Safety Guidelines
General
Guideline
CAUTION
Do not place any heavy object on the ASD-1150.
Avoid severe impact or rough handling that
leads to damaging the ASD-1150.
Do not discharge static electricity to the ASD-
1150.
Use only mating connectors, not bare wires, for
the terminals.
Do not block the cooling fan opening.
Do not disassemble the ASD-1150 unless you
are qualified.
(Measurement categories) EN61010-1:2010 and EN61010-2-030
specifies the measurement categories and their requirements as
follows. The ASD-1150 falls under category II.
Measurement category IV is for measurement performed at the
source of low-voltage installation.
Measurement category III is for measurement performed in the
building installation.
Measurement category II is for measurement performed on the
circuits directly connected to the low voltage installation.
0 is for measurements performed on circuits not directly
connected to Mains.
Power Supply
WARNING
AC Input voltage range: 85Vac~265Vac
Frequency: 47Hz to 63Hz
To avoid electrical shock connect the protective
grounding conductor of the AC power cord to
an earth ground.
Cleaning the
ASD-1150
Disconnect the power cord before cleaning.
Use a soft cloth dampened in a solution of mild
detergent and water. Do not spray any liquid.
Do not use chemicals containing harsh material
such as benzene, toluene, xylene, and acetone.

SAFETY INSTRUCTIONS

Operation
Environment
Location: Indoor, no direct sunlight, dust free,
almost non-conductive pollution (Note below)
Relative Humidity: 20%~ 85% (no condensation)
Altitude: < 2000m
Temperature: 0°C to 50°C
(Pollution Degree) EN61010-1:2010 and EN61010-2-030 specifies
the pollution degrees and their requirements as follows. The ASD-
1150 falls under degree 2.
Pollution refers to “addition of foreign matter, solid, liquid, or
gaseous (ionized gases), that may produce a reduction of dielectric
strength or surface resistivity”.
Pollution degree 1: No pollution or only dry, non-conductive
pollution occurs. The pollution has no influence.
Pollution degree 2: Normally only non-conductive pollution
occurs. Occasionally, however, a temporary conductivity caused
by condensation must be expected.
Pollution degree 3: Conductive pollution occurs, or dry, non-
conductive pollution occurs which becomes conductive due to
condensation which is expected. In such conditions, equipment
is normally protected against exposure to direct sunlight,
precipitation, and full wind pressure, but neither temperature
nor humidity is controlled.
Storage
environment
Location: Indoor
Temperature: -25°C to 70°C
Relative Humidity: ≤90%(no condensation)
Disposal
Do not dispose this instrument as unsorted
municipal waste. Please use a separate collection
facility or contact the supplier from which this
instrument was purchased. Please make sure
discarded electrical waste is properly recycled to
reduce environmental impact.

Power cord for the United Kingdom
When using the power supply in the United Kingdom, make sure
the power cord meets the following safety instructions.
NOTE: This lead/appliance must only be wired by competent persons
WARNING: THIS APPLIANCE MUST BE EARTHED
IMPORTANT: The wires in this lead are coloured in accordance with the
following code:
Green/ Yellow:
Earth
Blue:
Neutral
Brown:
Live (Phase)
As the colours of the wires in main leads may not correspond with
the coloured marking identified in your plug/appliance, proceed
as follows:
The wire which is coloured Green & Yellow must be connected to
the Earth terminal marked with either the letter E, the earth symbol
or coloured Green/Green & Yellow.
The wire which is coloured Blue must be connected to the terminal
which is marked with the letter N or coloured Blue or Black.
The wire which is coloured Brown must be connected to the
terminal marked with the letter L or P or coloured Brown or Red.
If in doubt, consult the instructions provided with the equipment
or contact the supplier.
This cable/appliance should be protected by a suitably rated and
approved HBC mains fuse: refer to the rating information on the
equipment and/or user instructions for details. As a guide, a cable
of 0.75mm2should be protected by a 3A or 5A fuse. Larger
conductors would normally require 13A types, depending on the
connection method used.
Any exposed wiring from a cable, plug or connection that is
engaged in a live socket is extremely hazardous. If a cable or plug is
deemed hazardous, turn off the mains power and remove the cable,
any fuses and fuse assemblies. All hazardous wiring must be
immediately destroyed and replaced in accordance to the above
standard.

GETTING STARTED
This manual describes the specifications,
installation and operation instructions of GW
Instek ASD-1150 programmable AC/DC Power
Source. In this manual the term, AC/DC Source,
stands for GW Instek ASD-1150 programmable
AC/DC Source.
The AC source is a high efficiency programmable
AC power source, which provides low distortion
sinusoid AC voltage output and measurement.
Stable voltage and frequency are obtained
through accurate digital calculation provided by
DSP IC. Remote programming is accomplished
either by the GPIB bus or the RS-232C serial port.

Preparation for Use
Before start using, the instrument must be connected with an
appropriate AC line input. As the instrument is cooled by fans, it
must be installed in an area with sufficient space for air circulation.
It should be used in an area where the environment temperature
does not exceed 40°C.

Input Connection
The input terminal block is located on the instrument rear panel.
The temperature rating of the power cord must be rated at least for
85°C. The current rating of input power line must be greater than
or equal to the maximum current rating of the AC source.
To put a 30A breaker (ABT A) (30A breaker (ABT B)) at AC input
side.
See figures below and do the following steps one by one:
Steps
1. Remove the safety cover at the back side of AC
source.
2. Connect the AC lines to the terminal blocks of
the AC source.
3. Make sure the removable safety cover does
fully cover the AC input terminal.
4. Turn off AC power supply to AC source or
make safety isolation before installing or taking
off external terminal with hazard voltages.

Caution
To protect operators the wire connected to the GND
terminal must be connected to the ground. Under no
circumstances shall this AC source be operated
without an adequate ground connection.
Installation of the AC input power cord must be done by
professional personnel in accordance with local electrical codes.

ASD-1150 User Manual

Output Connection
The output terminal block is located at the rear of the AC source.
Load connecting to the “N” and “L” is done at the output terminals.
To meet the safety requirements, the safety cover must be fastened.
The wires to the load must be sufficiently large gauges, so they will
not overheat while carrying the output current. For most users, if
the current for product under test is not high, there is one outlet
with 10 amperes rating at front panel can be used.
Remote Sense Connection
The AC source remote sense function monitors the load terminal
voltage instead of the AC source output terminal. It ensures the
delivery of accurate voltage as programmed at the load by
compensating the output voltage drop over the connecting cable
automatically. You have to set Remote Sense ON so as to enable
this function.
Connect the sensing wires from “Ls” and “Ns” terminals to the
load as shown in figure below. As the sensing wires carry only a
few milli-amperes, the wire gauges are much smaller than the load
cables. The sensing wires are part of the feedback path of the AC
source. They must be kept at a low resistance in order to maintain
the best performance. Connect the sensing wires carefully so that
they will not be open-circuited. If the sensing wires are left
unconnected or become open-circuited during operation, the AC
source will disable the output. The sensing wires must be a twisted
pair to minimize the pickup of external noise. The sensing wires
need to be connected as close to the load input terminal as possible.
