Introduction
This 80W Constant Power lab. grade power supply has an automatic range of 0.5-36V and 0-5A.
The max. limits of current & voltage are calculated by Imax x Vmax = 80W. So at 36V its maximum current
is 80W/ 36V = 2.2A , the max. voltage at 5A = 80W/ 5 = 16V. Its operation voltage and current spectrum is
larger than 3 conventional power supplies of the same power rating.
Adjustable upper voltage and current limits are necessary functions to protect sensitive devices against the
wide swing of output current or voltage available.
3 user presets of V&I for frequently used output settings.
Master & Slave configuration with either SSP-9080 or SSP-9081 as Master for parallel connection of up to
30 Units of either SSP-9080 or SSP-9081as slave units.
When SSP-9081 is set as Master, all the special functions e.g. remote program, dc ramp waveform
generator and Ethernet connectivity are operational with the increase of current output from SSP-9080 slave
units.

Master/Slave configuration
The SSP-9080 and SSP-9081 can be configured for Master/Slave connection either with the same model or
in combination of both models.
Every slave unit should be assigned an uniqueAddress ID from 1-30. The Master unit must be assigned an
Address ID=0 (factory default)
The load current is shared equally by all units and the Masterʼs output voltage is the output voltage of all
units. All the functions of the Master supply can be utilized.
Example: one SSP-9081 as Master and 3 SSP-9080 Slave units, the maximum combined output current is
20 Amp and functions of SSP-9081 are usable.
Wiring of master and slave units
·Make sure that the output cables from each power supply must be of the same length and thickness.
You can use power distribution block from car audio shop to tidy up the wiring.
·Always double check if the terminator plug is installed at the last slave unit.
·Look for the SLAVE GREEN LED which lights up to indicate that Master & Slave connection is correct.
·The full Master & Slave operation begins when output cables are connected to the load and the Master
output is switched to ON.
·The current reading on the Master Unit Xthe total number of units connected = Total Current to the
Load.
Steps for Changing the addressID,
·Press and hold button to enter setting menu.
·Rotate VOLT. knob to select address menu. The display shows
·Press VOLT. knob to enter address menu.
·Rotate CURR knob to change address ID.
·Press VOLT. knob to confirm.
·Press to exit menu.

Remote sensing operation
When the output current is large or long cable to load, there is a voltage drop across the connecting cable
such that the voltage at the load point is less than at the output terminal of the power supply. By connecting
the Remote Sense terminals to the load point, the voltage reading at the output display and the voltage at
the load point will be the same.
Connecting remote sensing
·Connect the power supply output terminals to the load (use the front or rear O/P terminals)
·Connect the Remote Sensing terminals to the Load
·Connect RS+ to the Positive (+) connection at the load
·Connect RS- to the Negative (-) connection at the load
Factory reset
The Factory reset feature is reset the Preset program, UVL, UCL to factory default setting.
Steps for Factory reset
·Press and hold button to enter setting menu.
·Rotate VOLT. knob to select factory reset menu. The display shows
·Press VOLT. knob to enter address menu. The display shows
·Rotate CURR knob to change from to
·Press CURR. knob to reset unit.
The power will reset immediately.

of UCL which is less than the output current set value.
e.g. Set Output Voltage is 15V. Set UVL to 12V, this
error message comes out.
Solution 1 - Rotate Volt knob clockwise.
Both UVL and Output will be setto new
UVL setting 12Vas in the example.
Solution 2 - Reset Unit byOff &On Power
Switch same result as Solution 1.
UCL (Upper CurrentLimit) setting error.
This error message indicate thatyou tryto seta value
of UCL which is less than the output current set value.
