BSM-21 Microprocessor based system controller
brings you better control & central point monitoring
over your DC Power system one unit allows perfect
control and monitoring of BSM-24-1500 and
BSM-48-1500 Rectifiers.
The major characteritics of the monitoring is its ease
to operate. A simple four click touch board enables
reading of data and setting of parameters. Not only
does it monitor the status of rectifiers such as output
current and operating mode, it also measures output
voltages, battery temperatures, breaker status, mains
availability, intrusion etc. The monitor can easily be
operated locally by reading its LCD display or
remotely via its communication port RS 232/ RS 485
compatible.
