The STEP & RAMP modes allow easy setup on the test sequence and depending on CV/CC/CP settings and load conditions, the ADG+ series can operate as a current or voltage source.

EV Motor Controlling

Motor controlling, as the core component of an electric vehicle, controls the initiation, speed, movement, and direction of the motor drive converts the electrical energy of the power battery and provides it to the motor drive. ADG+ series has many high voltage models to simulate the power battery of an EV for motor controlling verification or aging testing.

DC/DC Converters

Power batteries of electric vehicles convert DC high voltage to DC low voltage through DC/DC converters, such as 12V/24V of car lamps, wipers,s and car stereos. Featuring high power and high voltage, ADG+ series is suitable to simulate power batteries in different working conditions, such as voltage dip(sag), and voltage ramp or missing. From R&D verification to HALT/HASS Accelerated Life Testing, the ADG+ series is an ideal choice for DC power supply

The ADG+ series employs a 7” touch screen and a rotary knob to provide an intuitive display and easy-to-use control. The built-in programming function has been upgraded, so not only can complex sequences be set from the PC, but also from the touch screen. The emergency stop button is equipped for quick shutdown, thus enhancing product safety. Users can quickly access output settings and measurements, including voltage, current, and power.

• The upgraded HMI and 7'' colored touch screen can clearly display the parameters and status of the product, and combined with the built-in programming function, the user can easily perform various simulations.
• The rotary knob can be used for fine-tuning and quick selection to improve the convenience of operation.
• An emergency stop button is used for quick shutdown, thus enhancing the protection function and meeting the requirement for the laboratory-related testing field.

ADG+ The output power of the ADG+ series is up to 100kW per unit, which can be expanded to 500kW through simple master-slave operation (max. 5 units). Users can simply operate the master unit, and the slave unit will receive and reply to the data accordingly and equally share the load current. ADG+ series is one of the few high-power DC power supplies with parallel features on the market. The availability of single-unit and parallel operation provides greater flexibility for application.

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

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 parameters 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 the different material characteristic to simulate various solar cell materials.

• Static and dynamic MPPT efficiency test (with optional remote-control software)
• Simulation of IV curve under different irradiation and temperature
• Complied with standard SAS, EN50530, Sandia test regulation
• IV curve can be user-defined and edited via remote control software
• Simulation of output characteristics of various solar cells (S-CI and thin film)
• Accurate voltage and current measurement

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

• Voc – open circuit voltage
• Vmp – voltage at the max. PowerPoint on the curve
• Isc – short circuit current
• Imp – current at the max power point on the curve

Mainly used for grid-tie inverters, the EN50530 Testing Mode features a 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.

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 review parameters and results before or after testing.

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.
