1 Safety precautions
• Do not operate under Lightning conditions
• Do not keep in wet areas
• Always adjust required voltage/current, before
connecting the power lines to the DUT
2 Device overview
PS1010 is a PWM controlled highly power efficient
digital power supply. The features extend to;
• Voltage controllability
• Current controllability
• Measuring voltage at any point in the
device/circuit under test while powered from the
PS1010-3A
• Measuring voltage at any out side source such as
a battery or any other voltage point
• Display capability of any of the followings
o Out put voltage
o Actual current flow
o SET Current limit
o Voltage as a voltmeter
o Firmware version/Error codes

5 Device operation
5.1 Setting output voltage
• Put VM/Vout switch [(10)] to Vout position
• Put C/V switch [(8)] to V position
• Volt LED indicator will light up [(4)]
• [(3)] will display “U” for Volt
• Adjust the voltage controller [(5)] to get the
required value.
• The value will be displayed on [(2)] with one
decimal place
Note: Make sure to keep reasonable current limiting
value before setting output voltage so that current
control (CC) will not take over.
5.2 Setting current limit
• Press and hold C-SET button [(7)].
• Then display[(2)] will show the present current
limit in Amperes.
• [(3)] will display “A” for Current
• Now rotate the current controller knob [(6)]
while looking at the display. Stop when the
desired value appears.
Note: The output voltage will be automatically be
controlled if the external device tries to drag current
more than the set limit.
5.3 Viewing actual current flow
• Power up the DUT with PS1010-3A

• Put VM/Vout switch [(10)] to Vout position
• Put C/V switch [(8)] to C position
• Amp LED indicator will light up [(4)]
• [(3)] will display “A” for Ampere
• Actual current value will be displayed on [(2)]
with two decimal places
5.4 Voltmeter mode
5.4.1 Measuring voltage at various
positions while powered from the
PS1010-3A
• Set required output voltage and power up the
DUT
• Put VM/Vout switch [(10)] to VM position. VM
LED indicator [(4)] will light up.
• Test voltage values using the VM probe [(11)].
The voltage values are displayed relative to the
GND pin of the Vout terminal [(9)].
Note: the user can select various switch positions at
any time to see the Current limit, Actual current
flow, voltage at output terminals or at VM without
disrupting the power at the output terminals.

5.4.2 Measuring voltages at external
sources
• Put VM/Vout switch [(10)] to VM position. VM
LED indicator [(4)] will light up
• Connect wires as shown below(VM terminal and
the GND of Vout terminals)
• Value will be displayed [(2)].
5.5 Viewing firmware version
• Switch OFF the PS1010 [(1)]
• Put VM/Vout switch [(10)] to VM position
• Press and hold the C-SET button

• Switch ON the PS1010-3A [(1)]
• [(3)] will show “F” to indicate Firmware version
• Display [(2)] will show the Firmware version in
the following order.
6. 0. 1 F
Major version

Minor version
Note: PS1010-3A is not firmware upgradeable by
the customer.
6 Troubleshooting
No display
• Check power cable/Input power
• Check power switch [(1)]
• Check fuse at the back of the PS1010
Even if the voltage adjust knob is turned the value
does not vary.
• Check whether the Volt LED indicator [(4)] is
ON. If not then you are not in the right set up
and follow up on how to setting the output
voltage guide lines
• Check whether the CC LED indicator [(4)] is
ON. If so then the current limiting occurs due to
insufficient current limit adjustment or due to
excessive current draw.

PS1010 is in its current mode and the Amp indicator
is also ON. But rotating current controller knob does
not affect the display value.
• You are at the current mode and at this mode the
display shows only the actual current draw by
the DUT. But rotating the current controller knob
means changing the Max current limit. To see
the max current limit, C-SET button should be
pressed.
Cannot increase voltage from a certain value.
• Check whether CC indicator appears. If so,
increase the current limit.
7 General information
Terminology
DUT- Device Under Test
