This unit is self powered and has a sensor that can either automatically start the belt when it senses mail, or you can set it on continuous mode. Because it is self powered, if you don't use Hasler or NeoPost, you can use it for any mail system you have. The unit measures 37" (L) x 12" (W) x 10" (H). The stacker at the end extends from 8.5" to 15". Comes with a power cord.
