Lodestar CL25B
Lodestar CL25B models is a simple solution for fault detection. Optimal factory settings allow CL25B to be used without any configurations in most cases. Just activate the device and place it on a conductor - CL25 will do its job in the best possible way.
Lodestar CL25B use radio channel and all settings can done remotely via Smartphone - no need to unmount device. For Lodestar CL25B there is a possibility to trasmit data via Communication box.
CL25B fault indicators operate independently of each other. It means that current and voltage values can be read from each phase separately.
Lodestar CL25B benefits:
• Brightest Light 360° Visibility - 3 ultra bright wide-angle LEDs provide overlapping fields of light;
• Simple installation - using a single hot stick;
• Easy to replace - no additional settings are required;
• Dynamically changing sensitivity based on a load current;
• Minimum fault sensing 25A;
• Auto-Detect Network Frequency — intellectual algorithms allow it to work in networks with frequency of 50 or 60Hz without reconguration ;
• Enhanced resistance to interference conditions in the air.
