Product overview Product overview

TDC2000 series switching programmable DC power supply is a high-frequency switching DC power supply using PWM technology, modular design, using advanced DSP digital control technology, with constant voltage, constant current, constant power output mode, automatic cross conversion, maintenance Both control and protection characteristics ensure the output of DC power supply with high precision, low ripple, fast voltage and current dynamic response speed, and the efficiency is as high as 93%; compared with the traditional thyristor power supply, the high-frequency switching DC power supply has a small size , Light weight, low ripple, high power factor, good stability, etc., especially high-voltage output stability is particularly obvious; products are mainly positioned in electronic power production, storage battery industry, PCB board manufacturing industry and communications, PLC power supply, electromechanical Aging test, DC motor test, automatic test system integration, battery charging and simulation, hybrid electric vehicle and photovoltaic inverter test research unit, laboratory demand for high-precision DC power supply, used to replace imported medium and high-power DC power supply products.

   Shenzhen Topwood Programmable DC Power Supply Product features

  ◇Using high-speed DSP for PID calculation, direct output PWM, modular design, high power density, small size, greatly reducing the failure rate;

  ◇The control circuit adopts high-speed CPU, with high voltage regulation accuracy and small ripple;

  ◇Using 16bit high-speed ADC to quickly and accurately measure voltage and current values;

  ◇With constant voltage, constant current, and constant power mode output, it can automatically cross-convert to maintain the characteristics of both control and protection;

  ◇It has over-voltage, over-current, over-temperature, and short-circuit protection functions. In the system, over-voltage (OVP) and over-current (OCP) can be set, and the values ​​can be modified;

◇With 9 groups of memories, you can set the commonly used parameters (voltage, current) and call them when you use them conveniently. You can perform 30 groups of different voltage, current, power, rise time, and run time settings at a time, and can do 999999 times continuously Cycle test. The running time can be set to 1ms;

  ◇ Provide embedded intelligent PC monitoring system, with RS232, (RS485) communication interface;

  ◇Digital button operation voltage, current, time setting;

  ◇With line voltage drop compensation function;

  ◇Isolation of input and output;

Constant voltage and constant current switching instructions: Under the rated power, voltage and current output, the desired settings can be freely combined; the output mode is constant voltage (CV) and constant current (CC) modes, and the output mode depends on the output voltage of the power supply , The current setting value and the size of the load resistance. As shown in the figure: curve 1 and curve represent two loads with different resistance values. When curve 1 and Iset intersect, the power supply works in CC mode, and when curve 2Vset intersects, the power supply works in Cv mode.

  It can be judged which state the load is in by simple calculation:

   Here, let Vset=set voltage value, Iset=set voltage value,

  The set load value Rset=Vset/Iset can be obtained;

  If we have an actual load value RL=Vo/Io,

  When RL>Rset, the power supply is working in constant voltage mode,

   When RL
