be connected.

Pay special attention to these two types of notices used in this manual.

Warning

Caution

Operation environmental condition

Warning

Failure to observe this warning may cause injury to persons and damage to power supply or connected

equipment.

1. Do not use this power supply near water.

2. Do not operate or touch this power supply with wet hands.

3. Do not open the casing of the power supply when it is connected to ac mains.

4. Refer all servicing to qualified service personnel only.

5. Before replacing theAC fuse find out and clear up the cause first.

6. Replace theAC fuse with the same type and rating as the original fuse.

Caution

Failure to observe this warning may result in damage to equipment and Improper functioning of the power

supply.

1. Use a grounded 3 pinAC source.

2. This unit is for indoor use only.

3. Do not operate or place this unit in a humid, dusty, in direct sunlight location or near any heat source.

4. Before plugging into local AC mains, check with the rating label at the back of the unit.

5. Do not block any ventilation openings of the unit.

6. This unit must be used within the specified rating, regular excessive continuous overloading may cause

damage to the power supply.

7. The gauge size of input power cable must be at least 0.75 mm² and the total length of power cable must

not exceed 3m.

8. Input Fuse Recommended: T2AL250V (Time-Lag from 2A)

Operating environmental condition

Relative humidity : 10-80%

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.

Display and Indications

Fig. Display panel

4 digitsdisplays

The upper part of display is volt-meter and the lower part of display is amp-meter or watt-meter.

Constant Voltage Mode LED

Indicates the Power Supply is working in Constant Voltage mode.

The output voltage of power supply is kept constant at the set voltage in this mode. The power supply

remains in CV as long as the loading current is lower than the set current limit otherwise power supply will

cross over to CC mode.

Constant Current Mode LED

Indicates the Power Supply is working in Constant Current mode.

When the loading is higher than the set current limit of the set voltage in CV mode, the Constant Current

Mode kicks in. The output current of power supply is kept constant at the set current level provided that the

loading is sufficiently large to draw current equal to or larger than set current, otherwise power supply will

cross over to CV mode.

Watt-meter LED

Indicates the lower row of the 4 digit LED is read as watt-meter. The value is showing output power in Watt.

Amp-meter LED

SSP-9080 User manual

6 / 17

Indicates the lower row of the 4 digit LED is Amp-meter. The value is showing output current inAmpere.

Slave LED

Indicates the Power Supply is in slave mode and controlled by the master unit. The voltage and current

setting of slave units are controlled by the master unit. The buttons and knobs of slave units are locked. The

master unit controls all units. (Details refer to Master & Slave section)

Shift LED

Indicates the Shift key is pressed and the second function in orange imprints of buttons & knobs will be

activated Quick press on Shift key to activate setting of UVL,UCL,W.

Lock LED

Indicates the panel of power supply is being locked. This LED will being ON when press button. Then

the output is ON.

Fig. LED in button panel

Output ON/OFF LED

Indicates output ON / OFF status

Preset A LED

Indicates Preset A is selected, the output voltage and current are fixed as in preset A settings.

Preset B LED

Indicate Preset B is selected, the output voltage and current are fixed as in preset B settings.

Preset C LED

Indicate Preset C is selected, the output voltage and current are fixed as in preset C settings.

Adjusting output voltage and current

Voltage adjust knob

Adjust output voltage

-Rotate Voltage Knob clockwise to INCREASE output voltage.

-Rotate Voltage Knob anti-clockwise to REDUCE output voltage.

-Press Voltage knob to switch between COARSE and FINE adjustment. When press the knob the digit

will be high-lighted for tuning.

Current adjust knob

Adjust output current limit

-Rotate Current Knob clockwise to increase output voltage

-Rotate Current Knob anti-clockwise to reduce output voltage

-Press Current knob to switch between COARSE and FINE adjustment. When press the knob the digit

will be high-lighted for tuning.

Set upper voltage limit and upper current limit

Upper voltage Limit

This safety feature prevents test piece expose to damaging high voltage due to changes in load or current

setting. Also the warning UVL comes up with the set voltage value to remind user that the newly adjusted

output voltage has exceeded the UVL.

Adjusting upper voltage Limit

·The second function of Voltage Knob is for UVL adjustment.

·Press and LED is ON.

·Then press Voltage Knob. The display will show as follow,

·Rotate Voltage Knob to adjust the UVL value.

SSP-9080 User manual

·Press to confirm setting. If the new UVL value is lower than set output voltage, it will show

UVL Error alert.

Just reduce the set output voltage to lower than the UVL value. Then the UVL Error will be OFF.

Upper current limit (UCL)

The Upper Current Limit is feature to let user to set maximum value for current adjustment. This feature can

help to prevent unintentional setting for maximum output current to damage test piece.

When increasing output current and hit the UCL threshold limit the display will show you alert as following

Adjusting upper current limit

·The second function of Current Knob is for UCL adjustment.

·Press and LED ON

·Then press Current Knob. The display will show as following,

·Rotate Current Knob to adjust the value.

·Press to confirm setting. If the new UCL value is lower than set output current, it will show

UCL Error alert.

Just reduce the set output current to lower than the UCL value. Then the UCL Error will OFF.
