Three Phase Smart Prepayment Keypad Meter

Type:
DTSY541SR-SP36

Overview:
DTSY541SR-SP36 three phase smart prepayment keyboard meter is a new generation of smart energy meters, with stable performance, rich functions, strong anti-interference ability, and careful design in terms of convenient operation and data security. It adopts a fully sealed structure and shell, which can meet the severe high and low temperature alternating humidity and heat environment. The meter supports multiple communication methods to connect to the concentrator, such as PLC/RF, or directly using GPRS. At the same time, the meter comes with a keyboard for token input, which can also be used with CIU. It is an ideal product for commercial, industrial and residential use.
