SAFETY SUMMARY
The following general safety precautions must be observed during all phases of
operation, service, and repair of this equipment. Failure to comply with these
precautions or specific WARNINGS given elsewhere in this manual will violate safety
standards of design, manufacture, and intended use of the equipment.
Preen assumes no liability for the customer‘s failure to comply with these
requirements.
1) BEFORE APPLYING POWER
Verify that the equipment is set to match with the power line input.
2) PROTECTIVE GROUNDING
Make sure to connect the equipment to the protective ground to prevent an
electric shock before turning on the power.
3) NECESSITY OF PROTECTIVE GROUNDING
Never cut off the internal or external protective grounding wire, or disconnect
the wiring of protective grounding terminal. Doing so will cause a potential
shock hazard that may bring injury to a person.
4) DO NOT OPERATE IN AN EXPLOSIVE ATMOSPHERE
Do not operate the equipment in the presence of flammable gases or fumes.

5) DO NOT REMOVE THE COVER OF THE EQUIPMENT
Hazardous voltages may be present when the covers are removed. Component
replacement and internal adjustment can be done only by qualified service
personnel.
Warning
LETHAL VOLTAGES. The equipment can supply 1600V peak at its output. DEATH on
contact may result if either the output terminals or the circuits connected to the
output are touched when the power is applied.

1General information
1.1 Introduction
Preen’s ADG-P series is a high power programmable DC power supply with high
power density and high output power, offering great response time, high accuracy
and a wide range of output voltage/current combinations. Designed for the growing
demand of high power DC supplies, the ADG-P series is ideal for testing EV-type
motor/compressor, server power supply, fuse, circuit breaker, contactor and PV
inverter.
With output power up to 100kW per unit, the ADG-P series can offer output voltage
up to 1600V or output current up to 2500A. The 7”touch screen HMI provides
intuitive operation and data display. For communication interface, the user can select
the standard RS-485 or optional RS-232 and GPIB. With built-in STEP and GRADUAL
features, the ADG-P allows easy setup on test sequence. According to CV/CC settings
and load conditions, the ADG-P can operate as a current or voltage source. The
Remote Sensing Compensation capability effectively reduces voltage drop caused by
cable length and provides greater installation flexibility.

2Installation
2.1 Unpacking and Check
Each ADG-P series DC power supply has been carefully tested and taken every
reasonable precaution to ensure that product is not damaged before shipping,
however some damages might occur on the product during shipping. Please inspect
the product carefully after unpacking and save all packing materials until inspection
is complete.
Should any damage be found, please contact the shipping company and Preen, and
provide photos of the damage. Do not return the product to the factory without
obtaining the prior Return Merchandise Authorization (RMA) acceptance from Preen.
2.2 User Preparation
1. The product should be installed in indoor and the environment should be dry,
air-circulated and little dust. The ambient temperature around the product
should be lower than 40˚C. Stay away from liquid, flammable gases, corrosive
substance or heat sources and avoid direct sunlight.
2. Due to the heavy weight, the location for installation must be stable and secure,
and the product is better to be placed on the level ground.
3. For removal and installation of the front door, the front side of the product
should be space with at least 105 cm length. For regular maintenance and
proper ventilation, 80 cm/60 cm clearance from the rear/top side of the
product is required. Do not block the cooling fan opening in case of the internal
temperature getting too high and adversely affect product life.

2.3 Input & Output Connection
For input/output connection, please remove the front door of the product enclosure
which is fixed via screws, the terminals of AC input and DC output are inside the front
door. For safety requirement, ensure that the product and the DUT are switched off
before connection, and screw the front door back after all connections is completed.
Figure 2.1 Remove the front door from the product enclosure
