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. Designed for the increasing demand of high power DC, ADG is ideal for testing EV’s motor/compressor, server power supply, fuse/circuit breaker/contactor, and PV inverter or can be used as a facility power or EMC chamber power.

With output power up to 100kW per unit, the ADG series offers output voltage up to 1600V and output current up to 2500A. Users can select standard RS-485 interface or optional RS- 232 and GPIB. The STEP and GRADUAL modes allow easy setup on test sequence and 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.
 

High Voltage and High Current Models
 

Preen’s ADG series are one of the few models in the industry that can deliver output voltage up to 2000V and output current up to 2500A, which makes ADG series an ideal DC source for all kinds of component testing.
 

A Variety of 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.
 
New DPS Technology Design Event Log Function
 
ADG series’ touch screen has the built-in event log function that allows users to view error history. This helps user to keep track on the power supply’s operation and better analyze the test results.

Over 12 Voltage Ranges and 64 Models
Variety of Output Power, suitable for different applications   4kW~300kW
ADG Series has over 12 output voltage ranges and 64 models, which are suitable for a variety of industries and applications. New ADG-L series also comes with AUTO RANGE models, which provide more flexibility for testing and simulations.

Easy Remote Control Set Up
ADG-P series comes with RS-485 interfaces and optional RS-232 and GPIB interfaces, allow user to easily programming the unit through different interfaces or Preen’s control software. ADG-L series’ standard interfaces are RS-232, RS-485 and Analog and optional interfaces are GPIB, USB and Ethernet.

Technically Advanced Performance ADG series has the industry leading performance on ripple, response time, and voltage regulation, which make it an ideal DC power supply for all kinds of testing.

Multiple Simulation Functions The built-in STEP and GRADUAL modes allow users to set up sequences of start / end voltage, run time and current for different testing simulations. Or users can contact us to customize different built-in voltage and current simulations for easy testing set up.
