Remoran PR-02 Protection Relay for Remoran Charger 300W

The Remoran PR-02 Protection Relay safeguards your Remoran Charger 300W hydrogenerator system by preventing damage caused by generator overvoltage.

When a sailboat reaches high speeds, the generator may rotate faster than its designed limits, creating an overvoltage condition that could potentially damage the charger. The PR-02 relay automatically monitors generator voltage and temporarily disconnects the charging circuit if unsafe voltage levels occur.

Once the boat speed decreases and voltage returns to safe levels, the PR-02 automatically reconnects the generator and charging resumes - ensuring reliable and uninterrupted energy production while protecting your system.

Designed for seamless integration with Remoran hydrogenerator systems, the PR-02 operates automatically and draws the energy required for operation directly from the generator itself.

Key Features

• Automatic Overvoltage Protection - Protects the Remoran Charger 300W from generator overvoltage
• Smart Voltage Monitoring - Continuously measures generator voltage levels during operation
• Automatic Disconnect Function - Temporarily disconnects charging if voltage exceeds safe limits
• Auto Reconnection - Restores charging automatically once voltage drops to safe levels
• Self-Powered Operation - Powered directly from the three-phase generator voltage
• Essential for High-Speed Sailing - Recommended for boats frequently sailing near maximum speeds

How It Works

1. The hydrogenerator begins producing electricity as the boat moves.
2. The PR-02 relay continuously monitors generator voltage.
3. If generator speed produces excessive voltage, the relay temporarily disconnects the charger.
4. When boat speed decreases and voltage normalizes, the relay reconnects the system and charging resumes.

This fully automatic protection ensures safe, reliable power generation without manual intervention.

What's Included

The Remoran PR-02 Protection Relay includes:
