DROK Volt-Amp Meter AC Voltmeter Ammeter 0.39in LED Dual-Read 60–500V / 0–200A with CT, Panel Mount

DROK Volt Amp Meter is a compact two-in-one digital panel instrument that measures AC voltage (60–500V) and current (0–200A) simultaneously using the included current transformer.

This slim 0.39-inch LED panel meter displays voltage in red and current in green so you can monitor both values at a glance. The unit draws its operating power from the measured circuit, includes a flexible current transformer for easy placement, and offers a built-in trimmer for straightforward field calibration. A protective back cover and simplified wiring make it suitable for electrical panels, generators, and industrial equipment where space and clarity matter.

How accurate and wide-ranging are the voltage and current readings?

The DROK meter covers a broad AC voltage span and high-current applications with a dedicated CT for reliable sensing. While not a laboratory standard instrument, it provides clear, practical readings for everyday electrical monitoring tasks.

• Voltage range: AC 60–500V, displayed in red for rapid identification.
• Current range: 0–200A when used with the supplied current transformer, shown in green.
• Dual readout: both values visible at the same time on a single panel.

How do I install and power the gauge safely?

Installation is straightforward: the meter is powered directly from the circuit it measures, so no separate power supply is required. The supplied flexible CT simplifies current sensing and allows placement around a conductor without disconnecting it.

• Two-wire setup: connect voltage sampling to the measured AC line and neutral according to the wiring guide.
• CT clamp: place around a single conductor for current measurement—no additional CT purchase needed.
• Enclosed rear cover helps protect internal connections after mounting in a panel cutout.

Can I adjust or recalibrate the display if readings drift?

Yes—the meter includes a built-in trimmer potentiometer so you can fine-tune readings on site without special tools. This makes periodic checks and minor calibrations quick and user-friendly for technicians and installers.

• Front-accessible trimmer: adjust readings to match a reference instrument if needed.
• Simple procedure: small turns of the potentiometer change display values incrementally.
• Document adjustments: keep a record of calibration settings for consistent maintenance.

What environments and applications suit this panel meter best?

The DROK volt-amp display is designed for control panels, generators, UPS cabinets, and industrial equipment where simultaneous voltage and current visibility saves time. Its compact bezel and clear color-coded LEDs help technicians quickly assess electrical conditions in demanding workspaces.

• Ideal for electrical panels, motor control centers, and distribution boards.
• Useful for troubleshooting generators, inverters, and HVAC systems.
• Portable enough for retrofits and new-build panel installations.

Who is this for: technicians, electricians, and DIY-savvy installers who need a compact, two-in-one meter to monitor AC voltage and current in real time. It's a practical choice for facilities maintenance teams, small industrial shops, and hobbyists who require a clear, color-coded display and an included current transformer for flexible placement. Avoid using it where precision lab-grade measurements are required; instead, use it for practical monitoring, diagnostics, and routine panel monitoring tasks.
