Warnings
and
Cautions
Warnings and cautions are defined and formatted in this manual as shown below.
Power
Supply
Safety
WARNING
Describes a potential hazard which could result in injury or death, or, a procedure
which, if not performed correctly, could result in injury or death.
!
CAUTION
Describes a procedure which, if not performed correctly, could result in damage
to data, equipment, or systems.
WARNING—High Energy and High Voltage
Exercise caution when using and calibrating a power supply. High energy levels
can be stored at the output voltage terminals on a power supply in normal
operation. In addition, potentially lethal voltages exist in the power circuit and on
the output and sense connectors of a power supply with a rated output greater
than 40 V. Filter capacitors store potentially dangerous energy for some time after
power is removed.
!
CAUTION
Operate the power supply in an environment free of flammable gases or fumes. To
ensure that the power supply’s safety features are not compromised, use the
power supply as specified in this manual and do not substitute parts or make any
unauthorized modifications. Contact the service technician for service and repair
help. Repairs must be made by experienced service technicians only.
!
CAUTION
For Use as a Battery Charger
When you are using any of these power supplies for battery charging applications,
it is essential to provide an appropriately sized fuse or circuit breaker in series
between the power supply output and the battery.
Installation of a protector (fuse or DC circuit breaker) rated for about 115% of the
maximum current rating of the power supply and designed specifically to interrupt
the DC voltage of the battery, will provide adequate reverse polarity current
protection. Where several power supplies are in parallel, it is best to fuse each one,
rather than one large fuse for all.

Section 1. Features and Specifications
Introduction
The HPD Series of DC power supplies provides highly stable, variable output
voltage and current for a broad range of development and system requirements.
These units employ high frequency switching regulator technology to achieve high
power density and small package size, as well as a linear post-regulator circuit for
low output noise and fast response. A wide variety of options is available, including
both analog and IEEE-488 controlled programming, to make this series the first
choice in flexible power system design.
Table 1.1 300 Watt Series Models
Features
• High frequency switching technology allows high power density, providing
increased power output in a small, light, package.
• The power supply delivers simultaneous digital displays for both voltage and
current, and bar graph displays for monitoring transient changes, which gives the
user the benefit of continuous, up-to-date information.
• Ten-turn voltage control permits high resolution setting of the output voltage.
• Current limit is fully adjustable from zero to the rated output with a single turn
control.
• The automatic crossover system allows the power supply to automatically
switch operating modes into current or voltage mode.
• Impedance-switched remote sensing lets operators display the voltage at the load
with no switch ambiguity.
• Multiple units can be connected in parallel or series to produce greater diversity.
• Short-circuit-proof power outlets give greater operating safety.
• These power supplies (available in single and dual outputs) can be combined
with one or more 60 watt series power supplies to create mixed units that are
ideal for high precision applications.
