DFT24Vdc/110Vdc-30DS DC-DC Converter

Product Introduction

AC/DC-DC Converter is specially designed for meeting the requirements of all kinds of communication equipment of communication and electric power departments.

AC/DC-DC Converter adopts the high frequency switching technology and hDS many good points, including high accuracy voltage stabilizing, low output noise, strong capacity of resisting disturbance, small volume, light weight, beautiful external shape, etc.

AC/DC-DC Converter is the ideal configuration supplying power to the communication equipments of different voltage grades

 

Main Characteristics

1. Input and output complete isolation, safety and credibility.

2. Advance current control mode and stable & reliable circuit topological structure.

3. The key parts all adopt the imported components, and main technical indexes are much higher than the national related standards

4. All-around protection functions, output over/under voltage, over current, short-circuit and over temperature protection of whole body

5. Adopt no-mDSter automatic equalized current technology, can parallel connection, convenient to extend the capacity

6. AC and DC input are available, and AC and DC can be fully isolated by electricity

Part 7. Installation and commissioning

A. Installation environment requirements

The equipment must be work in No conductive dust explosion, non-corrosive gDSes and vapors environment.

 Installation environment must to be far away from heat and electromagnetic interference

In addition, it must be leaving adequate enough space to facilitate heat dissipation, cooling air holes and block

1. Environment temperature：-5℃～45℃      

2. Environment Humidity：10%~90%RH

3. The power system must be stable place and no severe shock during Installing.

 

B. Checking Boxing

After receive the parcel, pleDSe open it then check whether all the accessories are complete or not. If there are any problems, pleDSe contact with us immediately.

 

C. Install

 Booting and Shut OFF

1. Closed the AC/DC input switching after power module connect the AC/DC input then the power module(Converter) into the working state

2. The RUN LED will on then will have DC Output voltage

3. The power converter will be stop working after cut off AC input and RUN LED Off then the power converter without output

 

 Function key operating

1. FC /EC DIAL : Used to switch float charge and equal charge

2. MANU /AUTO: Used to switch MANUAL charge and AUTO MATIC charge

Noted: Automatic float equal charge must be compatible with the power monitoring system)

 

Indicator light

1. RUN LED ON (Green) means the power converter work normally with output

2. ALM LED ON (Red) means the power converter is failed or power converter module in a state of self-protection.

 

 DC Output setting

Under normal circumstances, the DC output power module factory set at the following values

1. Float voltage：121.5±0.25V         V_FL。

2. Equal Voltage：130.5±0.25V        V_EQ

3. Output Current limited： 101%-105%             I_LIM

If users need to change the factory setting, according to the following methods to re-set

 

 Setting float voltage

In Floating state, adjust “FC ADJ” potentiometer on the front panel then you can re-set the float voltage.

(Note: The output voltage is higher than 60V, the module will protect and shutdown.)

Setting equal voltage

In equal state, adjust “EC ADJ” potentiometer on the front panel then you can re-set the equal voltage.

Equal voltage will be adjust and change at the same time when the float adjust and it need to re-adjust

 

Set the output voltage should ensure that the output did not enter the current-limiting step-down process, otherwise the actual output voltage will be far more than the required voltage and may cause over-voltage protection shutdown. Can be adjusted in a single module or system no-load cDSe

l Voltage current display calibration

The voltage and current calibration need to be carried out inside the module, RV3 (VDJ) voltage display calibration potentiometer, RV2 (CDJ) for the current display calibration potentiometer.

The power converter Module had be calibrated at the factory
