Thorlabs recommends that the liquid crystal cube controller is operated with the Thorlabs TPS002 Power
Supply, as it was specifically designed for use with this product. However, to enable customers to use the
cube in installations where a ±15 V and 5 V power is already available, the piezo cube can be operated
with a different external power supply, such as a bench or lab supply.
In this case however, extreme care must be taken to ensure that it meets the specifications and is
connected to the cube correctly. Out of tolerance supply voltages or incorrect connection, applied even
momentarily, can result in the sensitive electronics inside the cube getting damaged, invalidating warranty.
The cube uses a standard “mini-DIN” type of input connector, the corresponding plug is available from
most standard electronics suppliers.
Figure 10 below shows the mini-DIN socket as viewed by looking at the rear panel of the cube. The pin
numbering follows the standard for mini-DIN connectors.

5 +5V
Warning
When wiring the mini-DIN plug, ensure that all the ground pins are used and the shield is
connected to common ground. This provides a level of protection against overvoltages due to
loss of ground. A “loss of ground” condition can seriously damage the electronics inside the
cube.
