We often get some questions that what's the difference between your UPS & Power supplies and other UPS? 

Why are your UPS' is more expensive than those open frame power supplies?

TERACOM UPS can be considered as "UNDER-RATED". The Rated Power is actually higher than you can measure.

We use standard rating to promote our power supplies. For example, when we promote TS-SIHD1203N-01B, we usually will say it's 12V 3A (36W) UPS, excluding the battery charging current. The output has definitely 3A to the load, and ADDITIONAL 1A (Max) charging current. TERACOM 36W power supply actually has 54.4W rated power while the open frame 35W has 35W rated power. Same as the 60W UPS

Open frame power supply promotes with full power, including charging current. You can see their rated power is the same as they promote in their model no.

It's applied to all of TERACOM power supplies. The power of most TERACOM power supplies is 1.5 TIMES HIGHER than what it shows in the model no. its stating.
