DH96-EHL3Function

DH96-EHL3Pen segment LCD networkMultifunction TableIt is a device used for medium and low voltage systems（6-35KVand0.4KV）The intelligent device integrates data acquisition and control functions, and has functions such as measuring and calculating basic single circuit AC electricity, accumulating electricity measurement, etc. It has4Road switch input monitoring2Circuit relay output and analog output functions. This table provides communication interfaces to connect with computer monitoring systems and supportsRS485interfaceMODBUSCommunication protocol. The multimeter has peak valley metering 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,Its device appearance

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 the requirements4Grade; Electrical fast transient pulse group anti-interference meets the requirements4Grade; High voltage impact anti-interference meets the requirements4Grade; Surge anti-interference meets the requirements3Grade; The panel protection level meets the requirementsIP54The shell protection level meets the requirementsIP20.

Small size, easy to install

The external dimensions comply withDIN83 × 83DIN96×96、DIN120×120Standard, total length of instrument installation75mm(including terminals), using a self-locking panel installation mechanism, 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.

Main technical parameters

Installation dimensions and wiring diagram

Please carefully read the installation method, wiring, and configuration of the instrument before installation.

2.1. Dimensions and Installation

peacefulInstallation method:
1）On the fixed distribution cabinet, choose a suitable location to open an instrument installation hole (such as:91X91mm）；

2）Take out the instrument and remove the fixing clip;

3）Insert the instrument into the instrument hole of the distribution cabinet for installation;

4）Insert the fixing clip of the instrument.

2.1.2Terminal wiring

Upper row: Power supply and functional output（15Core)

Note: The terminal wiring in the above table is for illustration only. The specific terminal wiring should be based on the actual terminal wiring on the instrument!

1） Auxiliary power supply: Our company's power instruments have universal capabilities（AC/DC）The power input interface, unless otherwise specified, is provided220V (AC/DC)perhaps110V (AC/DC)The standard product for power interface, the maximum working power voltage of the instrument isAC/DC：85-265VTo prevent damage to the product, please provide a power supply suitable for our company's products.

explain:

AIt is recommended to install AC power supply on the live side1AThe fuse.

BFor areas with poor power quality, it is recommended to install surge suppressors in the power circuit to prevent lightning strikes, as well as fast pulse group suppressors

2) Input signal: The calculation method of collecting data separately for each measurement channel is adopted to ensure complete consistency and symmetry during use. It has multiple wiring methods and is suitable for different load forms. Specifically, as follows:

explain:

AVoltage input: The input voltage should not exceed the rated input voltage of the product（100Vperhaps400V）Otherwise, consideration should be given to usingPT, must be installed at the voltage input terminal1AFuse;

BCurrent input: The standard rated input current is5A, greater than5AThe situation should be handled externallyCTIf usedCTIf there are other instruments connected, the wiring should be in series. Before removing the current input connection of the product, be sure to disconnect it firstCTPrimary circuit or short-circuit secondary circuit. Suggest using a wiring harness instead of directly connectingCTFor easy disassembly and assembly;

CEnsure that the input voltage and current correspond, the phase sequence is consistent, and the direction is consistent; Otherwise, numerical and symbol errors may occur!! (Power and electrical energy);
