The ELECTRA MOLINS AUT-MP12 is a microprocessor-based automatic control panel designed for industrial generator sets in emergency standby and prime power applications. Its defining architectural feature is the separation of control tasks across three independent processors: one dedicated to electrical measurements, one to genset operation logic and sequencing, and one to external communications. This parallel processing architecture ensures measurement accuracy and response time are not compromised by simultaneous communication or display update tasks.

What does the triple-processor architecture improve in practice?

In a conventional single-processor genset controller, the CPU must time-share between sampling voltage/current waveforms, executing the start/stop state machine, updating the display, and servicing Modbus requests. The AUT-MP12 assigns each function to a dedicated processor, so true RMS measurement continues uninterrupted during mains failure detection, engine cranking, and transfer sequences. Harmonic analysis — typically the first feature dropped under CPU load — runs continuously and is displayed alongside fundamental electrical parameters on the TFT screen.

How does AUT-MP12 handle extreme environments?

With an operating temperature range of -30°C to +70°C, the AUT-MP12 is suitable for generator installations in unheated outdoor enclosures and desert-climate engine rooms alike. The panel includes a built-in electronic battery charger to maintain the starter battery during extended standby periods, and supports configurable periodic self-test starts to verify genset readiness without manual intervention.

What variants are available for multi-genset systems?

For applications requiring load transfer control separate from the genset controller, the AUT-MP12DR variant pairs with the CON-2012 independent transfer module. For sites with multiple generators operating in parallel, the MP12-SCR module adds automatic synchronization and load sharing using either fast electrical-axis or classical synchronization methods.
