General Description
The DiMAX
®
1203B Digital Booster is based on the same technical specifications as the Di-
MAX
®
1200Z central station. The DiMAX 1203B features 3 discrete output amplifier stages
which deliver 10 Amps permanently (12 Amps in peaks) depending on the setting and the
operational mode. An overload protection and a temperature controlled fan are integrated.
The DiMAX 1203B Digital Booster provides 3 operational modes: booster, booster with a re-
verse loop function, and booster with a braking function. In addition the DiMAX 1203 is inde-
pendant of any digital protocol which makes it usable with NMRA compatible systems or any
other digital system.
