B& K Precision m odels 1 69 3 and 1 69 4 switching m ode D C power supplies provide high current output in a lightweight and com pact form factor. These 9 0 0 W power supplies provide a variable voltage output from 1 V to 1 5V at 60 A (m odel 1 69 3 ) or from 1 V to 3 0 V at 3 0 A (m odel 1 69 4). In addition, a rem ote sensing term inal is available to com pensate for voltage drop across the load leads. The analog rem ote control feature can be used to control the output voltage or turn the output on/off.
