Digitrax: DB220

Summary: This booster is nearly identical to the Digitrax DB210, except that the DB200 has 2 channels delivering 2x the power. The DB220 can output up to 8 Amps of power and has a voltage selector for various layout scales. This booster does not include a power supply. It accepts a DC voltage range between 13.8 to 24v. If you need opto-isolation, you'll need to stick with the DB210.

The DB220 boosters are add-on components for existing Digitrax managed layouts. This booster allows for up to 2 channels each with up to 8 amps of current, for a total of 16 amps. With a flip of a switch, the booster can be set to 3, 5, or 8 amps output. The primary difference between the DB210 and DB210 Opto is the opto-isolation capabilities for common rail wiring, however, for DCC, it's recommended to not use common rail wiring.

In addition to the DB210, a DC power supply is required. The DB210 can accept DC input from 13.8v to 24v, with amp requirements of 6, 10, or 16 amps, depending on what has been selected as the output current capability. Although the mfr recommends the use of their power supplies, and stable high-quality DC power supply will work fine.
