Voltage controll
We have two power supply units, both controlled by a LabVIEW script via the server. We use a Low Voltage Power Supply Unit (LVPSU), the HMP 2030 by Rohde & Schwarz. The LVPSU powers the LTA with 12 V and 1-2 A and supplies the base power for the CCD. For a High Voltage Power Supply Unit (HVPSU), we use the Keithley 2470 SourceMeter. It is used to deplete the CCD of any free charge, using around 50-70 V. It has very high precision, capable of measuring currents down to femtoamperes. This precision is needed to test for defects in CCDs.
| Voltage Range | Current (A) | Power Management | Max Current at 32 V (A) |
|---|---|---|---|
| 0 - 16 | 5 | Standard | - |
| 16 - 32 | 2.5 | Intelligent Power Management | 2.5 |
