Description

Lodestar CL4 was designed for fault detection with minimum load current 4A. This is a cost-effective and reliable solution for fixing an emergency process. Lodestar CL4 supports a range of communication options, including 3G or 4G LTE communications for a high speed data transfer. Lodestar CL4 devices operate independently of each other, transmitting information about the processes in each phase.

Lodestar CL4 benefits:

• Minimum fault sensing 4A;
• Identifies temporary and permanent faults;
• Registering and storing fault information such as timestamp, event type and measured values;
• Battery status control and indication.
