Chapter 3 Installation & Initial Set Up
3.3.2 Using the GPS011 Linear Power Supply
The unit is supplied with a variety of mains power cords.
1) Select the power cord appropriate for your territory.
2) Connect the power cord to the socket on the rear panel of the unit - see Fig. 3.11.
3) Select the correct voltage range for your region.
4) Plug the power cord into the wall socket.

Caution
Both switching and linear power supplies can be used with the Thorlabs galvo
systems, however it is important to limit the inrush current when the power supply
is turned on, in order to ensure that the power supply reservoir capacitors on the
board are not damaged by the large surge currents that can occur on power-up.
Most power supplies naturally “soft start” when they are switched on at the mains
side and provide inrush current limiting. If, however, the power supply is turned on
at the output (DC) side, it can output its peak current instantaneously. In this case it
is important to limit this peak current to less than 2 Amps.
Caution
Selecting the incorrect voltage range will damage the unit.
