Only in one review: Voltage 70 V (NVVV S-800-70); Current 11.4 A (NVVV S-800-70); Under load 57.13 V (NVVV S-800-70); Ripple 500 mV (NVVV S-800-70); Power factor 0.75 (UPS-1000); No load 6 W (NVVV S-800-70); Protection 11.5 A (NVVV S-800-70); Temperature rise 230 °C (NVVV S-800-70); Weight 11400 g (UPS-1000).

UPS-1000: The UPS impresses with fast charging and robust construction, but switches to battery more slowly than specified and is noticeably noisy.

NVVV S-800-70: A decent, stable power supply, but it needs modification because of overheating resistors and a noisy fan.
