The BK Precision 9115AT Programmable Multi-Range DC Power Supply with Automotive Test Function, 80V/60A, 1200W provides automotive power test waveforms compliant to DIN 40839 and ISO 16750-2 standards that can simulate common test conditions for electrical and electronic devices installed in automobiles. This model 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. The numerical keypad allows direct data entry along with convenient cursors and analog style knobs to quickly make incremental voltage or current changes. The 9115-AT 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.
