Introduction
Overview
Chapter 1 contains important information you should read BEFORE attempting to
install and power-up your APS-1000 Series Power Converter. The information in this
chapter is provided for use by experienced operators. Experienced operators
understand the necessity of becoming familiar with, and then observing, life-critical
safety and installation issues. Topics in this chapter include:
Safety Notices
Warnings
Cautions
Preparation for Installation
Installation Instructions
Transportation
Storage
Introduction to the APS-1000 Power Converter
APS-1000 Series Power Converters have been designed for long-life trouble-free
operation in the shop-floor testing environment. The input to APS-1000 units is
commercially available power at fixed voltage and frequency. The output from APS-
1000 units is programmable power at user-controlled voltages and frequencies.
There are several operational modes: (1) front panel manual control; (2) manually
programmed test sequences; (3) external control of the manually programmed
instruction test sequences.

CHAPTER 1

APS-1000 Series 1 - 2 OM-001-01000-000-04.0
The APS-1000 Series of Power Converters have been designed to provide frequency
and voltage conversion in a controlled test environment. Both manually adjustable and
remotely-programmable settings are provided. All APS-1000 Series Power Converters
provide 1-phase output power. Different models cover the power range from 2 kVA to
60 kVA. All units provide user-controlled 1-phase output power within the frequency
range of 45 – 500 Hz.
All APS-1000 Series units operate as double-conversion power converters. The first
conversion is AC to DC. The second conversion is DC back to AC. Three units (APS-
1002, APS-1003, and APS-1005) operate with 1-phase input power. All other units
operate with 3-phase input power. After rectification, filtering removes high-frequency
content. Low-ripple DC is subsequently converted to 1-phase AC by a high-frequency
pulse-width-modulated (PWM) switcher. Precise control is maintained by using a
highly stable digital oscillator.
APS-1000 Series Power Converters are designed for long-term continuous operation
in sheltered (no rain) environments. Because there are no batteries, APS-1000 units
operate reliably over a wide ambient temperature range. Through the use of switching
technology the equipment is efficient (about 85%). Power Converter units are
relatively tolerant of high dust environments.
Safety Notices
APS-1000 Series Power Converters can transfer very large amounts of
electrical energy very quickly.
The rapid transfer of large amounts of electrical energy is fundamental to any
high-performance power source.
Only experienced operators who have both read and understood the
information in this manual should attempt to operate the unit.
The following warnings and cautions herein must be observed at all times.

Installation Instructions
Input and Output Circuit Breakers
APS-1000 Power Converter input and output circuit breakers and their connections are
on the rear of the unit. Please check to make sure all wires are connected correctly and
secured. Cooling fans, located at the sides and rear of the unit, provide air circulation
for cooling and heat removal.
A typical wiring diagram is shown on the following page.
AC Line Input Current Requirements
TheAC input requirement for the APS Power Converter depends on the configured AC
input voltage and total power level of the specific APS 1000 model. For three phase
AC input models, the current shown in the table below is for each phase.
Input wire sizes must be chosen to support the maximum currents shown in this table
and must conform to local electrical safety codes. Note that these values are based on
the AC input circuit breaker rating for each model. The actual AC input currents are
lower than the values shown.

Chapter 2
Specifications
Overview
Chapter 2 summarizes the capabilities and general features of the APS-1000 family of
Power Converters. Functional capabilities are similar for all units. APS units convert
fixed line voltage at a fixed frequency to user-selected 1-phase output voltages and
frequencies. The primary differences between units are size, weight, type of external
data interface, and specific power handling capability. All units provide built-in PLC
remote control for three program memories.
The Displays and Controls Table in this section provides summary information about
the programmable memories and external control. More detailed information about
external interface control is found in Chapter 5.
This Chapter includes five summary tables and a surge-current performance graph. The
tables summarize different capabilities and features of APS-1000 Power Converters.
The graph illustrates over-current (start-up surge-current) capabilities.
Introduction
APS-1000 Power Converters are rugged versatile workhorses. The intended location
for APS-1000 units is the test floor, not a laboratory workbench. The smallest unit, the
APS-1002, weights 177 lbs. The largest unit, the APS-1060, weighs 1960 lbs. Users
can select from several modes of operation:
full-manual operation
manually programmed operation
remote PLC operation

In keeping with their workhorse nature, all APS-1000 units feature a 200% start-up
surge-current capability. The ability to source initial surge currents prevents the
programmed over-current protection from disabling a test.

Power versus Output Frequency Rating Chart
The following thermal ratings apply to models 1020, 1030 and 1040 as a function of
load and programmed output frequency at an ambient temperature of 25°C. This
derating is caused by heat build-up in the output transformer.
Output load ratings expressed as restive load reflecting % of full load for frequency
ranges at which the power source can operate continuously are as follows:
45Hz ~ 100Hz 90% resistive load
< 200Hz 77% resistive load
< 300Hz 65% resistor load
< 400Hz 52% resistor load
< 500Hz 40% resistor load
At an output frequency of 500Hz and output power into 70% resistor load, the power
source can operate for a period of 15 minutes then instrument output will shut down
because output transformer is too hot.
