Overview
The power supply A1539B houses 32 independent high voltage channels. A1539B is equipped with DB25 connector:

Single width (5 TE wide), 32 channels for Mod. A1539 |
Consult our connectors reference page for technical information.
The channels share a Common Floating Return, which allows on-detector grounding, reducing the noise level. The output voltage range is 0 ÷100 V, (10 mV step) with 1 mV monitor resolution. The maximum output current is 20 mA, (200 nA step) with 20 nA monitor resolution.
A1539B is provided with both current and voltage protections. If overcurrent occurs, the relevant channel can be programmed either to turn off after a programmable trip time or to keep on providing the maximum allowed current: this particular feature allows the modules to work as current generator. The maximum output voltage can be set through a potentiometer to a value which is common to all channels and can be read out via software. Channel can be enabled or disabled through the Interlock logic. The HV RAMP-UP and RAMP-DOWN rates may be selected independently for each channel in the 1 ÷ 50 V/s range (1 V/s step).
Safety features allows the module to perform as a current generator and includes:
| Channels | can be enabled or disabled through the Global Interlock logic. |
| Overvoltage and Undervoltage warning | when the output voltage differs from the programmed value. |
| Overcurrent detection | When a channel attempts to exceed the programmed current limit, it signalled to be in “overcurrent” and enter in a TRIP status. The output voltage is varied to keep the current below the programmed limit for a programmable TRIP time, then the channel is switched off. If TRIP is set to “constant current mode”, the channel behaves like a current generator. |
| Hardware VMAX | Maximum output voltage can be set, via front panel potentiometer, at the same common value for all the board channels. VMAX value can be read out via software. |
| Safety Board Interlock | This protection allows to disable the primary HV generation when the HV outputs are not connected to their loads. |
