Behlman’s Model RR1200 is a Railroad Signal Power Source that has been supporting train operations for more than fifteen years, during which it has proven to be exceptionally reliable and able to withstand the rigors of remote, sometimes isolated, installation along rail routes that crisscross the USA.

The RR1200 Railroad Signal Source delivers 1200 VA of clean, regulated AC power in a compact, 3.5” high, bench top unit that easily converts to rack mount. It supplies a clean, low-distortion, 120 VAC sine wave at any fixed frequency from 50 Hz to 250 Hz, with excellent line and load regulation, high efficiency, and low harmonic distortion.

In addition, the Behlman RR1200 has a unique overload protection system that folds back voltage to maintain rated output current without waveform distortion. In the event of a short circuit, the unit will automatically reset upon overload removal. It also has a mechanical guard for the On/Off circuit breaker, plus AAR terminals on the rear for input and output connections.
