The BK Precision 9115B230V Programmable Multi-Range DC Power Supply, 80V/60A, 1200W automatically recalculates voltage and current limits for each setting, providing full output power in any Volt/Amp combination within the rated voltage and current limits. This model provides a numerical keypad for direct data entry along with convenient cursors and analog style knobs to quickly make incremental voltage or current changes. The 9115B comes with built-in OVP (overvoltage protection), OTP (overtemperature protection), and OLP (overload protection) circuitry. These protections help prevent serious damage to equipment in case of power supply failure.
