ASR-2000 Series User Manual
Do not dispose electronic equipment as unsorted
municipal waste. Please use a separate collection
facility or contact the supplier from which this
instrument was purchased.
General
Guideline
CAUTION
Do not place any heavy object on the ASR-2000.
Avoid severe impact or rough handling that
leads to damaging the ASR-2000.
Do not discharge static electricity to the ASR-
2000.
Use only mating connectors, not bare wires, for
the terminals.
Do not block the cooling fan opening.
Do not disassemble the ASR-2000 unless you are
qualified.
If the equipment is used in a manner not
specified by the manufacturer, the protection
provided by the equipment may be impaired.
(Measurement categories) EN 61010-1:2010 specifies the
measurement categories and their requirements as follows. The
ASR-2000 doesn’t fall under category II, III or IV.
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.

SAFETY INSTRUCTIONS
Power Supply
WARNING
AC Input voltage range:
100 ~ 240 Vac
Frequency: 47 ~ 63 Hz
To avoid electrical shock connect the protective
grounding conductor of the AC power cord to
an earth ground.
The power switch that is included in the
instrument is not considered a disconnecting
device.
The power cord set is used as the disconnecting
device and shall remain readily operable.
Do not position the equipment so that it is
difficult to operate the disconnecting device.
Do not replace the power supply cord with an
improperly rated cord. A certified power supply
cord should not lighter than light PVC sheathed
flexible cord according to IEC 60227,
designation H05VV-F, and be rated for at least
3G 0.75 mm² (for rated current up to 10 A) or 3G
1.0mm² (for rated current over 10 A up to 16 A)
wire or larger, and the length of the cord that
does not exceed 2 m must be used.
Cleaning the ASR2000
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.
Operation
Environment
Location: Indoor, no direct sunlight, dust free,
almost non-conductive pollution (Note below)
Relative Humidity: 20%~ 80%, no condensation
Altitude: < 2000m
Temperature: 0°C to 40°C

ASR-2000 Series User Manual
(Pollution Degree) EN 61010-1:2010 specifies the pollution degrees
and their requirements as follows. The ASR-2000 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

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.

GETTING STARTED
Inrush Current
When the power supply switch is first turned
on, an inrush current is generated. Ensure there
is enough power available for the power supply
when first turned on, especially if a number of
units are turned on at the same time.
Capacitive Load
When the power supply connects to a capacitive
load, e.g., capacitor, the load is being charged
consecutively and the larger the voltage change,
the more the current grow. Also, the overshoot will
be possibly generated within the currents output,
therefore leading to output turned off thanks to
overcurrent protection from the power supply.
It is suggested to lower down the set voltage
output from power supply so that the voltage of
capacitive load decreases per certain unit time. In
addition, a block diode is necessary to keep
current from flowing back to the output terminal
of power supply. Refer to the figure below where a
block diode connects with the capacitive load in
series to efficiently prevent current from flowing
back to the power supply.

Considerations

29
ASR-2000 Series User Manual
Inductive Load
When the power supply connects to an inductive
load, e.g., inductor, which generates a back EMF
(Electromotive Force) when output current is
accidentally turned off, a backflow diode is
necessary for absorbing the back EMF, which may
cause irreversible damage to the power supply.
Refer to the following figure where a backflow diode
connects with the inductive load in parallel to
effectively absorb the possible back EMF.
