AT180G-YF Three Phase Din Rail Prepaid Meter is a new generation of smart three-phase electronic energy meter. It meets the technical requirements of accuracy class 1of the IEC62053-21 standard for energy meter. It has a complete prepayment management system for energy sales management. The meter automatically deducts credit according to the electricity consumption. The recharge operation can be done remotely without any media like IC card. The meter has a two-level balance alarm function and an emergency credit function. The electricity supply will be automatically cut off when the user credit turns to zero, or reaches a preset value. It has RS485 communication interface and supports RS485 (9600 bps) high speed communication function, which is ideal for electric energy monitoring.
AT180G-YF series are featured in multi-function, multi-purpose, high stability and long life, which are suitable for real-time power monitoring system.
The meter has 1 pulse output, and the pulse constant, pulse width and output unit can be set.
