Specifications
Specification
Output Voltage: 0 to -10V, o/p is referenced
to GND.
Remote Sense: Provided on negative
and ground connections,
maximum voltage drop
300mV on power connection
leads.
If sense is not connected
automatically regulates the
front panel voltage.
Voltage Accuracy: ±0.5%, ±25mV. Output
voltage can be monitored
through monitor port.
Voltage Setting: 16-bit resolution.
Number of Channels: 2
Output Current: 1 Amp each channel.
When power is taken from
the PXI chassis current
consumption is limited to
1 Amp total.
Sense Connection: On each output, the sense
connection will compensate
for a maximum voltage drop
of 300mV on power feeds.
Sense connections can
be enabled and disabled
under software control and
include sense of remote
ground.
Load Ripple: <<1mV measured from 10Hz
to 100kHz
Power Source From the PXI chassis or
from an external supply,
software selectable.
External power source is
-12V min for full output
voltage range. Voltage can
be raised to -25V without
damage but may limit
available output current.
Protection: Short circuit protection.
Thermal protection. Chassis
-12V supply is protected by
an active current limiter.
Protected from accidental
application of reverse
voltages to 25V.

PXI & CompactPCI Compliance
The module is compliant with the PXI Specification
2.2. Local Bus, Trigger Bus and Star Trigger are not
implemented.
Uses a 33MHz 32-bit backplane interface.
Safety & CE Compliance
All modules are fully CE compliant and meet
applicable EU directives: Low-voltage safety EN61010-
1:2010, EMC Immunity EN61326-1:2013, Emissions
EN55011:2009+A1:2010.*
Mechanical Characteristics
Single slot 3U PXI (CompactPCI card).
3D models for all versions in a variety of popular file
formats are available on request.
Connectors
PXI bus via 32-bit P1/J1 backplane connector.
Power supply outputs via front panel 25-pin male D-type
connector, for pin outs please refer to the operating
manual.
Monitor: Built in Pickering Interfaces
Monitor allows the use of an
external DMM to measure
voltage and current. Voltage
measurement accuracy is
as the DMM ±30µV. Load
current is measured across
a sense resistor. Accuracy
is 1% ±0.3mA. Accuracy can
be improved by using sense
resistor calibration
Leakage Monitor: Allows the measurement of
leakage current. Maximum
current is 10µA. Accuracy
±2% ±3nA
Load Regulation: Recovers in 20µs from a load
current change of
1 Amp (full load).
On/Off Control: Separate from voltage setting
control. 20µs rise and fall
time (no additional capacitive
load, load current 1A).
