ALLNET ALL369x-A200 / Power Meter induction clamp set 200 A content_copy

This product is a 3-piece set of induction clamps for use with the ALLNET power meters ALL3690 and ALL3691. It is designed for measuring alternating current in three-phase networks, with each clamp intended for one phase. The clamps are rated for current strengths up to 200 amperes per phase, enabling monitoring of power consumption in industrial or commercial facilities. The inner diameter of the clamps is 20 mm, allowing installation on conductors with a corresponding diameter. Each clamp is equipped with a connection cable featuring a plug and a length of approximately 180 cm. These cables serve to connect the clamps to the power meter, enabling transmission of measured values.

Induction clamps are a central component in current measurement, as they detect current flow in a conductor without direct electrical contact. This is achieved through electromagnetic induction, allowing safe and uninterrupted measurement. The clamps are specifically designed for use with the ALLNET power meters ALL3690/ALL3691, which are used in building automation and industrial electronics. Measurement occurs in real time, enabling capture of current consumption, power factor, and other electrical parameters.

Applications include primarily monitoring energy consumption in industrial facilities, commercial enterprises, or buildings with complex electrical installations. The clamps are suitable for use in environments with high current loads, with a maximum current per phase of 200 amperes. When combined with the power meters ALL3690/ALL3691, central data collection and evaluation is enabled, which can be used for energy efficiency analyses or optimizing operational processes.

Functions and equipment in detail include three induction clamps with an inner diameter of 20 mm, each connected via an 180 cm long connection cable with a plug. The cables are designed for secure and reliable connection to the power meter. An important note is that the current clamps must never be connected without load, as this may cause measurement errors or damage. Additionally, a correction factor of approximately 0.2 to 0.25 must be entered in the power meter to ensure measurement accuracy. This factor accounts for the specific characteristics of the clamps and ensures precise display of actual current values.

Technology explained simply is based on electromagnetic induction, where a changing magnetic field (generated by current flow in the conductor) induces a voltage in the clamp. This induced voltage is transmitted via the connection cable to the power meter, where it is converted into current values and displayed. The clamps are passive, meaning they require no external power supply, and operate contactlessly. Measurement occurs without interrupting power supply, which is advantageous for running systems.

Compatibility and accessories include use exclusively with the ALLNET power meters ALL3690 and ALL3691. Additionally, the datasheet references the accessory ALLNET MSR Powermeter Central Unit ALL3696, which is also equipped with induction clamps and intended for IP-based building automation. The central unit ALL3696 provides a central interface for data transmission and can be combined with additional sensors to create comprehensive energy monitoring systems.

Installation and mounting is performed by clamping the conductors to be measured with the induction clamps. The clamps are designed to be easily opened and closed to insert the conductors. The connection cables are plugged into the corresponding inputs of the power meter. Installation does not require interruption of power supply, as measurement is contactless. The clamps are designed for industrial environments and should be mounted according to specifications to avoid measurement errors.

Operational advantages include simple and safe installation, contactless measurement, and real-time monitoring of current consumption. The combination with power meters enables central data processing, which can be used for energy efficiency measures and optimizing operational processes. The clamps are robust and suitable for use in environments with high current loads. Adhering to the guidelines regarding load and correction factor ensures high measurement accuracy.
