Introduction
Overview
Chapter 1 contains important information you should read BEFORE attempting to
install and power-up your APS-1000P SeriesPower 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

Introduction to the APS-1000P Power Converter
APS-1000P Series Power Converters have been designed for long-life trouble-free
operation in the shop-floor testing environment. The input to APS-1000P units is
commercially available power at fixed voltage and frequency. The output from APS-
1000P 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 test
sequences; and (4) external programmable control. All units have the ability to be
externally controlled by remote switch closures. For more complex control sequences

and data acquisition, each P-series unitincludes auser-specified RS-232external serial
interface or GPIB external parallel interface.
The APS-1000P Series of Power Converters have been designed to provide frequency
and voltage conversion in a controlledtest environment. Both manually adjustable and
remotely programmable settings are provided. All APS-1000P Series Power
Converters provide 1-phase output power. Different models cover the power range
from 2 kVA to 60 kVA. All units provideuser-controlled 1-phase output powerwithin
the frequency range of 45 –500 Hz.
All APS-1000P Series units operate as double-conversion power converters. The first
conversion is AC to DC. The second conversion is DC back to AC. All units (except
the 1-phase input APS-1002P, APS-1003P, and APS-1005P) 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-1000P Series Power Converters are designed for long-term continuous operation
in sheltered (no rain) environments. Because there are no batteries, APS-1000P 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-1000P 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.

Chapter 2
Specifications
Overview
Chapter 2 summarizes the capabilities and general features of the APS-1000P family
ofPowerConverters. Functional capabilities aresimilar 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.
At the time of purchase, APS-1000P users select between one of two external control
and data interfaces: either RS-232 or GPIB. Both external interfaces provide full input
and output control of functions anddata, independent of internally stored programs. In
addition, the external interfaces control eight APS-1000P internal program memories.
Please note, application of external control and data acquisition require instrumentation
programming skills. Therefore, Adaptive Power Systems recommends that only
experienced test instrumentation programmers prepare the RS-232 or GPIB test
programs.
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.

APS-1000P Series Operation Manual 2 - 2 OM-001-01000-00P-04.0
Introduction
APS-1000P Power Converters are rugged versatile workhorses. The intended location
for APS-1000P units is the test floor, not a laboratory workbench. The smallest unit,
the APS-1002P, weights 177 lbs. The largest unit, the APS-1060P, weighs 1825 lbs.
Users can select from several modes of operation:
full-manual operation
manually programmed operation
remote PLC operation
remotely programmed serial data operation (RS-232 option)
remotely programmed parallel data operation (GPIB option)
combinations of these operational modes
In keeping with their workhorse nature, all APS-1000P 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 applyto 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 frequencyof 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.
