 The Power Supply is a quiet, linear power supply providing +/-15V and 5V. It is in a separate box to isolate 60 Hz and EM interference. One power supply can power two complete laser systems, or four electronics modules.

+Always turn off the D2-005, make connections to the device, and then re-energize the D2-005.  Never connect this D2-005 Power Supply to a device when it is switched on and supplying power.

+If you are considering using an Uninterruptible Power Supply (UPS) to guarantee operation of your Vescent products through a brown out or black out, great care should be taken in choosing the model.  Lower cost models tend to produce modified square wave voltage profiles.  The high-frequency components of such a voltage profile may interact poorly with the D2-005 (and down-stream active Vescent modules).  If you do choose to use a UPS, select a model that will provide a sine wave voltage profile without higher harmonic components to avoid potential damage to your high-value equipment.

 The power to each electronics module is through a 9-pin D-sub connector through a power bridge unit.  The unit can also be powered through any serial cable with 9-pin D-sub connectors, which is convenient when the unit must be taken out of line for access to the side panels.  The pin outs are shown in the following figure:
