1 About the H3C DP52-52 power adapter

The H3C DP52-52 power adapter is a 12V-input and 52V-output non-isolated regulated DC power

supply. It provides protections against overcurrent output, undervoltage input, and overtemperature

conditions. It is suitable for supplying power to industrial switches for being waterproof, dustproof,

anti-shock, small in size, easy to install, and stable in performance.

Keep good ventilation and heat dissipation during the operating process of the power adapter

to ensure long-term reliability.

•

Use the power adapter in an environment that meets the specified requirements in Table3-1.

•

The potentiometer in the power adapter can be adjusted only by qualified personnel as

required and they must be aware of the impact of the adjustment.

•

Do not operate the power adapter in an environment with volatile gases or flammable

materials.

•

Do not remove the cover from the power adapter. Do not touch, repair, or replace the

components inside the power adapter.

•

operating process of the power adapter.

Safety warnings

•

Once the power adapter enters the protection mode, stop the power adapter immediately and

handle the power adapter according to the relevant maintenance guidelines.

•

Only qualified personnel can connect the power adapter to a power source equipment.

•

Power might be still present on the adapter after it is just shut down. Shut down the adapter

and wait for five minutes before working on the power adapter.

•

Pay attention to the safety signs. To avoid electric shocks and burns, do not touch the location

with your hands directly where there are safety warning signs and high-voltage signs.

Installing the power adapter

The following installs the power adapter on a DIN rail:

1. Wear an ESD wrist strap and make sure the wrist strap has good skin contact and is reliably

grounded.

2. Determine the power adapter installation position on the DIN rail according to the location of

power source equipment and the input and output cable lengths of the power adapter.

3. Thread two cable ties through the power adapter screw holes and through the DIN rail

installation holes, and fasten the cable tie to secure the power adapter to the DIN rail.
