SY1527 - SY2527 - SY3527 power supply boards


Channels “zoo”

• HV and LV are used on different detectors /FE Electr.

• Many grounding schemes are used• Floating channel: allows to minimize ground

loop problems • Channel return & chassis ground: various levels

of insulation available.• Polarity: may be fixed or reversible• Naming conventions may be misleading

Let’s try to make things clear!


Channel Typology(Catalog naming)

• HV Power supply boards: channels are polarized and referred to the system ground

• Floating LV/HV Boards: a) channels are floating from the system ground up to 500V on a channel by channel basis (reversible polarity)

b) channels are polarized and insulated from the system ground on a channel by channel basis (fixed polarity)

• Common Floating Return HV Boards: channels are polarized with common return insulated from the system ground (typ. HV boards)

HV Power supply boards (2)

• A173x/B P/N Family: 12/28 Ch. HV boards with 100~500 nA current resolution (used for PMTs)

• A183x/B P/N Family: 12/28 Ch. HV boards with 100~200 nA and 20nA current resolution (used for wire chambers)

• A1821 P/N: 12 Channels, 3 KV, 200 uA or 20 uA positive or negative boards with extremely high (2 nA) current resolution (used for wire chambers)


Floating HV/LV Boards “reversible polarity”

• All channels are floating from the system ground up to 500V (reversible polarity)

Floating LV/HV Boards (a)

• A1510 - A1511 - A1512 - A1519: 12 Ch. 100V to 500V boards, 1 or 10 mA full scale current in a single width (used mainly for silicon/pixel detectors bias)

• A1513A - A1516A – A1517A – A1518A: 6 Ch. Low Voltage floating boards, 15V to 4.5V with currents respectively from 1.5 A to 6 A:a) with sense wires for line drop recoveryb) line drop recovery without the sense wires, only by adjusting a trimmer (used mainly for Front End Electronics supply)

• A1514A: heterogeneous board, 7 Ch., 2x500V, 3x10V, 2x7V (used mainly for silicon/pixel detectors bias & FEE supply )


Remote voltage sensing

• Remote Sensing Line (SENSE +/-) to compensate for the voltage drop over the cable

• Voltage is monitored directly at the load by an high impedance differential amplifier through the sense wires

Line Drop Recovery without sense wires

• LV boards feature a Line Drop Recovery (LDR) system which can compensate for the voltage drop over the connection cables

• Vset is modified according to the Impedance of the cable (Rcable)

• If the User wishes to employ the LDR system a short calibration procedure is required (trimmer)

• Advantages: no need for sense wires• Disadvantages: less accurate than sense wires,

dependent from Rcable variations (e.g. temp.)


Line drop recovery + remote sensing

• Use of sense wires over the first cable segment (A, A’)• the remaining loss (voltage drop over rcable) can be

compensated with the LDR• Advantages: better Vout accuracy, faster recovery to

changesRcable
