Cyrix-Li-load 24/48V-120A - Intelligent load relay for lithium batteries
Cyrix-Li-load 24/48V-120A is a microprocessor-controlled intelligent load relay for 24 V or 48 V lithium battery systems. Installed in the load circuit, it stays engaged while the control input is high and cuts power to the loads as soon as the input is left floating or pulled low.
Main features:
- Battery voltage: 24 V or 48 V, automatic detection
- Continuous/breaking current: 120 A at 24 V, 40 A at 48 V
- BMS control: VE.Bus BMS, second line of LiFePO4 protection
- Control input: engages when high, disengages when low or floating
- Re-engagement: after 30 s, maximum 3 attempts
- Protection rating: IP54
The Cyrix Battery Combiner is a microprocessor controlled heavy duty relay that automatically connects batteries in parallel when one of them has reached a pre-set voltage (indicating that the battery is being charged), and disconnects when the voltage decreases below float level (indicating that one or more batteries are being discharged). Cyrix Battery Combiners are an excellent replacement for diode isolators. The main feature is that there is virtually no voltage loss so that the output voltage of alternators or battery chargers does not need to be increased.
