4. TECHNICAL SPECIFICATIONS

The M40FA610A/A 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.
