1. Introduction
SM-8800 is a multi-function electronic load machine designed for every kind of S.P.S. It especially
provides departments like production, examination or development with easy manipulation board
displaying complete information. SM-8800 focuses on ATX Power and strengthens test function so
users can test a whole ATX Power once. We concern the hardwork of operators for their long working
hours. Therefore, SM-8800 displays bright numbers and English words. In automatic version, only
need to press “OK”. This complete and multi-function design offers operators a clean workstation.

1-3 Temperature protection
After SM-8800 is booted, the fan is at low speed. At this time, if the temperature increases
above 55℃, the fan changes into high speed. If the temperature decrease below 40
℃ at high speed, the fan will change into low speed.

2. Installation
2-1 SM-8800 and power cord connection
Please take out SM-8800 from the package. You can see a selection switch. (Please elevate
SM-8800 so that you can see the selection switch of 110V /230V) If indoor voltage is AC 230V,
please switch “Line Select” to 115V. Insert AC Power cord into the socket of SM-8800 rear panel
“Line AC Input”. Likewise, insert the other end into the indoor socket. Ground “F.G.” of SM-8800
rear panel so that it can prevent operaters from electric shock due to electric leackage. Refer to
figure 2-1.
2-2 SM-8800 and external AC source (Self-coupling transformer) connection :
Switch “Source Select” to “EXT” on SM-8800 rear panel. Refer to figure 2-2. Insert the
airline socket connected cord into airline socket “EXT Source Input” to connect IN-2 and
COM to output of self-coupling transformer. Insert output of self-coupling transformer into
the indoor socket.

2-3 SM-8800 and S.P.S. connection :
Take out AC power cord from the appendix. Refer to figure2-2. Use AC power cord to
connect “To S.P.S.” socket of SM-8800 rear panel and the socket of S.P.S. AC power input.
Refer to figure 2-4. Insert the output of S.P.S. DC into the socket of SM-8800 front panel in
the lower left side (such as ATX, ATX-20pin or 4P socket)
2-4 SM-8800 and Oscilloscope connection
Use the BNC cable in the appendix to connect BNC socket of SM-8800 and Oscillascope.
2-5 SM-8800 “I/O Port” (Input/Output) signal and external control circuit connection
2-5-1 Input signal and connection of external switch on I/O port of SM-8800 rear panel. Arrange
a control circuit. (Refer to figure 2-5-1a) Connect control switch (like button of pedal) with
related circuit on “R.C.” and “R.C. COM” ends of I/O port on SM-8800 rear panel. (Connection
mistake may damage the internal circuit of SM-8800.) Figure 2-5-1b is the output circuit of
“R.C. COM” ends on I/O Port”
