Why Choose This Multifunction Power Meter?

6 Parameters at a Glance: Simultaneously measures and displays AC Voltage, AC Current, Active Power (Watts), Power Factor, Frequency (Hz), and Electrical Energy (kWh) — no need for separate instruments.
Dual Voltage Range Options: Available in AC 50–300V or AC 250–450V range — choose the version that suits your application at the time of ordering.
High-Definition Color LCD Display: Bright, colorful, high-contrast screen ensures readings are clear and intuitive even in challenging lighting conditions.
Auto-Save / Memory Function: Automatically saves the cumulative energy (kWh) reading on power-off. Upon restart, the meter picks up exactly where it left off — ideal for ongoing energy monitoring.
Fast Measurement Speed: Updates readings approximately 2 times per second for near real-time monitoring.
Compact Panel-Mount Design: Small 49×47×52 mm body with a standard Ø22 mm panel cutout makes installation quick and space-efficient in control panels or enclosures.
Built to Last: Constructed from high-quality materials for durable, long-term performance in demanding environments.

Frequently Asked Questions

Q: What does this 6-in-1 power meter measure simultaneously?

A: This multifunction panel meter simultaneously displays AC voltage, AC current, active power (watts), power factor, frequency (Hz), and cumulative electrical energy (kWh) — all on one colorful HD LCD screen without needing separate instruments.

Q: Which voltage range should I choose — AC 50–300V or AC 250–450V?

A: Select the range that matches your electrical system. The AC 50–300V version suits standard residential and light commercial systems (e.g., single-phase 120V or 220V grids), while the AC 250–450V version is suited for higher-voltage industrial or three-phase applications. Please specify your required range when ordering.

Q: Does the meter retain energy readings after a power outage?

A: Yes! The auto-save memory function automatically stores the accumulated kWh value when power is lost. When power is restored, the meter resumes counting from the saved value — making it reliable for long-term energy tracking.

Q: How is this meter installed?

A: The meter is designed for panel mounting. It requires a standard Ø22 mm circular cutout in your enclosure or control panel. Its compact 49×47×52 mm body fits neatly behind the panel face, making installation straightforward for most control cabinets.
