Pros:
Compact size, high VA rating.
Cons:
The UPS is not silent. It has a fan in it that runs constantly. Though the fan is pretty quiet, I bought it for an entertainment center in my living room and it was too noisy. The biggest mis-advertisement with this UPS is the "PWM sinewave" output -- it is really a stepped SQUARE WAVE (-, 0, +) and will NOT drive my TV. I did not get what I thought I was buying -- PWM can be used to efficiently synthesize a quality waveform, but the specs on this UPS are plain mis-leading. Coming from a smaller APC smart UPS, the features on this UPS seemed to leave a lot to be desired. The communications capability seemed very basic based on the docs, though I did not have a chance to try them. I almost returned the unit, but gave it to a friend instead.
Comments:
Works fine for most computer equipment. Good price. Not recommended for A/V or where noise is an issue. Mediocre communication and configuration. Misleading "PWM sinewave" output is really a stepped square that works OK with most power supplies, but not everything.
