Operation Procedure
1. Stand Alone Operation
Press and hold this button will show the output voltage and current
limiting values previously set at the selected range even the output
terminal is off.
Check the power supply is set as Stand Alone operation mode with the
Master & Slave switch (17) set to Master position. All controls function
just like a normal power supply.
4. Setting the Current Limiting Value
Switch on the power supply without any load by pushing (1) and the
LED display should light up. There should not be any reading on the
voltmeter and the ammeter.
You can set the current limiting value without connecting to the load or
shorting the output terminal. Press and hold the PREVIEW button (7)
and turn the current volume (5) to our desired value.
5. UVL/VOLTAGE button (6) and UVL LED (10)
Press the Output On-Off button (9) and its green LED will light up, the
voltmeter should show the set output voltage.
Take note of the preset range and its LED, turn the voltage volume to
check on the voltmeter reading at the same time.
2. Selection of Voltage and Current Range at (8)
When change to other Voltage and Current range setting (8), take note
of the Voltmeter reading changing to zero voltage and LED of Output
On-Off button (9) going off.
The output terminal is off automatically when the VI range is changed,
this is to safeguard the connected load.
3. PREVIEW button
Press (7) to check the values of VI when output terminal is off.
Press UVL/VOLTAGE button to see the default value of Upper Voltage
Limit. The LED (10) also lights up during this operation.
6. Setting the Upper Voltage Limit UVL value
Press button (6) and insert a small screw driver less than 3mm
diameter into (3), slowly turn to clockwise to increase and anticlockwise to decrease the UVL value .
The UVL is an added protection for voltage sensitive load, only one
UVL value can be set for all three ranges. When the output voltage
exceeds the set UVL, the output terminal will be off automatically and
the ALM (13) LED is light up at the same time.
7. Master & Slave Operation
7.1 Introduction
Two or more units of PeakTech 6110 can be connected in parallel to
increase output current to the sum of connected power supplies. In this
mode of operation, the designated Master power supply will control all
the settings in voltage and current of the Slave power supplies.
Preparation and connecting the Control Terminals (19)
Make sure all the power supplies are set to the same UVL by(6) and
the same VI Range by (8).
Set the voltage and current limit of all the Slave units to maximum
Switch off all power supplies for connection.
Set the switch (17) to Slave position of all the Slave power supplies.
Connect the Master & Slave control circuit as shown in Fig 8.1 and Fig

You can either use the Output Terminals at the front (2) or at the back
(20) to connect to the load as shown in Fig 8.3 depending on your
application condition and requirement.
For proper performance, all power cables should be of the same
thickness and length.
Double check the maximum voltage and current setting of the Slave
Switch on the Master unit first and set to desired voltage, then switch
on the Slave units.

You can set the current limiting value without any connected load or
shorting the output terminal.

confirmation of correct connections.
All the output voltages and currents of the Slave units are now
controlled by the Master Unit.
Remarks :
When the output current in the Master & Slave connection drops to
zero ampere, the output voltage will no longer be controlled by the
Master unit. Make sure to keep a minimum current flowing that is at
least several percent of the rated current at all times. This can be done
by supplying a small removable load.

8. Remote Sensing Operation
When the output current is large or long connection to load , there is a
voltage drop across the connecting cable such that the voltage at load
point is less than at the output terminal of the power supply.
By making an extra connection from the remote sensing terminal (19)
to the load point ( Attention do not reverse polarity ) will make up for
the load line voltage drop and make the voltage at the load point and
output terminal the same. ( Make sure to disconnect the wiring to
remote sensing first before disconnecting the main output connection ).
