This versatile family of DC power supplies provides laboratory grade performance along with many features to meet both laboratory and system needs.
Ten-turn front panel controls provide the means to precisely adjust the output voltage and current. The settings of these controls can be observed on the front panel meters by pressing the Display Settings button. This allows the current limit to be set when operating in the.
CV mode without shorting the output terminals and the voltage limit to be set when operating in the CC mode without opening the load leads.
Three and one-half digit front-panel meters provide a convenient means for monitoring the output voltage and current. The accuracy of these meters allows them to replace external DVMs and monitor resistors in many applications that require monitoring of the power supply output.
The overvoltage protection (OVP) trip level can also be displayed on the front-panel meters, allowing the trip level to be accurately adjusted without actually activating the OVP circuitry or disconnecting loads. In addition to the protection provided to the power supply and load by the OVP, these supplies also have protection against operating under excessive ac line or thermal conditions.
As autoranging power supplies, these units can operate at their maximum rated power over a wide and continuous range of voltage and current combinations. This often allows both present and future requirements to be satisfied with fewer supplies.
HP Model 6023A is stable when operating in the CC mode into inductive loads up to 1 henry. HP Models 6010A, 6011A, 6012B, and 6015A are stable when operating in the CC mode into inductive loads up to 100 mH, and a special modification is available for these three models to assure stability with loads up to 10 henries.
The output voltage and current of these supplies can be remotely controlled with either 0 to 5 volt or 0 to 4000 ohm analog programming signals. The actual output levels can be monitored without complicated external circuitry by connecting DVMs to the buffered 0 to 5 volt monitor outputs. All programming and monitoring signals are referenced to the same common and are accessed through the rear panel barrier strip.
Either terminal may be grounded, or floated up to 240 volts from chassis ground for the HP 6011A, 6012B, and 6023A, and 550 volts for the HP 6010A and 6015A.
If more output voltage or current is needed than a single unit can provide, auto-series or auto-parallel configurations can be used. Up to four 1000-watt units, or up to two 200-watt units can be connected in auto-parallel, and any combination can be used in auto-series providing up to 240 volts total (550 Vdc for HP 6010A and 6015A) from chassis ground including output voltage. Remote sensing can be used to maintain the CV load effect specification at the load with up to 0.5 volt drop per load lead and sense wires that are less than 0.2 ohm per lead. Operation is possible with up to 2.0 volts per lead; however, load effect specification may be degraded.
