Master/Slave Parallel Operation

ADG+ The output power of the ADG+ series is up to 300kW per unit, which can be expanded to 1800kW through simple master-slave operation (max. 6 units). User can simply operate the master unit, the slave unit will receive and reply the data accordingly and equally share the load current. ADG+ series is one of the few high-power DC power supply with parallel feature on the market. The availability for single-unit and parallel operation provides greater flexibility for application.

Remote Sensing Compensation

In the factory or laboratory, there is often a certain distance in the configuration of power and load. The Remote Sensing of ADG+ series is able to compensate the voltage drop caused by the cable length, so the user can avoid the inconvenience of adjusting the voltage.

Solar Array Simulation (opt.)

ADG+ high power programmable DC power supply options solar array simulation function, which can be programmed from the front panel without a need for a controller. Using built-in SAS mode, only four input parameter are needed to establish an I-V curve, which simulates solar panels under different irradiation and temperature. Using built-in EN50530 mode, the I-V curve is established according to the solar cell material (C-SI or thin film), and the user can program the output according to the irradiation and temperature; in addition, the user can also define I-V curves based on different material characteristic to simulate various solar cell materials.

SAS Testing Mode

Using SAS mode, user can set Voc, Isc, Vmpp and Impp according to the spec of PV inverter, then the DSP control system performs P-V and I-V curve calculation accordingly. The dynamic irradiation adjustment is also available during output.

EN50530 Testing Mode

Mainly used for grid-tie inverters, the EN50530 Testing Mode features solar cell model of C-SI/thin-film and the feature of dynamic irradiations/temperature adjustment, user can verify the performance of the inverters: static & dynamic MPPT tracking efficiency, conversion efficiency and overall efficiency.

Solar Array Simulation Control Software (opt.)

ADG+ series options I-V curve remote control software with parameter setting and output waveform display to verify Dynamic & Static MPPT Efficiency of SAS mode and EN50530 test regulations.

Complimentary Control Software and Various Communication Interfaces

ADG+ series offers complimentary remote control software, Preen Program. This graphical user interface provides easy settings and user-friendly configurations for users to fully control the unit. The Preen Program includes GENERAL mode or PROGRAMMABLE mode with STEP and RAMP features available. The preview waveform and report functions also greatly enhance convenience for on review parameters and results before or after testing.
