5-Pack Digital DC Panel Voltmeters 5V–120V — Ready-to-install, hassle-free monitoring
Whether you’re juggling multiple projects, working in an automotive workshop, or simply need reliable spares on hand, this 5-pack of digital panel voltmeters is the perfect solution. Designed for continuous DC voltage monitoring, these units feature a simple 2-wire installation that requires no separate power source.
Note: The maximum supported voltage is 132V DC. Do not exceed this limit to ensure the device remains protected.
Why choose this set? (Key Advantages):
- 5-Pack Value — Significant cost savings compared to individual units; ideal for workshops, service centres, or simultaneous projects.
- 2-Wire Setup, No External Power Needed — The voltmeter draws power directly from the voltage being measured, saving you time and installation space.
- 0.56″ Green LED Display, 3-Digit — Provides a clear, easy-to-read display day or night, perfect for dim workshops or vehicle dashboards.
- 5V–120V DC Range — Fully compatible with 12V, 24V, and 48V systems, as well as high-voltage solar installations without needing adjustments.
- 300ms Refresh Rate — Near-instantaneous monitoring, allowing you to track voltage fluctuations in real-time.
- Standard 46×27 mm Cutout — Designed to fit perfectly into standard panel cutouts, plastic housings, or metal enclosures.
- Low Power Consumption (<18mA) — Virtually invisible to the circuit being monitored, making it safe for use with small batteries or accumulators.
Performance and Specifications
Each voltmeter in this set measures DC voltage with an accuracy of ±1% — providing the precision needed for automotive diagnostics, battery health checks, or solar panel monitoring. With an input impedance of over 100KΩ, the device won’t interfere with sensitive circuits. The operating temperature range of -20°C to +65°C ensures reliable performance, whether you’re dealing with winter conditions in a vehicle or summer heat on an outdoor inverter.

Frequently Asked Questions
Does this work on a 48V solar system?
Yes. The 5V–120V DC range fully covers 12V, 24V, and 48V systems. Readings remain accurate within ±1%, regardless of the panel’s charge level.
Do I need a separate power supply?
No. The voltmeter is powered directly by the voltage it is measuring. Simply connect the two wires and you’re ready to go — no external batteries or transformers required.
What size cutout do I need for the panel?
The standard cutout size is 46 × 27 mm. This can be easily achieved in plastic, metal, or wood using a drill and file or a panel cutter.
Will it withstand cold weather if mounted in a car?
Yes. It is rated for operation between -20°C and +65°C, making it perfectly suitable for harsh winters and the high temperatures found in a car dashboard during summer.
Why buy a 5-pack if I only need one right now?
The price per unit is significantly lower when purchased as a set. Plus, you’ll have spares ready for future projects or quick replacements without needing to wait for another delivery.
