concerning these products.
Description
This system power supply is an autoranging GP-IB power supply. It uses power MOSFETs in a 20 kHz switching converter
to provide an autoranging output characteristic with laboratory performance. Output voltage and current are continuously
indicated on individual meters. LED indicators show the complete operating state of the unit. Front-panel controls allow the
user to set output voltage, current and overvoltage protection trip levels. Overvoltage protection (OVP) protects the load by
quickly and automatically interrupting energy transfer if a preset trip voltage is exceeded. Foldback protection can be
selected to disable the power supply output if the unit switches from Constant Voltage (CV) to Constant Current (CC) mode
or vice-versa.
The power supply can be both a listener and talker on the GP-IB, and can be programmed directly in volts and amps. Power
supply status can be read over the GP-IB, and the power supply can be instructed to request service for any of ten
conditions. Upon command, the power supply will measure its output voltage, output current, or OVP trip voltage and put
the value on the GP-IB. New output values can be put on hold and triggered later, allowing the controller to synchronize
multiple power supplies at one time.
The following parameters and features can be controlled via the GP-IB:
•
Output voltage setting (12 bits)
•
Output current setting (12 bits)
•
Trigger (update output)
•
Output disable/enable
•
OVP reset
•
"Soft" voltage and current limits
•
Status reporting
•
Service request capability
•
Foldback protection
•
Output voltage measurement (12 bits)
•
Output current measurement (12 bits)
•
OVP setting measurement
•
Machine state initialization
• 16 machine state presets
• Self test
Output connections are made to rear-panel screw-on terminals. Either the positive or negative output terminal may be
grounded or the output may be floated up to + 550 Vdc (including output voltage) from chassis ground. Output voltage can
be locally or remotely sensed.
The power supply is fan cooled and is packaged in an Agilent Technologies System ll-compatible modular enclosure which
is sturdy, attractive and provides easy access for servicing.
