter for 12V battery?
Yes, the DC 4.5-30V range covers standard 12V lead-acid and lithium batteries. It tracks state-of-charge during discharge cycles.
