Product Brief Introduction
The DDSY601type single-phase electronic prepayment watt-hour
meter(with IC card) uses a special energy measuring chipto convert the
energy signal into the pulse signal. Then the pulse signal was processed
by the microprocessor to achieve the prepayment usage and energy
The meter could offer anti-counterfeiting function, encryption
function, current limitation and cut-in or cut-off the circuit automatically.
And help the power usage department to control the prepayment
The total active power is directly displayed by LCD, LCD digital display
shows the residual electrical quantity, number of purchasing times and
the total prepaid capacity.
(1)Measure power energy and display the number with character wheel register, can calculate reverse
electricity as normal electric power;
(2)Few periphery component,simple structure,low power consumption;
(3)Adopt high reliability and long life electronic component,so the meter assumes feature of high reliability
and long life;
(4)adopts advanced microelectronics technology、large-scale integrated circuits and digital sampling
technology,do not need calibrate for long term operation
(5)One card for only one user,well protected from forgery;
(6)Auto cut-off for overload；
