High Current Switching DC Power Supplies
Models 1693 & 1694
High Current at a Low Price
B&K Precision models 1693 and 1694 switching mode DC power supplies provide high current output in a lightweight and compact form factor. These 900W power supplies provide a variable voltage output from 1V to 15V at 60A (model
1693) or from 1V to 30V at 30A (model 1694). In addition, a remote sensing terminal is available to compensate for voltage drop across the load leads.
Outputs/Model 1693 1694
Variable Output Voltage 1 - 15 V 1 - 30 V
Output Current 60 A 30 A
Switching power supplies have the advantage of being lightweight and high in efficiency when compared to traditional linear mode power supplies. The efficiency of the 1693 and 1694 can exceed 85% under optimal conditions. These power supplies are also designed with advanced circuitry to protect against overtemperature and overvoltage conditions. Combined with bright LED displays, the 1693 and 1694 are ideal for users who want a reliable and easy-to-use high-current DC power supply for system or bench use.
