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 in5V DC provided on pin 1 and a 5k
Ω
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.
