Supporting use in laboratories and on manufacturing lines, N8937APV (208 Vac) and N8957APV (400 Vac) help engineers develop, verify, and maximize performance of inverter maximum power point tracking (MPPT) algorithms and circuits. Both single-output, programmable DC power sources can simulate I-V curve characteristics under different environmental conditions. Additionally, simulators provide built-in voltage and current measurements and autoranging output from 500–1,500 V and 10–30 A.
