Feature 1 Voltage regulator supports underspeed protection with adjustable threshold and slope, which is also with overvoltage and undervoltage alarms. 2 Excitation overcurrent protector with anti-degassing port can supports insufficient excitation or excitation loss alarm. 3 Management of temporary short circuits supports starting of asynchronous motors. 4 Open collector output non-insulated informs some alarm interventions via programmable activation signals for each alarm, as well as the possibility of intervention delays and selectable activity levels 5 With operating time of memory regulator, voltage regulator keeps USB communication interface with optional US B2D x R module.Item Type: Voltage regulatorModel: DER1Digitally Controlled Voltage Regulator: Based on digital signal processing Application: All for Mecc Alte self-tuning alternatorsQuick Connector: Connect via 20 pole power supplyProtect Power Winding: 5A fast fuseSignal Connection: (Pext, 60Hz jumper.
