 =====Description=====
-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.

-Power is supplied to the D2-005 via a standard C13 to Type-B power cord. The power to each electronics module is through a 9-pin D-sub connector 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. There are two 9-pin D-sub connectors on the back of the D2-005. Either or both can be used to power external electronics, however, current is shared between the two connectors. The pin outs are shown in the following figure:
+Power is supplied to the D2-005 via a standard C13 to Type-B power cord. Connections to additional electronics modules are made through 9-pin D-sub connectors via any compatible serial cable. The D2 Electronics implement a "daisy chain" power configuration, in which each subsequent unit can be powered through the unit before it in the chain and does not need to be powered directly by the D2-005. There are two 9-pin D-sub connectors on the back of the D2-005. Either or both can be used to power external electronics, however, maximum rated current is shared between the two connectors. The maximum power rating for the 5V line is 30W (6A), and for the ±15V line is 22.5W (1.5A). The pin outs are shown in the following figure:

-While it is infrequent, the D2-005 may occasionally radiate noise from the side of its chassis onto nearby electronics. This only occurs in some system configurations, and will appear as a signal at the frequency of your mains electricity (typically either 50 Hz or 60 Hz). This noise can easily be removed by moving the D2-005 at least 18 inches (45cm) away from other electronics, rotating it 90° such that the sides of the D2-005 face away, or by moving the entire power supply to a different shelf. To accommodate this, all D2-005's are shipped with a 5' DB9 cable as of January 1, 2022.
