Remoran PR-01 Protection Relay

Remoran PR-01 Protection Relay protects the charger from overvoltage.

The fully automatic Remoran PR-01 protection relay protects the Remoran Charger 300W from generator (outboard unit) overvoltage. A potential overvoltage condition occurs when the generator rotation exceeds the design speed. If you often sail close to maximum speeds, we recommend using a protection relay..

Remoran PR-01 temporarily disconnects charging preventing the overvoltage from breaking the charger. The PR-01 receives the electrical energy needed for operation from the three-phase generator voltage and is therefore ready for operation as soon as the generator begins to generate voltage (the boat is moving). The PR-01 measures the generator voltage level and, if necessary, disconnects the connection between the outboard unit and the charger, thus protecting the charger from overvoltage. When the speed of the boat decreases and the generator voltage drops, the PR-01 restores the electrical connection between the generator and the charger and the charging function resumes.
