Disposal of the Product The product must never be dumped in the Municipal Waste. Please check your local regulations
for disposal of electronics products.
Made In Italy : We stress the fact that all the boards are made in Italy because in this globalized world, where getting
the lowest possible price for products sometimes translates into poor pay and working conditions for the people who
make them, at least you know that who made your board was reasonably paid and worked in a safe environment. (this
obviously applies only to the boards marked "Made in Italy", we cannot attest to the manufacturing process of "third
party" boards).

1. Overview
Functional description
The Mod. A7030 –AG7030 is a family of multi channel HV boards, available with either positive or negative polarity,
compatible with the CAEN Universal Multichannel Power Supply System
1
(SY1527, SY2527, SY4527, SY5527).
The A7030 channels share a common floating return, which allows on-detector grounding reducing the noise level;
the floating return is insulated from the crate earth up to ±50 V; the return of the AG7030 channels is wired to the
crate Earth reference.
The output voltage range is 0 ÷ 3 kV, with 1 mA maximum output current and 50mV set and 10mV monitor resolution.
Maximum delivered output power is 1.5W per channel.
The boards are provided with both current and voltage protections.
Two output current limits are foreseen:
•ISet; software limit, individually set for each channel; if exceeded, the relevant channel is signalled in
Overcurrent
•IMax; hardware limit, common to all channels, set via front panel trimmer and monitored via software; if
exceeded 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 module to work as
current generator.
The maximum output voltage can be fixed, through a trimmer located on the front panel, at the same common value
for all the board channels and this value can be read out via software. The boards have also the safety board interlock
(see p. 11).
The HV RAMP-UP and RAMP-DOWN rates may be selected independently for each channel in the 1 ÷ 500 V/s range
(1 V/s step).
The boards are available with 12, 24, 36 and 48 channels; see also table below:

3. Operating modes
The Mod. A7030 –AG7030 boards can be controlled, either locally or remotely, through the SYSTEM software
interface. For details on SYSTEM operation, please refer to the User's Manual of this product. The following sections
contain a description of commands available for the board control and status monitoring.
Output control and monitoring
For each output channel, it is possible, through the system, to access the following parameters:
CHANNEL NAME (settable):
descriptive name for the relevant channel
V0SET (settable):
the first of the two allowed voltage programmable values.
I0SET (settable):
the first of the two allowed current limit programmable values (OVC warning only)
V1SET (settable):
the second of the two allowed voltage programmable values
I1SET (settable):
the second of the two allowed current limit programmable values (OVC warning only)
RUp (settable):
the Ramp-Up parameter value, i.e. the maximum voltage programmable increase rate.
RDWn (settable):
the Ramp-Down parameter value, i.e. the maximum voltage programmable decrease rate.
TRIP (settable):
the TRIP parameter value, i.e. the maximum time an Over Current condition is allowed to last.
SVMAX (settable):
the maximum voltage value programmable for the channel. If the value set as SVMAX is less
than the current value of the V0SET/ V1SET parameter, the latter will automatically decrease
to the SVMAX value.
VMON (monitor):
monitored voltage value
IMON (monitor):
monitored current value
ImAdj
offset value which is added to IMon to adjust its value to zero
STATUS (monitor):
it displays the channel status.
PW (ON/OFF):
the Power parameter shows the ON/OFF channel status. As this parameter is set ON, the
channel is switched on (if the INTERLOCK is not active and if the channel is enabled either
locally or remotely) highlighted in green when channel ON; onstate = ON; offstate = OFF
POn (EN/DIS):
Power-On option, which can be enabled or disabled. If this option is enabled, at Power-On or
after a Restart each channel is restored in the same condition (defined by the Power
parameter) it was before the Power-Off or Reset. If this option is disabled, at Power-On or
after a Restart all the channels are off, independently from the condition in which they were
before the Power-Off or Reset ; onstate = Enabled; offstate = Disabled
PDwn (Kill/Ramp):
Power-Down option, which can be set as KILL or RAMP. It affects the way the channels react
at a Power-Off command caused by a TRIP condition. If the KILL option is selected, the
relevant channel will be switched off at the maximum rate available. If the RAMP option is
selected, the voltage will drop to zero at a rate determined by the value of the Ramp-Down
parameter programmed for that channel; onstate = Ramp; offstate = Kill
TripInt:
2N-bit word (hexadecimal) maximum 16 lines, where N is the number of the board’s Internal
Trip Bus lines. Bits [0;N-1] allow the channel to sense the trip status from the corresponding
lines when set to one; in the same way, bits [N;2N-1] allow the channel to propagate the trip
status over the Trip Bus: bit N on line 0 and so on (see SY4527 User’s manual).
TripExt:
Must be set in the 0÷255 range (hexadecimal). Bits [0;3] allow the channel to sense the trip
status from the corresponding lines when set to one; in the same way, bits [4;7] allow the
channel to propagate the trip status over the trip bus: bit 4 on line 0 and so on (see SY4527
User’s manual).
If the POWER ON option is enabled, as the module is turned ON, the channel is restored to the same
condition it was before the POWER OFF or RESET; if this option is disabled, at POWER ON or after a RESET,
the channel is kept OFF independently from its previous condition.
Channel STATUS Flag
The following messages may be returned by the SYSTEM when monitoring the channel STATUS:
RUP channel ramping up
RDWN channel ramping down
OVC channel in OVERCURRENT condition
OVV channel in OVERVOLTAGE condition
UNV channel in UNDERVOLTAGE condition
VMAX channel reached VMAX condition

CAEN

E-TRIPPED channel OFF due to external TRIP line signal
7
I-TRIPPED channel OFF due to internal OVERCURRENT condition
EXT_DIS channel disabled by board INTERLOCK protection
PWR_FAIL channel OFF due to exceeded power limit (>1.5W)
After a E-TRIPPED, I-TRIPPED, EXT_DIS notification, it is necessary to perform a CLEAR ALARM cycle, before turning
the channel ON.
Moreover it is possible to monitor board parameters, such as measured Temperature, HIMax and HVMax,
and to check board status; the following messages may be returned by the POWER SUPPLY SYSTEM when
monitoring the board status:
UNDER_TEMP board temperature < 5°C
OVER_TEMP board temperature > 65°C
Interlock protection
Fig. 2 –INTERLOCK electrical scheme
In order to enable the HV output channels, first of all it is necessary that SAFETY LOOP pin on the Radiall
52pin output connector is short circuited with the next RETURN pin (pin 21 on A/AG7030 –7030T; pin 10
on A/AG7030L); if the board features SHV connectors, skip this step. Then it is necessary to configure the
Interlock connector as follows:
contact open
INTERLOCK
voltage level (0÷1V, ~5mA current) between pin 2 and pin 3
INTERLOCK
short circuit pin 1 with pin 2, and pin 3 with pin 4
ENABLED
voltage level (4÷6V, ~5mA current) between pin 2 and pin 3
ENABLED
A schematic diagram of the Interlock input is shown in the figure above, where the diode is part of opto-coupler stage.
Interlock means that channel is hardware disabled.
The front panel Interlock LED is ON when the INTERLOCK is active; as INTERLOCK is active, channels are turned off at
the fastest available rate, regardless the RAMP DOWN setting.
Grounding specifications
The Mod. A7030 channels share a common floating return (HVGND), insulated from the crate ground (DGND). This
feature allows on-detector grounding, thus avoiding loops which may increase noise level. HVGND and DGND may be
connected, by short circuiting J1 jumper pins on the motherboard (see figure below).

Safety Earth connection
The connection of return to Earth is fundamental for User safety. The connection must always be at the level of
detector or power supply system. Return connection even if not present or performed incorrectly, due to protection
circuits implemented on the A7030 are bound to Earth; in this case the voltage difference between return and Earth
(System), is limited to approximately 50V. Please note that this is a status of emergency-protection, not a working
one. The Connector Configurator allows to optimize the connection of the return and of DGND (Earth). The best
configuration must be determined by the user upon application, the optimal connection depends on many
characteristics of the related experiment.
The following diagrams show two examples of configuration, namely:
The “closed loop “ Earth configuration (J1 contacts closed)
The “open loop” Earth configuration (J1 contacts open)
