Product descriptions from the supplier
Description
The DIN RAIL DC meter's surface panel is designed with two buttons, through which you can query power data and set parameters. There is a lead seal design on the cover plate of the power terminal cover which protects the wiring and prevents the user from changing the wiring and anti-tamper.
Features
RS485 communication: used for parameter setting, data reading; DTL645 protocol/Modbus Protocol.
DC metering: using shunt sampling, high measurement accuracy; can measure DC power, current, voltage.
Alarm function: Over-current alarm: When the current exceeds the CT1 value set by the meter, an alarm event occurs, and the alarm light on the electrical surface panel lights up (yellow light).
At the same time, the value of the corresponding alarm status register will change, and the user can read this register through communication to determine whether an over-current alarm has occurred.
Display: LCD with backlight ,Support Various parameters display,energy data and Instantaneous parameters.
Firmware upgrade: RS485 local upgrade.

Precautions for Using Shielding EnclosuresA shielding enclosure is a metallic structure made of conductive or magnetic materials in various shapes, designed to confine electromagnetic energy within a defined space and suppress radiated interference. A typical shielding enclosure consists of a conductive fabric layered over foam plastic, with a silver-plated woven material bonded onto it to form a soft gasket that occupies most of the loose space. This type is primarily used for civilian applications and is suitable for foam gaskets in eEcho11/06/2025 -

Causes and Preventive Measures of Fire and Explosion in Oil Circuit BreakersCauses of Fire and Explosion in Oil Circuit Breakers When the oil level in an oil circuit breaker is too low, the oil layer covering the contacts becomes too thin. Under the effect of the electric arc, the oil decomposes and releases flammable gases. These gases accumulate in the space beneath the top cover, mixing with air to form an explosive mixture, which can ignite or explode under high temperature. If the oil level inside the tank is too high, the released gases have limited space to expanFelix Spark11/06/2025 -
LTB vs DTB vs GIS: HV Circuit Breaker ComparisonThe basic meaning of a high-voltage circuit breaker is, simply put, that under normal conditions, it is used to open (interrupt, trip) and close (make, reclose) circuits, feeders, or specific loads—such as those connected to transformers or capacitor banks. When a fault occurs in the power system, protective relays activate the circuit breaker to interrupt either load current or short-circuit current, thereby ensuring the safe operation of the power system.A high-voltage circuit breaker is a typJames11/06/2025
