IT8300 DC electronic load functional characteristics

Dynamic testing function

The IT8300 series energy feedback DC electronic load can perform dynamic testing function in CC mode. According to the set rules, the electronic load can switch between two set parameters to test the dynamic characteristics of the power supply and check its own stable ability when the pulling current changes step by step. The dynamic testing mode can be divided into continuous mode, pulse mode, and flip mode.

List function

The List mode of the IT8300 series energy feedback DC electronic load can accurately and quickly complete complex and arbitrary current change patterns, and synchronize with internal or external signals to complete precise testing of multi level load, helping customers greatly save costs. By editing the step value, pulse width, and slope of each step, multiple complex sequences can be generated, allowing users to complete various load waveform tests. And in CC mode, the IT8300 series can set the rising and falling edge speeds.

Ultra high energy recovery efficiency can reach up to 95%

The IT8300 series energy feedback DC electronic load is different from ordinary energy consuming electronic loads. Its main feature is to provide a unique energy recovery function, which can recover electrical energy and directly utilize it in the factory, rather than consuming it in the form of heat energy. Its conversion efficiency can reach up to nearly 95%, which not only greatly reduces users' electricity costs, but also avoids the use of air conditioning or expensive refrigeration systems, reducing noise.

Accumulating power, the energy-saving effect is clear at a glance

The IT8300 series energy feedback DC electronic load utilizes power electronic conversion technology to recycle and reuse the output energy of the tested power source on the premise of completing power testing experiments. Through internal high-speed voltage and current sampling, users can directly view the current electrical parameters, including voltage, frequency, and power of each phase, on the instrument panel. You can also view the total power, current feedback total power, and historical feedback total power, making the energy-saving effect clear at a glance. After power failure and restart, the IT8300 series can continue to accumulate on the basis of the battery level before the last shutdown.

High power density

Ordinary energy consuming electronic loads not only consume energy and electricity, but also have a large volume and weight. A 10KW energy consuming load has a minimum volume of 12U, making it difficult to transport and costly. The IT8300 series energy feedback DC electronic load adopts a high power density design, which can provide up to 10.5KW of power absorption within a 3U volume. With the same output power, the volume has decreased by 76.9%.
