Wide Voltage and Current Range

Preen's ADG-L series has 14 different models with three output power levels , 4kW , 8kW and 12kW. Withup to 1000V output voltage and multiple Auto Range models , the ADG-L series covers a wide range of applications including electric vehicle , photovoltaic , battery , DC/DC converters and electronic products.

Auto Range Models

Comparing to conventional DC power supplies that provide the same rated current at all output voltage, the ADG-L's auto range models offer a wide operation region. It can generate a higher output current at lower output voltage , or a higher output voltage at lower output current. This feature is an ideal solution for both high current/low voltage and low voltage/high current DUT , and makes one unit to cover a wide range of applications to further save cost and space.

Intuitive Touch Screen and Rotary Knob

The ADG-L series employs 5"touch screen and rotary knob to provide intuitive and easyto-use control and display. Users can quickly access output settings , measurements ,sequences and system configurations from the touch screen. Sophisticated sequences can not only be set from the PC but also easily from the touch screen.

Remote Sense Function

In many laboratories or factories, the DC power supply is located a certain distance away from the DUT, and this sometimes causes voltage drop due to the resistance of the wires.The ADG-L is equipped with remote sensing to compensate voltage drops and provide a stable output voltage,and it allows users to have the desired voltage appear at DUT.

High Power Density: 12kW in 3U

Employing PWM technology and DSP-based control , Preen’s ADG-L series DC power supply has 12kW available only in 3U package , and with parallel configuration , 24kW only has 6U height. The rackmount enclosure is designed to accommodate a wide range of applications , especially for automatic test systems and integrations.

Industry-leading Performance

The ADG-L series is designed for low ripple, high accuracy and tight regulation for simulating different DC voltages. With fast transient response and rise time, the ADG-L DC sources are ideal to test DUT behavior to voltage sags, dropouts, ON/OFF tests and complex DC waveforms.

0.99 Input Power Factor

The ADG-L series is equipped with active Power Factor Corrector (PFC) to enhance input PF up to industry-leading 0.99, which helps reduce the interference on the grid.

Free Control Software

The ADG-L series can be controlled via the Preen Program to configure sophisticate sequences, save/recall STEPs , and generate test result reports. This intuitive control software makes remote programming no longer a difficult task.

Various Communication Interfaces

The DC power supply is equipped with RS-232/RS-485 (MODBUS) for standard interfaces. Optional Ethernet , USB , GPIB and RS-232/RS-485 (SCPI) are also available for better integrations with automatic test systems and the needs of industry 4.0.

Applications

Photovoltaic (PV), electric vehicle (EV), battery charge simulation, fuse and contactors.
