4. TECHNICAL SPECIFICATIONS

The M16FA655A voltage regulator can be calibrated using potentiometers. The circuit board is
resin-bonded in order to maintain a high degree of operational reliability even in difficult
environmental conditions (high levels of humidity, dust, a salty atmosphere) and in the presence of
vibrations.
