Rail Mounting 220V 380V 100A Dual Display Digital Voltmeter and Ammeter

Product overview

Core functionalities

Applicable scenarios

Unique advantages

  • Dual Parameter Monitoring: Simultaneously measures and displays voltage (220V/380V) and current (up to 100A DC) via a clear digital interface, enabling real-time electrical system diagnostics.
  • Rail-Mounted Design: Engineered for secure installation on industrial panels or control panels, ensuring stability and easy integration into existing electrical setups.

Key features

  • 1. Durable Material Technology for Reliable Performance

    • With a rugged plastic housing reinforced by a metal mounting bracket, you can ensure long-term stability and cost-effectiveness compared to all-metal designs*. The plastic body reduces weight while the metal bracket guarantees secure installation in industrial environments.

  • 2. Dual LED Display for Simultaneous Monitoring

    • With dual white-backlit digital displays for real-time voltage (V) and current (A) readings, you can track electrical parameters at a glance, eliminating the need for multiple instruments like single-display meters*.

  • 3. High-Capacity Performance for Heavy-Duty Applications

    • With a max DC current capacity of 100A, you can handle demanding industrial loads, outperforming standard models limited to 50A or less*. This ensures reliable monitoring in high-power systems like motors or industrial equipment.

  • 4. Compact Design for Space-Constrained Installations

    • With a slim, rail-mountable design, you can install the meter in tight spaces such as control panels or electrical cabinets, ideal for commercial or industrial settings where space is limited*.

  • 5. Certified Safety for Peace of Mind

    • With CE/UL certification compliance, you can ensure adherence to global safety standards, offering superior reliability compared to uncertified alternatives*.
