Limited version of a real UPS
2 personnes sur 2 ont jugé cet avis utile. This UPS puts out a very minimal PWM bipolar pulse in place of the 120 VAC sine wave from the wall outlet. The energy in the PWM pulses is only about 70% of that of the equivalent sine wave, meaning that any unit powered by it (even at very light loads) is essentially in a state of continuous brown-out. In other words, plug in a 20 watt lamp and switch off the primary power. The light output will drop in half or more.
If I had bought the unit new, I would have sent it back. However, I bought it used and at a MAJOR discount off list. As such, it serves its minimal purpose and I have it in service at this time.

Good thermal adhesive for SMT
Standard thermal adhesive. Seems to work fine. Less expensive than most other sources.
