Overview
The power supplies of the A1542 family house 32, 24 or 12 independent high voltage channels. The A1542 is available in different versions equipped with SHV or with DB25 connector:
|
DB25 connector
Single width (5 TE wide), 24 channels for Mod. A1542LP, A1542LN |
|
SHV connector
Single width (5 TE wide), 12 channels for Mod. A1542DN, A1542DP, A1542SM |
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 ÷500 V, (10 mV step) with 1 mV monitor resolution. The maximum output current is 1 mA, (20 nA step) with 1 nA monitor resolution. The board is available with either positive or negative output polarity. Mixed version with 6/12 positive and 6/12 negative channels are also available (only with SHV connectors). The boards are provided with both current and voltage protections. The HV RAMP-UP and RAMP-DOWN rates may be selected independently for each channel in the 1 ÷ 100 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. |
