AVR AUTOMATIC VOLTAGE REGULATOR FOR GENERATOR MODEL DSR by MECC ALTE

AUTOMATIC VOLTAGE REGULATOR AVR MOD. DSR, DIGITAL, FOR MECC-ALTE ALTERNATORS AND MORE, GENERATOR SET VERSION

Item Description:

AVR digital voltage regulator model DSR completely digitally controlled and is fitted as standard in all ECO and ECP series alternators by MECC-ALTE.

Connections on the DSR are via 15 fast on/fast off connectors which speed up the connection process. This is particularly useful if you need to reconnect a 12-wire machine to a specific voltage. This regulator is compatible with all ECO and ECP series machines and can be used as standard with the MAUX system and PMGs, so there is no need to change regulators. Its standard reference is single phase.

Connection is available via the external communication card (DxR or DL1), connection to the PC (RS232 or USB) or PLC connection (RS485 via MODBUS). This allows you to change the regulator settings, monitor performance in real time (Voltage, Frequency or DSR status), or download the alarm report (the communication software is available from Mecc Alte).

DSR functionality

• Possibility of analogue remote control of the output voltage or with a 10Kohm linear potentiometer
• Low speed protection with adjustable threshold and slope
• Overvoltage and undervoltage alarm
• Excitation overcurrent protection with delayed intervention
• Management of transient short circuits (starting of asynchronous motors)
• Open collector output (not isolated) signaling protection intervention with programmable activation with respect to individual alarms, possibility of intervention delay and selectable active level
• Storage of abnormal operating conditions (type of alarm, number of events, duration of the last event, sum of times)
• Memorization of the operating time of the card (starting from Firmware version 11)
• USB communication interface (with optional USB2DxR module)
