Safety Precautions
To ensure safe use, be sure to observe the following warnings and cautions.
GW Instek shall not be held liable for damages that arise from a failure to observe these warnings and
cautions.
This product is a Class 1 product (with protective conductor terminal) that conforms to the JIS and IEC
insulation standards.
Be sure to observe the contents of this instruction manual.
This instruction manual contains information for the safe operation and use of this product.
Be sure to read this information first before using this product.
All the warnings in the instruction manual must be heeded to prevent hazards that may cause major
accidents.
Be sure to ground the product.
This product uses a line filter and must be grounded to avoid the risk of electric shock.
To prevent electric shock, be sure to safely implement grounding according to Japanese Standard
for Electrical Equipment Technology D (100 or lower) or higher.
The APS-1102A is automatically grounded when the 3-prong power plug is connected to a 3-prong
power outlet with a protective grounding contact.
This product does not come with a 3-prong to 2-prong conversion adapter. When using a separately
sold 3-prong to 2-prong conversion adapter, be sure to connect the grounding wire of the adapter to
the grounding terminal next to the outlet.
Check the power supply voltage.
This product operates on the power supply voltage indicated in Grounding and Power Supply
Connection in this instruction manual.
Prior to connecting the power supply, check that the voltage of the power supply matches the rated
power supply of the product.
In case of suspected anomaly
If this product emits smoke, an abnormal smell, or abnormal noise, immediately power it off and
stop using it.
If such an anomaly occurs, do not use this product until it has been repaired, and immediately report
the problem to the location of purchase (either GW Instek or our agent).
Do not use this product when gas is present.
An explosion or other such hazard may result.
Do not remove the cover.
This product contains high-voltage parts. Absolutely never remove its cover.
Even when the inside of this product needs to be inspected, do not touch the inside. All such
inspections are to be performed by service technicians designated by GW Instek.
Do not modify this product.
Absolutely never modify this product, as this may cause new hazards and may disqualify this
product from repair in case of failure.

Before operating the device, be sure to safely implement grounding
according to Japanese Standard for Electrical Equipment Technology D
(Type 3, 100 Ω or lower) or higher.
Warning Symbol
This symbol indicates information for avoiding danger to human life or bodily
injury while handling this product.
Caution Symbol
This symbol indicates information for preventing damage to the product
when handling it.
Other symbols
This symbol indicates the “on” position of the power switch.
This symbol indicates the “off” position of the power switch.
This symbol indicates that the external conductor of the connector is connected to
the case.
This symbol indicates that the external conductor of the connector is connected to
the signal ground.

1.1 General
The APS-1102A programmable AC/DC power source is a power source that can output AC and DC
power, features a compact design for convenient desktop use, and provides a wealth of measurement
functions.
Rated output voltage is 100 Varmus (100 V range) or 200 Vrms (200 V range), with maximum output
capacity of 1 kVA (during AC 200 V input).
It also features eight output modes, with DC output, external input amplification, and line-synchronized
output.
The APS-1102A can be controlled remotely from an external computer via USB or RS232 interface. The
accompanying software supports use of the following functions.
Panel operations
Sequence editing and execution
Arbitrary waveform editing and transfer
Data logger (by capturing measured values)
Worldwide power supply input is supported. Input power factor control function minimizes power supply
input current.
1.2 Features
Control panel with large LCD screen
Settings and measured values are displayed on a large, easy-to-read backlit screen.
Various output modes
Output modes include two operation modes: alternate current (AC) and direct current (AC+DC), each
of which can be combined with four signal source modes: internal (INT), external (EXT), internal +
external (ADD), and external synchronization (SYNC) for a total of eight modes. In the AC mode, DC
component is removed.
Various measurement functions
The APS-1102A is equipped with the following measurement functions.
Voltage (RMS value, average DC value, peak value)
Current (RMS value, average DC value, peak value, peak hold value)
Power (effective, reactive, apparent)
Frequency (only in the external synchronization mode)
Load power factor
Load crest factor
APS-1102A
1 OVERVIEW
1-3
Harmonic current (up to 40th harmonic, 50 Hz/60 Hz fundamental only)
Note: This measurement does not conform to the IEC or other standard.
Enables AC-superimposed DC output
When in the AC+DC mode, an AC wave (sine wave, square wave, or arbitrary waveform) can be
superimposed on the DC output.
Also supports capacitor input load (up to crest factor 4 is supported)
Enables peak current output of up to four times as large as the maximum current (RMS value).
Can be used as an external input amplifier
When “internal + external” is selected, an internal signal source can be added to the external signal
input.
Sequence function
When using an internal signal source, output parameters (output voltage, output frequency, etc.) can be
successively and rapidly changed or swept. In addition, output of specified patterns can be provided
by program in advance.
Output current limiter function, voltage and frequency upper limit and lower limit
setting functions
The output current is limited within the maximum values that have been set independently for positive
and negative. As for the output voltage and the output frequency, their setting ranges can be
adjustable.
USB interface (USBTMC), RS232 interface are standard equipped
USB interface and RS232 interface are provided for external control, such as from a personal
computer.
Output outlets equipped on front panel (universal type)
Various types of power plugs from around the world can be connected.
Supports worldwide range input power line voltages
Input power factor control (PFC) function for 90 V AC to 250 V AC helps minimize input power line
current.
