DH96-EL3 Pen Segment LCD Network Multifunctional Table

Functions of DH96-EL3

The DH96-EL3 pen segment LCD network multifunctional meter is an intelligent device used for medium and low voltage systems (6-35KV and 0.4KV). It integrates data acquisition and control functions, and has functions such as measuring and calculating basic single circuit AC electricity, accumulating electricity measurement, etc. It has 4 switch input monitoring, 2 relay outputs, and analog output functions. This table provides communication interfaces for connecting with computer monitoring systems and supports RS485 interface MODBUS communication protocol. The multimeter has peak valley measurement and capacity limiting functions. When the capacity reaches the limit value, the multimeter drives the circuit breaker to disconnect the power supply through the intermediate relay.

1.2. Characteristics of DH96-EL3

DH96-EL3 has powerful data acquisition and processing capabilities

It has three-phase voltage, three-phase current, average voltage and current, total active power, total reactive power, active and reactive power of each phase, power factor, power factor of each phase, system frequency, total active energy, total reactive energy, active and reactive energy of each phase. (According to the user's ability to add multiple rate functions, measurement and calculation functions for total harmonic distortion rate of voltage and current, current, 2-31st harmonic components of voltage, etc.)
It has 2 relay control outputs and can be expanded to 4 channels.
It has a maximum of 4 switch input functions and can be expanded to 6 channels.
It has analog output function and can choose 1-2 channels.
It has 50 event recording functions, which can save real-time switch input and relay output events that occur. (Only instruments with optional harmonic function have this function)
You can view various electrical parameters, operating status, etc. of a circuit and switch locally; You can view or set operating parameters and perform operations such as closing and opening.

High safety and good reliability

Multiple anti-interference measures were adopted in the design process, which enables stable operation in the power system environment. Electrostatic discharge anti-interference meets level 4; The anti-interference performance of the electric fast transient pulse train meets level 4; High voltage impact anti-interference meets level 4; Surge anti-interference meets level 3; The panel protection level meets IP54, and the shell protection level meets IP20.

.Small size, easy to install

The external dimensions comply with DIN83 × 83, DIN96 × 96, and DIN120 × 120 standards. The total length of the instrument installation is 75mm (including terminals), and it adopts a self-locking panel installation mechanism, which can be installed without screws.

The system wiring is convenient and flexible

The system wiring methods include three-phase four wire system and three-phase three wire system. (Users can set it themselves, but the wiring diagram needs to be changed)

Intuitive display and easy operation

The large-sized dedicated LCD module can display multiple information in real time, coupled with bright backlight, allowing operators to accurately read data even in poor lighting conditions. The operation method is user-friendly, and the operator can quickly master it. Reading data and setting parameters will become simple and easy to operate.
