BK 1692 SWITCH MODE POWER SUPPLY
USER’S MANUAL
INTRODUCTION
The BK 1692 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.
Please read through this operation instruction carefully and follow the instructions to prevent from
abuse or misuse. This manual must be kept for reference at anytime in need.
FEATURES
1. Lightweight and Small Size: The BK Precision 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 smaller.
2. High Efficiency: The unit is operated with efficiency over 80% under the best condition.
3. Overload Protection: The current foldback circuitry is adopted to prevent from overload. The overload
indicator will be lighted up when the unit is overloaded.
4. 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.
5. Over Voltage Protection: The over voltage circuitry protect the unit and the loading equipment from damage
by abnormal high output voltage.
6. High RFI Stability: The high protection circuitry against RFI (Radio Frequency Interference) provides
a stable operation.
7. Variable Voltage Output: The output voltage is variable from 3V to 15V. A fixed 13.8V is also
provided.

Note: The fixed 13.8Vdc output selection switch is placed at the bottom of unit. It used to select the
output voltage to fixed 13.8V or 3-15V adjustable output (controlled by adjustment knob ).
INSTALLATION
1. Make grounding the unit to prevent from electric shock at high voltage caused by leakage or lightning.
2. DO NOT place the unit in high humid, dusty and/or sunshiny places.
3. Place the unit in a location where allows free air circulation.
4. DO NOT place the unit close the TV sets or CRT monitor.
