1. Introduction
To all residents of the European Union
Important environmental information about this product
This symbol on the device or the package indicates that disposal of the device after its lifecycle could harm
the environment.
Do not dispose of the unit (or batteries) as unsorted municipal waste; it should be taken to a specialised
company for recycling.
This device should be returned to your distributor or to a local recycling service.
Respect the local environmental rules.
If in doubt, contact your local waste disposal authorities.
Thank you for buying the PS3003! The PS3003 is a highly accurate, DC-regulated power supply with an adjustable
output. This output can be used for constant voltage (C.V.) and constant current (C.C.).
The output voltage can be adjusted between 0V and 30V when the device is in the constant voltage mode or C.V.
mode. The current-limiting point (max. ± 3.5A) can be set arbitrarily in this mode.
The output current can be adjusted continuously between 0 and 3A in the constant current mode.
The output current and voltage are indicated through LCD displays.
