SPS-9600/SPS-9602
High Current Switched Mode Power Supply with Remote Sensing & Control
User Manual
1. INTRODUCTION
These 900W switched mode DC regulated output power supplies provide a high current output with
constant current limiting protection. They provide a variable output: 1~15VDC for SPS-9600 and 1~30VDC
for the SPS-9602. They are designed with a high efficiency Active Power Factor Correction circuit. Remote
sensing terminals are provided to compensate for long output cable losses. The output voltage level can be
controlled by the front panel or externally via remote control. A remote ON/OFF is also provided.
2. PRECAUTIONS
CAUTION! The AC input is internally DOUBLE POLE FUSED
● The power supply is for Indoor Use Only.
● Never Short the Remote Sensing Terminals
● Do not expose the power supply to direct sun, high humidity or dusty environments.
● Never remove the cover of the power supply whilst the AC power is connected.
● Never touch the unit when your hands are wet.
● Never block the ventilation slots and cooling fan air outlet.
● Never attempt to repair the power supply. Refer all servicing to qualified personnel.
● Never use the power supply for a load requiring higher current than the maximum rating otherwise it
may damage the power supply.
● Always place the power supply on a flat surface with sufficient clearance and with dry, dust free
surroundings for ventilation.

4. CONNECTION
4.1 The SPS-9600 series has 2 models. Make sure you have purchased the correct one.
The models have different output voltage ranges and maximum current as follows:
Model Number Output Voltage Range Total Rated Current (Main+Aux)
SPS - 9600 1 ~ 15V 60A
SPS - 9602 1 ~ 30V 30A
4.2 Check the rating label of the power supply and make sure it complies with the AC mains voltage.
Connect the power supply to the AC Mains using the power cord provided.
4.3 REMOTE SENSING – Take note of all warnings and follow the order of installation exactly.
Warning! Never short the Remote Sensing Terminals.
Connection:
1. First complete the power connections between power supply and your equipment.
2. Check that the power supply’s connections are secure.
3. Then complete the connections between Remote Sensing and your equipment.
Warning! CHECK that the Remote Sensing Terminals have the correct polarity!
Dis-connecting:
1. Disconnect the remote sensing connections first.
2. Then disconnect the power connections between the power supply and the equipment.
Fig 3 shows the connections between Remote Sensing, Power output and Equipment.
Fig. 3
The remote sensing wire should be AT LEAST 22AWG gauge wire.
4.4 REMOTE CONTROL
There are two methods for the remote control of the voltage using the remote control connector
(9). Both methods apply a voltage between 0 and 5 Volts to the control pin 2. One method is to
use an external voltage source such as the output from a DAC (Digital to Analogue Converter).
The other method is to use the internal +5V DC provided on pin 1 and a 5kΩ potentiometer to
provide the 0 to 5 Volts required.
Fig 4. Using one 5k ohm variable resistor or potentiometer to control the output voltage.
NOTE: Switch the Remote Control ON/OFF switch (9), on the rear panel, to the ON position to use the
Remote Control option. Switch to the OFF position to use the Voltage Control (3) on the front panel.
