Din Rail Digital LCD Display Power Analyzer Three Phase Watt Hour Meter
Series of DZS81 three phase Power Meters are used for measuring and monitoring the power distribution system. This series combines the measurement, the analysis and the operation together. People can check the figure of current or voltage by using the keys on the meter, and through the interface of RS485, the meter can upload the information to an upper machine, which makes the information become clearer, and the operation become easier.
• Flexible Networking: RS485 /LoRa(433MHz)/GPRS communication mode.
• Small Size and Easy Installation: standard 35mm Din Rail
• User-friendly and Easy-to-use Interfaces: shift between Chinese-English.
• Advanced Flame-retardant Materials: accordance with security standards.
• Professional Energy Metering Chips from ADI company: accuracy up to class 0.2
• Adaption in Harsh Environment: such as dusty, electromagnetic, low-temperature environment; strong surge
withstand capability.
