The PCR-LE2 series is high-end programmable AC power supply with full linear amplifier topology, upgraded from classic PCR-LE series. One single unit supports one-touch switching of single-phase / single-phase 3-wire / three-phase output modes without extra option boards, greatly simplifying test system construction. Five models cover high power range 6 kVA ~ 27 kVA. Adopting pure linear amplifier circuit, it delivers ultra-low waveform distortion and fast transient response, serving as benchmark AC source for grid-tied inverters, new energy vehicles, EMC compliance and power standard testing
