PZEM-022 AC Digital Multi-Meter

Description

The PZEM-022 AC Digital Multi-Meter is a compact and accurate electrical measuring instrument designed to monitor real-time AC voltage, current, power, energy consumption, frequency, and power factor. Tailored for home automation systems, energy monitoring, and industrial electrical panels, this multi-functional meter delivers reliability, safety, and precision in a single easy-to-install unit.

Featuring a bright, easy-to-read digital LCD screen, the PZEM-022 provides clear visual feedback on all parameters, even in low-light environments. It supports single-phase AC input voltage (80–260V) and measures current up to 100A (through an included split-core current transformer). With high accuracy and stable performance, it’s ideal for tracking electrical usage and optimizing energy efficiency in both DIY and professional setups.

The meter is designed with built-in memory to store energy data, even after a power interruption—making it especially useful for long-term monitoring. The device also features overload alarm functionality, allowing users to set thresholds and be alerted when loads exceed safe limits. This is crucial for protecting sensitive equipment and maintaining safe operational standards.

Installation is straightforward, with the included current transformer allowing for non-intrusive current measurement—no need to break existing wiring. It supports DIN-rail mounting, making it perfect for inclusion in breaker boxes, inverter systems, and smart home power management systems.

Whether you are an engineer, technician, or homeowner interested in better managing energy usage, the PZEM-022 AC Digital Multi-Meter offers a reliable and intelligent solution. It’s an essential tool for anyone looking to monitor load behavior, detect irregularities, or improve overall electrical system performance.
