DROK Volt Amp Meter 2-in-1 Digital Panel Voltmeter Ammeter 60–500V 0–200A LED Dual-Color Display with CT and Trimmer

The DROK Volt Amp Meter is a compact 2-in-1 digital panel meter that displays AC voltage (60–500V) and current (0–200A) simultaneously using a built-in current transformer for easy, safe monitoring.

This slim 0.39-inch LED gauge combines a voltmeter and ammeter in one unit, showing voltage in red and current in green so you can read both values at a glance. It runs off the measured circuit (no separate power supply needed), includes a flexible current transformer (CT) for convenient placement, and offers a trimmer potentiometer for in-field calibration. The back cover and simple 2-wire connection make installation straightforward and safer for panel mounting.

How accurate and wide-ranging are the measurements?

The DROK meter covers a useful household and industrial AC range: 60–500V for voltage and 0–200A for current. The supplied CT lets you measure higher currents without bulky wiring through the meter body, and the built-in trimmer allows fine-tuning if your readout needs calibration.

• Voltage range: AC 60–500V
• Current range: 0–200A via included CT
• Calibrate easily using the built-in trimmer potentiometer
• Separate color-coded LEDs for immediate clarity

What does the display show and how easy is it to read?

This model uses a dual-color LED display: red numerals for voltage and green for current, so both values are visible simultaneously without switching modes. The 0.39-inch digits are compact but clear for panel use; contrast between the colors helps reduce reading errors in bright or dim environments.

• 0.39" LED digits: red for volts, green for amps
• Simultaneous voltage and current readout
• No mode toggling — immediate snapshot of the circuit's status
• Panel-mount friendly bezel and covered rear for safety

How do I install and power the meter?

Installation is designed for simplicity: the gauge is powered directly by the measured circuit, so no extra power wire is necessary. The package includes a current transformer that clamps around the conductor, enabling flexible placement and safer setup without running the full conductor through the meter itself.

• 2-wire connection: powered from the monitored circuit
• Included CT can be placed around the conductor—no heavy routing needed
• Back cover enhances safety and hides wiring connections
• Ideal for panel or enclosure mounting with standard cutout

What maintenance and adjustments will I need?

The meter requires minimal upkeep; occasional visual inspection and cleaning are usually enough. If you notice slight discrepancies versus a calibrated reference, use the built-in trimmer potentiometer to fine-tune the displayed values without returning the unit for service.

• Low maintenance: keep the display and vents dust-free
• On-site calibration with integrated trimmer potentiometer
• Replace CT if damaged; the meter itself is a sealed panel device
• Verify readings periodically with a reference meter if precise logging is needed

Who is this for: the DROK Volt Amp Meter suits electricians, hobbyists, small workshop owners, and panel builders who need a compact, combined voltmeter/ammeter for AC systems up to 500V and 200A. It’s especially handy where panel space is limited but simultaneous voltage and current monitoring is valuable, and for anyone who prefers a simple installation using a supplied current transformer and no separate power source.
