Diversity in the B-series
Janitza B21 - 1 Phase kWh Meter
Specifically designed for 1-phase measurements, the B21 offers direct measurements up to 65 Amperes. The meter has a compact design, taking up only 2 DIN modules. With communication protocols like M-bus and Modbus, combined with its S0 interface, the B21 is the ideal choice for efficient energy management in simpler systems.
Janitza B23 - 3 Phase kWh Meter:
The B23 is optimized for 3-phase measurements, with direct registration capabilities up to 65 Amperes. It is wider than the B21 but still provides a snug fit in systems with its 4 DIN-module size. Like the B21, the B23 also features an S0 interface, making it easy to connect to energy management systems.
Janitza B24 - 3 Phase kWh Meter with CT:
The B24 is a specially designed 3-phase meter for indirect measurements, making it ideal for systems using current transformers. The B24 has a configurable current ratio and is equipped with a pulse frequency of 5000 imp/kWh.
Key features of B-series kWh meters:
