Preen’s ADG series is a programmable DC power supply with high power density and high output power, offering great response time, high accuracy and many output voltage and current combinations. With its high performance, ADG series is applied to industries of EV, aerospace, renewable energy, server and battery for R&D testing, quality burning test, or facility power.

With output power up to 100kW per unit, the ADG series offers output voltage up to 1600V and output current up to 2000A. Users can select standard RS-485 interface or optional RS-232 and GPIB. The STEP and GRADUAL modes allow easy setup on test sequence. Depending on CV/CC settings and load conditions, ADG series can operate as a current or voltage source. Its remote sensing feature can effectively reduce voltage drop caused by cable length and provides more flexibility on installation.

User-friendly HMI

ADG series has an intuitive touch screen HMI for easy operation and data display. Users also can easily set up voltage or current variation simulations through the built-in programmable functions in the touch screen.

Fast Transient Response

When output current demand changes rapidly in a large range, the output voltage will decrease or increase significantly in a short period of time. This type of current change sometimes affect the performance of EUT or test results. Having transient response time smaller than 4~12ms, ADG series can fast regulate output voltage to set voltage and minimize the effects to EUT.

Multiple Simulation Modes

STEP and GRADUAL modes allow users to easily set sequences of start / end voltage, run time and current for different testing purposes, or users can contact us to customize different simulation. The standard RS485 interface with Modbus protocol helps increase the length of communication. Optional RS232 and GPIB interfaces are also available.

High Output Voltage + Current = Different Applications

The Preen ADG series has 12 output voltage ranges and 41 models for different industries and applications. ADG series has many output voltage ranges suitable for different market applications. Models over 640V output voltage are applicable for renewable energy, EV, and lithium battery industries. When it comes to circuit breakers, contactors or fuses that require high voltage or current, models with 2000A or 1600V can fulfill the power demands of this type of component testing. The 400V or 320V models can be applied to server related applications due to the increased needs for high voltage DC in data centers.
