HP 6033A Adjustable Power Supply - Fully Tested

Description

HP 6033A Adjustable Power Supply
*All of our equipment has been fully tested.
These HP-IB CV/CC dc power supplies have many productivity-oriented features which make them easy to program, integrate into systems and use.
A conventional power supply subsystem capable of monitoring and controlling power supply voltage and current requires a variety of hardware in addition to the actual supply.  These new power supplies, however, have built-in capabilities which eliminate the need for D/A programmers, DVMs, and associated auxiliary circuitry.  Fewer instruments mean less rack space, easier calculation of system specifications, quicker configurations, higher system reliability, more rapid troubleshooting, and simpler software.  As autoranging power supplies, these models can provide a wide and continuous range of voltage and current combinations at the maximum rated power.  This often allows both present and future requirements to be satisfied with fewer supplies, also reducing the number of instruments in the system
Front Panel Control
Most of the extensive programmable instruction set can be simulated with front panel controls, thus facilitating design and debugging of system hardware and software.  During system operation, if local control is not needed, the front panel controls can be disabled with a computer command.  If operator interaction is required, a computer command can place limits on the output voltage and current available.  Often, control and monitoring via the front panel is very useful during system development, but not needed afterwards.  If the system is reproduced without further development, power supplies without front panel controls and meters (Option 001) can then be used (except HP6035A).  Ordering your power supplies with Option 001 significantly decreases the cost.
Protection Features
Because of the delicate nature of most loads, these system power supplies provide several different types of protection.  Since they are CV/CC supplies, both the output voltage and current will be automatically limited to the programmed values.  If reaching a programmed value indicates an undesirable condition, the power supply can be instructed to automatically down-program the zero output.  For example, if the programmed current limit is reached while testing a PC board assembly, it may indicate a shorted component.  In this case, the FOLDBACK feature, if enabled, would be able to serve as an over-current protection circuit and down-program the power supply automatically.  FOLDBACK can be enabled and reset over the HP-IB.
The built-in overvoltage protection circuit is adjustable with a front panel control.  The set trip level can be displayed on the front panel meter and also can be read back over the HP-IB, thus making adjusting the level easy.  The OVP circuit, once tripped, can be reset over the HP-IB.
Production procedures sometimes require the operator to adjust the output voltage or current of a power supply locally with the front panel controls.  If this is done, programmed levels can be set to limit the available adjustment range to a safe margin.
Potentially harmful conditions, such as overtemperature and high or low ac input, will trigger the power supply to automatically down-program to zero output.  When these conditions occur, or the FOLDBACK  or OVP circuits trip, LEDs on the front panel light to indicate the failure.  This status can also be read back to the computer over the HP-IB and can be used to generate interrupts.
Programmable Features
Below are the parameters which can be programmed on the HP6030A-6038A and the information is available for readback over the HP-IB.  All of these features are included with the standard programming language or TMSL (Test and Measurement Systems Language).

System Configuration
Up to 16 power supplies can share one HP-IB address, while still providing full independent control, when connected with a modular telephone-style cable.  (This feature requires programming in TMSL mode.)  To use this feature, you will also need to order a serial link cable for each unit to be added to the chain, with the first unit connected directly to HP-IB.  The standard serial link cable is 2 meters (6.6').
If your application requires more power than the output capability of a single unit, you can use an auto-series connection for greater output voltage or an auto-parallel connection for greater output current.  Consult your local HP sales office regarding restrictions/limitations for auto-series and auto-parallel operation.
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 which are less than 0.2 ohm per lead.  Operation is possible with up to 2.0 volts drop per lead; however, the load effect specification may be degraded.
Either terminal may be grounded, or may be floated up to ± 240 (± 550 volts for the HP 6030A and 6035A) volts from chassis ground.
Analog programming inputs and monitoring terminals are provided on the rear panel in addition to the HP-IB programming capabilities.  Zero to full scale voltage or current can be programmed with either 0-5 volt voltage signals, or 0-4000 ohm resistance signals.  The monitoring terminals present 0-5 volt buffered signals which are proportional to the output voltage and current.
HP models 6030A, 6031A, 6032A, 6035A. and 6038A are stable when operating in CC into inductive loads up to 100 mH, and the HP 6033A and 6038A can handle up to 1 H.  A special modification is available for HP models 6030A, 6031A and 6032A to ensure stable operation when operating into inductive loads up to 10 H.
