Procon SPS-9620 User Manual

SPS-9620 SWITCH MODE POWER SUPPLY
INTRODUCTION
The SPS-9620 Switch Mode DC Power Supply provides high power output for its small size and weight. It is suitable for a
variety of applications, for example operating low voltage radio equipment from an AC mains outlet, and provides
13.8Volts at up to 120 Amps. It provides high efficiency, active Power Factor Correction (PFC) and remote voltage
sensing to compensate for long cable connections.
Please read these instructions carefully and follow them to prevent abuse or misuse of the power supply. These instructions
must be kept for future reference.
FEATURES
1. Lightweight and small in size: This switch mode power supply has the advantage of small size and weight in
comparison to linear mode power supplies.
2. High Efficiency: This unit operates with efficiency greater than 85% under normal conditions.
3. Overload Protection: Current limiting circuitry is used to prevent overloading of the power supply. A front panel
indicator will illuminate when overload conditions occur.
4. Over Temperature Protection: To prevent damage to the unit when high temperature conditions occur, the over
temperature circuitry operates to reduce the power supplies output to a safe level.
5. Over Voltage Protection: The over voltage circuitry operates to protect the power supply and the load from
excessively high output voltage. Remove any external voltage and then switch off the power supply for 30
seconds or more before switching it on again to restore operation.
6. High RFI Stability: Protection circuitry is provided against RFI (Radio Frequency Interference) that ensures stable
operation of the power supply in adverse conditions.
7. Output Voltage Adjustment: A variable pot adjusts the output voltage from 11V to 14V enabling the power supply
to be used in a variety of applications. Adjustment between 5V and 15V is available from Procon Technology.

INSTALLATION
1. Ensure that the unit is properly grounded through the AC mains plug. This will prevent electric shock due to
leakage should a high voltage surge or lightning strike occur.
2. DO NOT place the unit in dusty or highly humid locations. DO NOT place the unit in direct sun-light or
locations subjected to high temperatures.
3. Place the unit on a flat surface in a location which provides unobstructed air circulation.
4. DO NOT place the unit close to TV sets or CRT monitors.
5. Connect the unit directly to the AC mains outlet. DO NOT use an extension lead or adapter as these may become
overheated.
