ImportantSafetyInstructions
Before applying power to the system, verify that your product is configured properly for your
particular application.
WARNING
Hazardous voltages may be present when covers are removed. Qualified
personnel must use extreme caution when servicing this equipment.
Circuit boards, test points, and output voltages also may be floating above
(below) chassis ground.
WARNING
The equipment used contains ESD sensitive parts. When installing
equipment, follow ESD Safety Procedures. Electrostatic discharges might
cause damage to the equipment.
Only qualified personnel who deal with attendant hazards in power supplies, are allowed to perform
installation and servicing.
Ensure that the AC power line ground is connected properly to the Power Rack input connector or
chassis. Similarly, other power ground lines including those to application and maintenance
equipment must be grounded properly for both personnel and equipment safety.
Always ensure that facility AC input power is de-energized prior to connecting or disconnecting any
cable.
In normal operation, the operator does not have access to hazardous voltages within the chassis.
However, depending on the user’s application configuration, HIGH VOLTAGES HAZARDOUS TO
HUMAN SAFETY may be normally generated on the output terminals. The customer/user must
ensure that the output power lines are labeled properly as to the safety hazards and that any
inadvertent contact with hazardous voltages is eliminated.
Guard against risks of electrical shock during open cover checks by not touching any portion of the
electrical circuits. Even when power is off, capacitors may retain an electrical charge. Use safety
glasses during open cover checks to avoid personal injury by any sudden component failure.
Neither AMETEK Programmable Power Inc., San Diego, California, USA, nor any of the subsidiary
sales organizations can accept any responsibility for personnel, material or inconsequential injury,
loss or damage that results from improper use of the equipment and accessories.

Introduction
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.

Model Output Voltage Output Current
15–20 0–15 V 0–20 A
30–10 0–30 V 0–10 A
60–5 0–60 V 0–5 A
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,andbargraphdisplaysformonitoringtransientchanges,whichgivesthe
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-switchedremotesensingletsoperatorsdisplaythevoltageattheload
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.
