Important Safety Instructions
Before applying power to the system, verify that your product is configured properly for your
particular application.
WARNIN
G
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.
WARNIN
G
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.

DESCRIPTION OF EQUIPMENT
1.1 PURPOSE AND CAPABILITIES
The Sorensen DHP Series power supplies are general purpose power supplies designed
specifically for laboratory test and systems applications requiring variable DC sources
with good ripple and regulation characteristics. The DHP power supplies include three
separate series: the 2U High, the 3U High and the 6U High. The power supplies of each
series are constant current/constant voltage supplies with an automatic crossover
feature. The 2U High Series models provide up to 3000 watts, the 3U High models up to
15 kilowatts, and the 6U High models up to 30 kilowatts, each over a wide range of
voltage and current levels.
1.2 TECHNICAL CHARACTERISTICS
The physical, electrical, and environmental characteristics for the 2U, 3U and 6U High
Series are listed in Tables 1-1 through 1-3.

INSTALLATION
2.1 INSPECTION
Inspect the shipping carton for possible damage before unpacking the unit. Carefully
unpack the equipment. Save all packing materials until inspection is complete. Verify
that all items listed on the packing slips have been received. Visually inspect all exterior
surfaces for broken knobs, connectors, or meters. Inspect for dented or damaged
exterior surfaces. External damage may be an indication of internal damage. If any
damage is evident, immediately contact the carrier that delivered the unit and submit a
damage report. Failure to do so could invalidate future claims.
2.2 INPUT/OUTPUT CONNECTORS
Tables 2-1 and 2-2 list all external connections for the 2U, 3U and 6U High Series
models, respectively. Tables 2-3 and 2-4 provide input and output connector
descriptions.
For permanently connected equipment, a readily accessible disconnect device shall be
incorporated in the fixed wiring. For plugable equipment, the socket outlet shall be
installed near the equipment and shall be easily accessible.
Take precautions to ensure that the concentration of ozone is limited to a safe value.
The recommended long-term exposure limit for ozone is 0.1 PPM (0.2 mg/m3).
NOTICE
For proper connection to the mains, a
100 amp or less circuit breaker or fuse
is required.
2.3 LOCATION AND MOUNTING
The DHP Series models are intended for mounting in a standard 19.0-inch equipment
rack. Four screws, two on each side of the front panel, should be used to secure the
unit in place. NOTICE
The unit should be provided with
proper ventilation. The top, rear and
both sides of the unit should be free of
obstructions.
