The DM110 is a digital, 2-phase sensing, permanent magnet generator (PMG) or auxiliary winding powered automatic voltage regulator (AVR) incorporating VAR/Power Factor control.

Cummins Generator Technologies in conjunction with Basler Electric have developed a high powered, digital excitation control system, the DM110, The DM110 is produced by Basler for STAMFORD® – AvK® products

This environmentally rugged product is ideally suited for controlling the output of STAMFORD® and AvK® brushless synchronous generators up to 5MW. The DM110 has an impressive 7Adc output from a pulse width modulated power stage. The DM110 is perfect for machines that will be paralleled to other generators and/or to the utility system. It is ideal for distributed generation, cogeneration and peak shaving applications. The DM110 is easy to use, and it has communications capability with a PC for the initial set up, adjustment and maintenance. The DM110 utilizes microprocessor technology and control algorithms pioneered by Basler Electric, for more than a decade.

The DM110 is a microprocessor-based regulation system designed to control the output of AvK® and STAMFORD® brushless, synchronous generators. The DM110 is perfect for paralleling applications where generator to generator and/or generator to utility paralleling occurs with VAR/PF control and Over- and Under-excitation Limiting. The DM110 offers high functionality communications and performance unique to the STAMFORD® - AvK® synchronous generators. The DM110 is very rugged and offers an extremely robust mechanical design that is cURus recognized, CE compliant, and DNV certified.
