Model DEM091PB single phase electronic prepayment front board installed active energy meter is a kind of single phase two wire active energy meter which purchase electricity by IC card, electric energy measuring, load control and using electricity management. The meter completely accord with relevant technical requirements of class 1 single phase active energy meter stipulated in internation standard IEC 62053-21. It can accurately and directly measure 50Hz or 60Hz active energy consumption from single phase AC electricity net, it is use install in meter box indoor or out door This meter has LCD monitors shows active energy. It has following features: Good reliability, light weight, specious nice appearance, convenient installation, etc.
--Standard configuration one meter with one card, can repeat input money from PC
machine which with IC programmer, may select one-time recharge card. (Please
specified when ordering).
--It has IC card with code and data against false, standard configuration use storage IC
card, may select non-contact RF card. (Product Configuration code is PJ)
--Standard configuration payment by kWh, may select payment by money. (Please specified
when ordering).
--Standard configuration of the prepayment management system use of single version,
may select network version.(Please specified when ordering).
--It has load control and function of automatic fault detection and instructions, standard
configuration without function of open terminals cover and detection, may select open
terminals cover and cut power. (Please specified when ordering).

(Product Configuration code is QB).
--A port of pulse output passive closed (polarity), complying with standard IEC 62053-31
and standard DIN 43864.
--Two LED instructions signal of power impulse (red) and direction of the trend of load
current (yellow).
--Automatic detect the direction of the trend of load current. When the yellow LED display,
that is meaning the current reverse.
--Single direction single component measure single phase two wire active energy
consumption. It is nothing with direction of the trend of load current. Complying with
standard IEC 62053-21.
--Direct connect and use, there are two types you may select. Standard configuration type 1B
connection, may select type 1A connection (Product Configuration code is PA).
--Front board two fixed holes installation, standard configuration short terminals cover, may
select extended terminals cover, in order to protect to use electricity safely. (Product
Configuration code is PD).
