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.

The BK 1692 Switching Mode DC Power Supply provides high current output in a lightweight and compact package. It is suitable for a variety of uses, especially for powering DC operated mobile radio equipment on the bench. It provides a variable voltage output from 3 V to 15 V at 40 A continuous operation. In addition a fixed 13.8 VDC output is also selectable by a slider switch. Switching mode power supplies have the advantage of lightweight and high efficiency when compared to traditional linear mode power supplies. The efficiency can exceed 80% under the best conditions. Advanced circuitry protects against overload and provides immunity from RFI. A bright red and green LED display provides for an accurate and highly readable indicator of settings.

• High Efficiency: The unit is operated with efficiency over 80% under the best condition.
• Overload Protection: The current foldback 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.
• High RFI Stability: The high protection circuitry against RFI (Radio Frequency Interference) provides a stable operation.
• Variable Voltage Output: The output voltage is variable from 3V to 15V. A fixed 13.8V is also provided.
