Energy Meter KETOTEK Single Phase AC 40-300V 100A LCD Power Monitor

Description

Product Overview

The KETOTEK Single Phase Energy Meter is engineered for precise electrical measurement in a compact DIN‑rail format. Constructed from high‑impact ABS that is flame‑resistant, the device meets industrial safety standards while remaining lightweight at just five ounces. Its built‑in current transformer (CT) allows direct connection to circuits without external sensors, simplifying installation on panels ranging from 40 V to 300 V AC and up to 100 A. The meter displays six core parameters – voltage, current, active power, energy consumption, frequency and power factor – on a high‑definition 178° wide LCD that offers backlight illumination for clear visibility in both bright daylight and low‑light environments. Measurement accuracy of 0.01 ensures reliable data for billing, load analysis and energy‑efficiency projects. The unit stores consumption data internally, preserving records even when power is lost, and a five‑second press of the reset button clears the accumulated kilowatt‑hour count for fresh monitoring cycles. With a compact footprint of 2.13 × 2.52 × 3.15 inches, the meter fits easily into standard DIN‑rail slots and integrates seamlessly into existing electrical panels. The included user manual guides users through wiring, configuration and interpretation of the displayed values, making the product suitable for electricians, facility managers and DIY enthusiasts alike. The meter’s 0.01% accuracy class aligns with IEC 62053‑21 standards, providing confidence for commercial billing and regulatory compliance. Its dual‑language display supports both English and metric units, allowing quick conversion between watts, kilowatts and megawatts as needed. The device operates on a 230 V power source and requires no batteries, reducing maintenance costs. The robust ABS enclosure protects the internal circuitry from dust, moisture and accidental impacts, extending service life in harsh industrial environments. Additionally, the meter’s firmware can be updated via a simple USB interface, ensuring future compatibility with emerging smart‑grid protocols. Installation is streamlined by the integrated clamp‑type CT, which snaps onto conductors without the need for disassembly, saving time and reducing downtime. The meter also features a programmable alarm that notifies users when consumption exceeds predefined thresholds, enabling proactive load management. For remote monitoring, the optional wireless module can transmit real‑time data to a cloud dashboard, supporting analytics and reporting for energy auditors. Overall, the KETOTEK meter combines accuracy, durability and user‑friendly design to deliver reliable power monitoring for a wide range of applications.

Usage

Designed for versatility, this energy meter excels in residential, commercial and light‑industrial settings. Homeowners can install it in a utility panel to monitor daily electricity usage, identify high‑consumption appliances and adjust habits to lower bills. Small business owners benefit from real‑time insights into equipment power draw, enabling them to schedule heavy‑load machines during off‑peak hours and avoid unnecessary energy waste. In workshops and maker spaces, the meter provides accurate readings for custom inverter setups, ensuring that non‑standard sine waves are correctly measured and logged. Facility managers in schools or hospitals can deploy the device across multiple circuits to aggregate data, supporting sustainability initiatives and compliance with energy‑efficiency regulations. The meter’s clear LCD display allows technicians to quickly verify voltage and current levels during routine inspections, while the built‑in CT eliminates the need for separate current sensors, reducing installation complexity. Its ability to retain data during power interruptions ensures continuous tracking, which is essential for environments where power reliability is critical. Whether mounted on a standard DIN‑rail in a distribution board or used as a portable diagnostic tool, the KETOTEK meter delivers consistent performance across a broad temperature range, making it suitable for indoor and semi‑outdoor installations. Users can also integrate the optional wireless module to feed data into building‑management software, facilitating automated reporting and predictive maintenance.

FAQ

What voltage and current ranges can this meter measure?

The KETOTEK meter is designed to handle an AC voltage range from 40 V to 300 V and a current range up to 100 A. This broad range makes it suitable for most residential and light‑industrial applications, allowing users to monitor both low‑voltage lighting circuits and higher‑voltage equipment without the need for additional adapters.

How does the data storage work when the power is lost?

Even if the main power supply is interrupted, the meter retains the last recorded consumption values in its internal non‑volatile memory. When power is restored, the device resumes logging from the saved point, ensuring that no usage data is lost. This feature is especially valuable for accurate billing and for environments where power stability cannot be guaranteed.

Can the meter be integrated with a smart‑home system?

Yes, the meter supports an optional wireless communication module that can transmit real‑time data to cloud platforms or smart‑home hubs. By connecting the meter to a compatible gateway, users can view live energy statistics on mobile apps, set alerts for abnormal consumption, and incorporate the data into automated energy‑saving routines.

Is the device safe to install in a standard electrical panel?

Absolutely. The meter complies with IEC safety standards and features a flame‑resistant ABS enclosure that meets fire‑rating requirements. Its built‑in CT clamps securely onto conductors, and the DIN‑rail mounting system ensures a stable, vibration‑free installation within standard panels.

What warranty and support does KETOTEK provide?

KETOTEK offers a one‑year limited warranty covering manufacturing defects and provides dedicated technical support via email and phone. Users can also access a comprehensive online knowledge base, firmware updates, and troubleshooting guides to maximize the meter’s performance throughout its service life.
