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.

1. Introduction
This instruction manual contains information on the installation, operation, calibration and
maintenance of all power systems that use the CSW5550.
This user manual also covers higher power configurations consisting of multiple units of the
CSW5550 operated in parallel. Such models are the CSW11100, CSW16650, CSW22200,
CSW27750, CSW33300, CSW38850 and CSW44400.
Figure 1-1 California Instruments CSW5550 (With Rack Mount Ears)
1.1 General Description
The CSW5550 is a high efficiency, lightweight AC power source that provides a precise output
with low distortion. The CSW Series offers a 0-156/0-312 AC or DC voltage range. Full power
is available from 115/230V to full-scale voltage using a constant power mode of operation.
Two to eight CSW5550 units can be connected in parallel as a single-phase or 3-phase power
system for an output of up to 44.4 KVA. They can be operated with AC or DC output.
The CSW5550 Series also offers AC+DC output mode.
Remote Interfaces
The CSW5550 has the standard GPIB, RS232 and USB remote interfaces. The LAN (Ethernet)
interface is offered as an option. With the LAN interface the RS232 interface will not be
functional.

XLOAD The CSW5550 is guaranteed to be stable for power factors from 0 leading to 0
lagging. The most difficult load for most amplifiers is driving large capacitive
loads (10-10,000F).Though stable with its normal loop compensation, the
CSW can provide additional phase/gain margin with these unusual loads by
selecting XLOAD On. This significantly improves the transient response of the
amplifier.
X-Load should only be used for reactive loads, and with programmed
frequencies of less than 1000 Hz.
Output current for which specifications apply is de-rated for frequencies above 400Hz as a function of
voltage, and for maximum power of 1850 VA per phase, as shown in Figure 2-1 and Figure 2-2.
