12VDC Input Transient Filter
The CPX2-173 display consoles require n12VDC at 40W for operation. An EMI line filter is provided to
limit EMI emissions and to provide a small measure of input filtering.
For operation from unregulated 12VDC (+/-10%) such as in a vehicular or marine environment, front end
transient filtering is required to suppress potentially damaging spikes from large inductive loads in the DC circuit
(starters, etc.).
The xxx 12VDC Input Transient Filter provides an input Transient Protection as well as inductive and capacitive
filtering to suppress large input transients. A bridge rectifier provides reverse connection protection. A circuit
breaker provides for failure protection and allows the power to be disconnected.
