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 ports. 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.

FCC NOTICE
This equipment has been tested and found to comply with the limits for a
Class A digital device, pursuant to part 15 of the FCC Rules. These limits
are designed to provide reasonable protection against harmful interference
when the equipment is operated in a commercial environment.
This equipment generates, uses, and can radiate radio frequency energy
and, if not installed and used in accordance with the instruction manual, may
cause harmful interference to radio communications. Operation of this
equipment in a residential area is likely to cause harmful interference in
which case the user will be required to correct the interference at his own
expense.

ABOUT THIS MANUAL
This manual has been written expressly for the AMREL SPS-A Series of
power supplies that have been designed and certified to meet the Low
Voltage and Electromagnetic Compatibility Directive Requirements of the
European Community.
These models have been designed and tested to meet the Electromagnetic
Compatibility directive (European Council directive 2004/108/EC; generally
referred to as the EMC directive) and to the requirements of the Low Voltage
directive (European Council directive 2006/95/EC, 93/68/EEC, dated 22 July
1993). In addition these models have been found compliant with FCC 47
CFR Part 15, Subpart B 107(e) Class A, 109(g) Class A.
Since the Low Voltage Directive is to ensure the safety of the equipment
operator, universal graphic symbols have been used both on the unit itself
and in this manual to warn the operator of potentially hazardous situations
(see Safety Notice page).

OVERVIEW
1.1 GENERAL DESCRIPTION
The AMREL SPS-A 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. These power supplies are constant current/constant
voltage supplies with an automatic crossover feature.
A variety of user interfaces are available, ranging from manual front–panel
control and standard non–isolated remote analog control, to optional GPIB,
Ethernet or isolated remote analog control.
1.2 SPECIFICATIONS
The following subsections provide environmental, electrical, and physical
characteristics for the SPS-A Series power supplies.
Note: Specifications are subject to change without notice.
Note: The SPS-A Series power supplies are intended for indoor use only. Please
