Victron Cyrix-Li-load 24/48V-230A (CYR020230450) — is a specialized automatic high-current relay designed to open the load circuit when critical parameters of lithium batteries (LiFePO₄) are reached. It works in tandem with the VE.Bus BMS, which controls the state of the cells and transmits signals to turn on/off the Cyrix.
This model is adapted for 24 V and 48 V systems and is capable of switching currents up to 230 amperes. Cyrix-Li-load 24/48 is ideal for high-power power systems with a large number of consumers or inverters without built-in deep discharge protection.
Purpose and application:
- Protection of LiFePO₄ batteries against deep discharge
- Automatic load disconnection upon signal from VE.Bus BMS
- Use in 24 V or 48 V systems (automatic voltage detection)
- Solution for solar, autonomous and mobile systems with large loads
Technical specifications:
- Nominal system voltage: 24 V / 48 V DC
- Maximum current (continuous): 230 A
- Breaking capacity at 48 V: 80 A
- Control: digital input from VE.Bus BMS (high level – closing; floating or low – opening)
- Automatic reconnection: after 30 s if the voltage has increased (sign of charge); after 3 attempts – expects stable voltage ≥26 V / 52 V for 30 s
- Current consumption in off state: <4 mA
- Protection degree: IP54
Features and benefits:
- Full compatibility with VE.Bus BMS — automatic load control
- High current capacity — up to 230 A for powerful loads
- Support of high system voltage — 48 V for modern energy storage
- Protection against deep discharge without user intervention
Benefits of Cyrix-Li-load:
- Reliable operation in high current systems
- Direct integration with VE.Bus BMS for automatic protection
- Protection of batteries against critical discharge without user intervention
