Chapter 1 Introduction
SPS8 series power supply is high performance single-output programmable DC power supply with
communication interface, possessing the character of fast rise time speed (The rise speed of SPS811 power
supply can be less than 10mS and the SPS851 can be less than 20ms). The combination of bench-top and
system features in SPS8 power supplies provides versatile solutions for your design and test requirements. The
SPS8 series can not only be programmed through the keyboard on the panel, but also be functioned as
voltmeter and milliohmmeter, which will bring great convenience to the users. As a regeneration product of
ordinary programmable power supplies, SPS8 series power supply is more cost-effective.
SPS831 power supply, a new generation of programmable linear power supply, are designed with high speed
dynamic programming output (Voltage 0-30V, 1ms rising time), high current accuracy (0.001mA resolution)
and low internal resistance, which can satisfy all the test requirements. Meanwhile, the voltage level switch
works without relay, which will cause the fast switch between high voltage and low voltage. Moreover, SPS831
power supply provides the best solutions for cellphone research, micro-electronics lab, research institute and
special users requiring power supply with low current but high accuracy.
Features
Low ripple and noise
High resolution and accuracy (0.1mV/0.01mA, SPS831 reaches up to 0.001mA)
Built-in a high-accuracy 5 1/2 voltmeter and milliohmmeter
Supporting high-accuracy and dynamic programming output
High-luminance VFD screen and two lines & four ways display
Smart fan will be automatically initiated according to the temperature
Supporting remote voltage compensation and multidata storage
Supporting external trigger input and output
Power-on-self-test, software calibration and standard rack mountable
Supporting RS232/RS485/USB interface

Chapter 3 Quick Start
This chapter mainly focuses on the brief introduction of the surface appearance and basic functions of SPS8
series power supply so that both experienced and inexperienced users can be acquainted with the new products
quickly. Meanwhile, the chapter also clarifies some preliminary checkout that should be made prior to
operation to make sure the normal running of the products.
3.1 Front Panel and Rear Panel
The front panel layout of SPS81X series power supply is as follows:
Diagram 3.1 Front Panel of SPS81X Series Power Supply
The upper half is black VFD display screen and knob
The bottom half, left side to right side, is numberic keys 0-9, esc key, function keys, up-down keys,

③9-pin serial port interface connector
④line voltage selection switch (110 VAC or 220 VAC)
⑤AC input connector
3.2 Preliminary Checkout
The following steps help you verify that the power supply is ready for use.
1. Check the list of supplied items
Verify that you have received the following items with your power supply. If anything is missing, contact your
nearest sales office.
One power cord for your location
One CD (only when you have bought communication accessories)
One communication cable (only when you have bought communication accessories)
One test line (only SPS811 ,SPS812 ,SPS813, SPS831 have the test line)
2．Connect the power cord and turn on the power supply
When you turn on the power supply, the VFD display screen will light up briefly and the power supply
performs its power-on self-test. Please check if there is any stroke loss on VFD display.
Warning:Your power supply is equipped with a 3-wire grounding type power cord. The power
supply is grounded only when the power-line cord is plugged into an appropriate receptacle. Do not
operate your power supply without adequate cabinet ground connection.
3.3 If the Power Supply Does Not Turn On
Use the following steps to help solve problems you might encounter when turning on the instrument.
1.Verify that there is AC power to the power supply.
First, verify that the power cord is firmly plugged into the power receptacle on the rear panel of the power
supply. You should also make sure that the power source you plugged the power supply into is energized. Then,
verify that the power supply is turned on.
2. Verify the power-line voltage setting.
The line voltage is set to the proper value for your country (110VAC or 220VAC) when the power supply is
shipped from the factory. Change the voltage setting if it’s not correct.
3. Verify that the correct power-line fuse is installed.
If the fuse was damaged, please see the table below to replace the fuse for your power supply.

4. How to replace the power-line fuse
Open the plastic cover which locates at below the power input socket in the rear panel of the power supply by
screwdriver, then you will see the fuse. Please replace the damaged fuse with the matched fuse.
3.4 How to Adjust the Carrying Handle
To adjust the position, grasp the handle by the sides and pull outward. Then, rotate the handle to the desired
position. There are following three positions for you to choose:

4.2 Front-panel Operation Overview
The following section describes an overview of the front-panel keys before operating your power supply.
The power supply is shipped from the factory configured in the front-panel operation mode. At power-on,
the power supply is automatically set to operate in the front-panel operation mode. When in this mode, the
front panel keys can be used.
When the power supply is in remote operation mode, you cannot use the front-panel. A change between
front-panel and remote operation modes will not result in any change in the output parameters. You can
change the front-panel and remote operation modes by PC.
The output of the power supply can be enabled or disabled from the front panel by pressing the key
.
The VFD display shows the current operating status of the power supply with annunciators. When it is
powered on, the VFD will display two lines of data. The first line shows the actual voltage value, actual
current value and power supply’s status while the second line shows the voltage value that can be
measured by voltmeter and output setting value of the power supply.
4.3 Constant Voltage Operation
The constant voltage range is from 0V to the maximum voltage value of each model. It is very easy for you to
set the constant voltage output. You have 2 solutions to set the constant voltage value.
Solution 1:
Press the ▲ and ▼ keys to change the value when the SPS8 series power supply is powered on.
Solution 2:

Step2. Press key
Step3. Use the numeric keys to to enter the voltage value you wanted
Step4. Press key to confirm the value
If you close knob lock function in config menu, please use following operation:
Press key then use upper revolving encoder to adjust voltage
4.5 Saving and Recalling Operation
You can store up to 50 different output states in storage register locations(0~49) so that you can recall the saved
settings quickly. This kind of store operation can be performed by the keys and located in
the front panel. When the fast recalling is activated, you can press the numberic keys to to invoke
the corresponding data.
Each output state includes: 1. Constant voltage value, 2. Constant current value, 3. Maximun voltage setting
value, 4. Step voltage value.
After you setting an output state (CV value, CC value and Maximum voltage), press the key
and the numeric keys to to store the output value in a specified memory location.
Press the key and the numeric keys to to recall the output value from a specified memory
location.
