FAQ
The B15 variant provides up to 15 A of field current output, making it ideal for medium to large generator systems.
Q2: Can it be used for both 50 Hz and 60 Hz systems?
Yes. The DECS-100-B15 automatically detects and adapts to either frequency.
Q3: Does it support communication with SCADA or remote systems?
Absolutely. It supports Modbus RTU communication through an RS-485 interface.
Q4: What happens if voltage sensing is lost?
The unit includes built-in loss-of-sensing protection, which activates field excitation shutdown to prevent damage.
Q5: How often does it require maintenance?
Routine maintenance is minimal—periodic inspection and firmware checks ensure optimal performance over years of operation.
