HD VFD dot-matrix display

The ZEL6000 innovatively uses a self-emitting, wide-angle view, and high-luminance VFD dot-matrix display. This guarantees that the display will be clear and stable within the entire temperature range.

Voltage measurement resolution: 0.1mV; Current: 0.1mA

The ZEL6000 adopts a high-speed/high-accuracy ADC and DAC, realizing the synchronous sampling of the voltage and current. This makes the 0.1mV/0.1mA high resolution more authentic while guaranteeing that it meets the test requirements for the majority of power supplies.

Four basic operation modes

The ZEL6000 has CV, CC, CR, and CW functions. This helps users conduct relevant parameter tests quickly and easily.

Up to 10KHz effective dynamic test rate

The ZEL6000 comes with a real dynamic test rate of 10KHz; three control modes (e.g. continuous, pulse, and toggling control); and a linear adjustable frequency/duty cycle and optional trigger modes. Its constant current and rising/falling slope control enable square, triangular, trapezoidal waves of different frequencies and duty cycles to be realized easily.

List test function

With 50μs single-step simulation time, the ZEL6000 can simulate any waveform less than 5KHz and can support 7 list files. Each file can be edited for 84 steps, during which the load time can be set and the edge can be edited to meet the requirements of the majority of waveform simulations.

Automatic test function

The ZEL6000 provides 10 test files, each of which has 10 groups of test data. Any file can be connected randomly. It is easy to check edits made at each step, so that programming is not excessively complicated and the production test is greatly facilitated.

Battery discharge test function

The ZEL6000 provides 10 test files and can program a discharging current. The conditions to stop discharge include discharging time, discharging quantity, and minimum voltage. The discharge will stop upon meeting one of the above conditions. The discharging time and quantity are displayed in real time.

OCP and OPP test functions

The ZEL6000 provides OCP and OPP test functions for helping user measure overcurrent points and overpower points directly and determine the “PASS/FAIL” status of the product.

Constant voltage loading/unloading function

The constant voltage loading function of the ZEL6000 enables its automatic detection of voltage. When voltage rises or falls to the set voltage, the electronic load is able to automatically load/unload, ensuring the normal operation of the power supply to be measured while greatly facilitating the test of a similar power source.

Voltage rising/falling time measurement

The ZEL6000 has functions to measure the voltage rising/falling time. Users can set voltage V1 and V2. The electronic load is able to automatically measure the time when V1 rises/falls to V2 of power supply to be measured. The time is accurate within 0.1ms.

Software protection function and hardware power protection

The ZEL6000 has reverse voltage, overvoltage, overcurrent, overpower, and overtemperature protection measures to comprehensively protect load and the power supply to be measured.

Upper computer control

The powerful upper computer software features a user-friendly design that is easy to use, stable, and reliable. It can conduct various complicated power supply tests; and support the real-time display of voltage, current, resistance, and power. Moreover, it can display voltage and current in a trend graph, which has powerful functions, supports zooming by dragging, facilitates the operation of the electronic load on the computer, and enables a more intelligent electronic load.
