The Preen Preen ADG-PLUS-640-117 Programmable High Power DC Power Supply, 640V/117A, 75kW is a high-power-density programmable DC power supply. With the design of DSP control, it offers a great response time and high accuracy. The self-developed high power module enhances stability and heat dissipation, thus improving product quality. The output mode of CV, CC and CP are fully equipped. The ADG-PLUS-640-117 is ideal for testing EV motor/compressor, server power supply, fuse, circuit breaker, contactor and PV inverter.

For communication interface, the user can select the standard RS-485, RS-232, Analog Control, Ethernet, USB and optional GPIB. The ADG-PLUS-640-117 also comes equipped with remote control software for users to control with ease via PC. The ADG-PLUS-640-117 is CE and RoHS certified.

Intuitive Touch Screen and Rotary Knob

The ADG-PLUS-640-117 employs 7 in. touch screen and rotary knob to provide intuitive display and easy-to-use control. The built-in programming function has been upgraded, so not only can complex sequences be set from a PC, but also from the touch screen. An emergency stop button is equipped for quick shut down, thus enhancing the product's safety. Users can quickly access output settings and measurements, including voltage, current and power.

Master/Slave Parallel Operation

The output power of the ADG-PLUS-640-117 is 75kW per unit, which can be expanded through simple master-slave operation (max. 5 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-PLUS-640-117 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.

Complimentary Control Software and Various Interfaces

The ADG-PLUS-640-117 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 reviewing parameters and results before or after testing.

Programming Sequences and Simulations

The built-in programming function of the ADG-PLUS-640-117 is consisted of GROUPs and STEPs. Users can set output voltage, output current and time to generate step or consecutive voltage/current changes, and set different rise/fall time according to their requirement. This built-in function and the ADG-PLUS-640-117's control software allow users to create complex DC waveform with sophisticated coding - making programming the DC power supply an easy task.

EV Testing Applications

EV Motor Controlling - Motor controlling is the core component of any electric vehicle. It controls the initiation, speed, movement and direction of the motor drive, and converts the electrical energy of the battery to the motor drive.

DC/DC Converters - Power batteries of electric vehicle convert DC high voltage to DC low voltage through DC/DC converters, such as 12V/24V of car lamps, wipers and car stereos. The ADG-PLUS-640-117 features high power and high voltage and is suitable to simulate power batteries on different working conditions, such as voltage dip(sag), and voltage ramp or missing. From R&D verification to HALT/HASS Accelerated Life Testing, ADG-PLUS-640-117 is an ideal choice for DC power supply.

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-PLUS-640-117 is able to compensate the voltage drop caused by the cable length, so the user can avoid the inconvenience of adjusting the voltage.

Device Protection

The ADG-PLUS-640-117 has multiple levels of protection, including over-voltage, over-current, over-power, over-temperature, line-drop-compensation, over-voltage, input over-voltage, input unbalance and to shut down the power supply and prevent fault conditions and further damages.
