TOMZN D52-2066 100A Digital AC Energy Meter with Built-in CT

TOMZN D52-2066 Digital Energy Meter in Bangladesh

The TOMZN D52-2066 100A Digital AC Energy Meter is designed to monitor important electrical parameters in residential, commercial and industrial electrical installations. Featuring a built-in current transformer (CT), DIN rail mounting and a digital multi-parameter display, this meter provides a convenient way to observe electrical consumption and operating conditions.

The meter supports AC input voltages from 40V to 300V and current measurement up to 100A, according to the supplied product specifications. Its compact design makes it suitable for compatible distribution boards, electrical control panels and energy-monitoring applications.

Six Electrical Parameters in One Meter

The TOMZN D52-2066 offers six measurement functions in one device:

• Voltage (V): Displays the measured AC voltage.

• Current (A): Monitors electrical current up to the specified 100A limit.

• Power (W): Displays the measured electrical power.

• Energy (kWh): Tracks accumulated electrical energy consumption.

• Frequency (Hz): Displays the measured AC supply frequency.

• Power Factor (PF): Indicates the measured relationship between active and apparent power.

Having these parameters available on one display can help users monitor electrical loads and understand their energy usage without installing separate meters for each measurement.

Built-in CT and DIN Rail Installation

The D52-2066 uses a built-in CT design for current measurement. This integrated arrangement can simplify installation compared with configurations that require a separate external current transformer, provided the wiring and installation requirements are compatible with the intended circuit.

Its DIN rail mounting format is suitable for compatible electrical distribution boards and control panels. Before installation, check the available panel space, terminal arrangement, conductor size and the manufacturer's wiring diagram.

Electrical installation should be performed by a qualified electrician, with appropriate isolation and overcurrent protection.

Digital Display with Energy Reset Function

The meter features a multi-colour digital display that presents electrical readings in an easy-to-read format. The reset button provides a way to reset the energy counter according to the device's supported operation.

This function can be useful when monitoring energy usage over a selected period or recording consumption for specific loads. Confirm the reset procedure and whether the device retains historical readings before relying on it for long-term energy records.

Applications of the TOMZN D52-2066

The TOMZN D52-2066 may be suitable for:

• Residential electrical distribution boards

• Commercial shops and offices

• Electrical control panels

• Individual appliance or circuit monitoring

• Workshop and small industrial load monitoring

• Solar system AC-side energy monitoring, where the electrical configuration is compatible

The meter is intended for monitoring electrical parameters. Do not assume it is an officially approved utility billing meter or a bidirectional solar net meter unless the manufacturer documentation confirms those capabilities.

Warranty and Purchase Information

The TOMZN D52-2066 is supplied with a 6-month warranty, excluding burn damage and physical damage, according to the provided information.

Before purchasing, confirm the product's dimensions, wiring requirements, measurement accuracy and compatibility with your electrical installation. For 100A applications, verify that the conductors, terminals and protective devices are correctly rated.

The TOMZN D52-2066 is a practical option for users who want multiple electrical readings in one DIN rail-mounted meter.
