Three-phase 187 ~ 480Vac voltage input range, suitable for worldwide electrical system. 36kW/6U high power density, high conversion efficiency, with ultra-low ripple, fast instantaneous response, to meet the needs of different fields and different stages of testing. This series of power supplies provides one or more 6kW power supply modules, each power supply module is connected across a separate phase of the three-phase AC power supply. The following illustration shows how to install three 6kW power supplies or three 12kW power supplies to achieve balanced current consumption of the three-phase AC power supply.
This series of power supplies supports CC & CV priority selection function to determine whether the output is in voltage high-speed mode or current non-overshoot mode to meet the test requirements of different types of loads. When testing LED loads, users can select CC priority mode to avoid output current overshoot.
This series of power supply supports voltage, current climbing and falling time adjustable, and the setting range is 1ms ~ 24h.
This series of power supplies provide List/Program/Step three modes to edit the output sequence, supporting customers to quickly select according to actual test requirements. After triggering the output, the power supply will automatically change the output according to the edited file. This series of power supplies also supports sequential output of multiple files, and the number of repetitions of each file and the number of executions of the entire sequence file can be set.
<Introduction to the professional version of the power supply function>
The series of power supply built-in sine wave, triangle wave, rectangular wave, trapezoidal wave, sawtooth wave and step and other typical waveform setting interface, convenient for customers to edit and call. In addition to the above standard functions, you can also edit the output of any complex function that can be used for R & D and production tests.
This series of power supplies has built-in German standard DIN40839 standard automotive power network voltage curve and international standard ISO 16750-2 pulse waveform, fast voltage rise/fall response speed, with any function generator function, can more truly simulate the impact of various test conditions on electronic equipment, and is the preferred power supply test instrument for the automotive electronics industry.
This series of power supplies can simulate the I-V curve function of solar panels, providing Curve Mode, user-defined mode, and SAS Mode with built-in standard curve. Using Curve Mode, you only need to set 4 parameters to draw a characteristic curve similar to the solar array. In the custom mode, users can edit the I-V curve of up to 4096 points to achieve dynamic cloud shading effect, which can be applied to the maximum power point tracking (MPPT) performance test of solar inverters. Built-in SAS model, users can simulate I-V curve output and generate reports after simply setting parameters.
This series of power supplies has built-in three-stage charging curves of common battery types on the market. Customers can directly call or modify the switching conditions for entering each charging stage according to actual test data. Moreover, the hardware circuit of this series of power supplies has been optimized. After charging is completed, the power supply will be turned off. At this time, no matter how big the battery voltage is, the reverse current will be as low as about 10mA. Even if there is no anti-battery backflow device, the problem of power supply reverse battery current will be effectively prevented.
This series of power supply supports battery simulation function, which can simulate the real working state of various batteries.
