The SPS-8400 Switching Mode DC Power Supply provides high power output with its
small size and lightweight. It is suitable for a variety of uses, especially for DC operated radio equipment
source from an AC outlet and providing variable voltages of 3V to 15V under 40A continuous operation.
Lightweight and Small Size: Switching mode power supply has the advantages of lightweight and
small size. Comparing with linear mode power with the same power output, it is much lighter and
High Efficiency: The unit is operated with efficiency over 80910 under the best condition.
Overload Protection: The constant current circuitry is adopted to prevent from overload. The
overload indicator will be lighted up when the unit is overloaded.
Over Temperature Protection: The over temperature circuitry is functioned when the unit is over a
certain high temperature to prevent the unit from damage by the high temperature. When the
circuitry is functioned. the output voltage and current will drop down to a safety value and the
overloaded indicator will be lighted up.
Over Voltage Protection: The over voltage circuitry protect the unit and the loading equipment from damage by abnormal high output voltage.
High RFI Stability: The high protection circuitry against RFI (Radio Frequency Interference)
provides a stable operation.
Variable Voltage Output: The variable range of output voltages from 3V to l5V enables good fits
with various uses
