First. Main technological characteristic
High sensitivity, high overload, high dependability, burglar-proof electricity;
The IC card prepays the expense electricity, owe the fee to cut out automatically; Surplus electric consumption is not enough to call the police in order to remind users to purchase the electricity in time;
The digital tube reveals present surplus electric consumption and various power consuming states;
Counting one degree of devices reveals that adds up to the total power consumption;
Load controls the function, while exceeding the load presumed, the ammeter cuts out automatically, resume having the electricity automatically 5 minutes later; If insert and purchase the electric card, resume supplying power at once;
Adopt logic to encrypt the card and encrypt algorithms dynamically, have extremely high antifalsification and data security;

Working voltage: AC150- 250V
Standard electric current: 2.5(10) A-20( 80) A
Accuracy grade: 2.0 grades, 1.0 grades
The IC card can be wiped and written & ge of number of times; 1 million times
Three. The system makes up:
IC card type prepaid fee electric energy meter; 1 IC card / table; Sell electrical machinery and management software.
Four. External dimension:
115mm× 173mm× 67mm
