Summary: This booster is nearly identical to the Digitrax DB210, except that the DB220 features 2 boosters delivering twice the power. The DB220 can output up to 8 Amps with selectable voltage for various scales. The DB220 does not include a power supply. If opto-isolation is required, use a DB210 with opto-isolation.

The DB220 boosters are add-on components for existing Digitrax layouts. This booster features 2 channels with up to 8 amps of current each, for a total of 16 amps. With a flip of a switch, the booster can be set for 3-, 5-, or 8-amp output. The primary difference between the DB220 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 DB220, a DC power supply is required. The DB220 can accept DC input from 13.8v to 24V, at 6, 10, or 16 amps, depending on the selected output current capability. Although the manufacturer recommends the use of their power supplies, any stable high-quality DC power supply will work fine.
