The PS-1250 is the sixth-generation model in the series that began with the PS-1200, serving as a high-capacity clean power supply. It features an LCD panel that allows users to visualize input and output waveforms—realizing a long-held ideal—and verify the effectiveness of the waveform shaping. A high-precision reference signal, generated without the use of an oscillator, is fed to the waveform correction amplifier via balanced transmission. This amplifier employs a "20-parallel push-pull circuit using bipolar power transistors," achieving both low distortion and a high output capacity of 1200 VA. Additionally, the unit is equipped with ten hospital-grade AC output terminals that meet rigorous standards for high quality, safety, and reliability. Wiring from the output circuit to each AC terminal is matched in length to ensure consistent sound quality across all outlets.
