Lodestar CL25 ВM
Description
Lodestar CL25 BM model 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 - CL25B will do its job in the best possible way. CL25B fault indicators operate independently of each other. It means that current and voltage values can be read from each phase separately.
No need in additional pole-mounted RTU device anymore. Indicators communicate with one CL25 BM device via Bluetooth radio signal, then CL25B Master communicates by GSM with KOMORSAN and transmit data to any SCADA-System via IEC 60870-5-104.
Lodestar CL25 BM 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 reconfiguration ;
- Enhanced resistance to interference conditions in the air;
- On-line monitoring is possible - devices include SMS-gateway;
- Connection to any existing SCADA easily via IEC 60870-5-104 by using KOMORSAN software.
