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. General Information 11 A fault indicator (FLT) and remote inhibit (INH) circuit provides additional shutdown protection, should either the GP-IB and/or controller fail. The FLT circuit provides the user with a means of knowing the status of any unmasked fault register bit independently of the SRQ function available through the GP-IB. You don’t have to rely on the controller to inform you of a fault within the power supply. The INH circuit (which is also independent of the GP-IB) controls the RI bit in the fault registers, and provides a way to disable the supply remotely (i.e. a "panic button’’). This gives you a means to bypass the controller and/or GP-IB to disable the supply. Safety Considerations This product is a Safety Class 1 instrument (provided with a protective earth terminal). The instrument and this manual should be reviewed for safety markings and instructions before operation.
