The pulsed evaporator (without control) is optimized for digital voltages of 20-24V track voltage and creates its optimal amount of steam. The evaporator has been developed so that it can also run dry (but not recommended in the long term) without being damaged. The evaporator without control is suitable for direct connection to our locomotive decoders from the DRIVE series as well as to our GVS (if no DRIVE decoder is available). It already has an integrated voltage control for the fan. The evaporator can therefore be used for both steam locomotives and diesel locomotives. The steam quantities for all states (driving, rolling, acceleration, stationary) can be set separately in the decoder. The connection is valid for all DRIVE decoders (except DRIVE-S). The connection is very simple to t.
