Data Sheet High Current Switching DC Power Supplies Models 1693 & 1694 High Current at a Low Price Features and Benefits Up to 60 A output current B&K Precision models 1693 and 1694 switching Switching power supplies have the advantage of mode DC power supplies provide high current being lightweight and high in efficiency when Lightweight and compact output in a lightweight and compact form factor. compared to traditional linear mode power Dual 3-digit LED displays These 900W power supplies provide a variable supplies. The efficiency of the 1693 and 1694 Remote sense terminal voltage output from 1V to 15V at 60A (model can exceed 85% under optimal conditions. These Analog remote control via external voltage 1693) or from 1V to 30V at 30A (model 1694). power supplies are also designed with advanced source or variable resistor In addition, a remote sensing terminal is available circuitry to protect against overtemperature and Current foldback circuitry with illuminated to compensate for voltage drop across the load overvoltage conditions. Combined with bright leads. LED displays, the 1693 and 1694 are ideal for indicator prevents overloading the power users who want a reliable and easy-to-use supply The analog remote control feature can be used high-current DC power supply for system or Overtemperature protection circuitry to control the output voltage or turn the output bench use. Overvoltage protection on/off.
