Product Overview

The TDC2000 series programmable DC power supply is a high-frequency switching DC power supply utilizing PWM technology, featuring a modular design and advanced DSP digital control technology. It offers constant voltage, constant current, and constant power output modes, capable of automatic crossover transformation while maintaining both control and protection characteristics. It ensures high-precision DC power output with low ripple and rapid voltage/current dynamic response, boasting an efficiency of up to 93%. Compared to traditional thyristor power supplies, the high-frequency switching DC power supply has the advantages of smaller size, lighter weight, lower ripple, higher power factor, and better stability, especially evident in the stability of high-voltage output. The product is primarily targeted at the electronic power production, battery industry, PCB manufacturing industry, as well as communication, PLC power supply, mechanical and electrical aging tests, DC motor testing, automated test system integration, battery charging and simulation, hybrid electric vehicle and photovoltaic inverter testing and research units, and laboratories in need of high-precision DC power supplies. It is used to replace imported medium to high-power DC power supply products.

Input/Output Isolation

Constant Voltage/Constant Current Switching Instructions: Under rated power, voltage, and current output, the desired settings can be freely combined; the output modes are Constant Voltage (CV) and Constant Current (CC), with the output mode depending on the power supply's output voltage, the set current value, and the size of the load resistance. As shown in the figure: Curve 1 and Curve represent loads with different resistances. When Curve 1 intersects with Iset, the power supply operates in CC mode. When Curve 2 intersects with Vset, the power supply operates in CV mode.

You can determine the load's status through a simple calculation:

Here, Vset = set voltage value, Iset = set current value.

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

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

When RL > Rset, the power supply operates in constant voltage mode.
