DSR AVR Automatic Voltage Regulator for Mecc Alte Diesel Generator
The AVR DSR is an advanced AVR replacing the traditional automatic voltage regulator. This voltage regulator is fully digital controlled and is fitted as standard across all our ECO and ECP models
Connections on the DSR are through 15 fast on / fast off connectors which speed up the connection process. This is especially useful if reconnecting a 12 wire machine to any specific voltage. This regulator is cross-compatible with all ECO and ECP machines and can be used as standard with the MAUX system and the PMG ma systems, so there’s never any need to change regulators. Its single phase sensing comes as standard.
By means of the external communication board (DXR or DL1), computer connection (RS232 or USB) or PLC connection (RS485 via MODBUS) is available. This allows changes to the AVR settings, to monitor in real-time performances (Voltage, Frequency or DSR status), or to download the alarm report (Communication software is available from Meccalte).
