Victron Energy Cyrix-Li-load 24/48V-230A – High-Current Load Disconnect Relay for Lithium Systems (CYR020230450)

The Cyrix-Li-load 24/48V-230A is a smart load control relay engineered for 24V and 48V lithium battery systems managed by a VE.Bus BMS. It disconnects loads automatically when battery voltage drops or in the event of temperature alarms, helping to preserve battery life and system integrity. Featuring a 230 A continuous current rating, 80 A breaking capacity at 48V, and intelligent delay-based reconnection, it ensures maximum safety and minimal downtime in high-power setups.

Key Features
- Supports 24V and 48V LiFePO₄ battery systems with VE.Bus BMS
- 230 A continuous current handling; 80 A breaking capacity at 48V
- Automatic load disconnect on BMS undervoltage or thermal signal
- 3 re-engagement attempts before requiring voltage recovery
- LED status indicator with fault diagnostics
- Includes 1-meter control cable
- Built-in transient voltage suppressor for switching protection
- Very low idle current draw (<4 mA)
Voltage-Based Switching Logic
