Single phase local tariff control smart meter
【Overview】
Adopting advanced integrated circuit design and manufactured with
advanced SMT and re-flow soldering technology, single phase local
tariff control smart meter DDZY***2C-Z has the features of
accuracy, high overload, low power consumption and strong
capability of resisting disturbance. And the meter was equipped
with infrared palmtop, RS**5, power line carrier communication
connection, which can ensure the customer program, timing and
reading the meter by themselves. 【Function
overview】 * Store the latest *2
months active power forward direction overall, peak, smooth, valley
electric quantity and active power total electric
quantity. * Save latest *2
hours null point freeze data and *6 integral point freeze data;
save latest 2 time zones, time interval records and appointed
freeze record; save latest 3 instant freeze
records. * Broadcast
timing function: the gap between electric meter clock and timing
clock within 5 minutes can broadcast timing; otherwise the electric
meter would not response. Broadcast timing can check once per
day. * Built-in clock
chip, multi-tariff, which can support *4 time
intervals. * Events
recording function: record program, timing, reset, open meter
cover, power down, switch out, switch on
recording. * Automatic
settling account function: can set the settling account by
management system. * Freeze
function: freeze at fixed time, instant freeze, convention freeze,
daily freeze, integral point freeze * Tariff control
smart: the electric meter has time division electrovalence and
stepwise tariff, which can switch over by the
setup. * Alarm
function: set up the alarm amount to remind the user to purchase
electricity in time, preventing the unnecessary troublesome to
users. * Overdraw
function: after user consumed the purchased amount but hasn’t
purchase more in time, he is allowed to overdraw some
amount. * Preventing
corner function: when the electric meter balance amount is more or
equal to the recharge threshold amount, it won’t allow this
purchased amount. * Remote power
on & outage control function. * Problem self
test function. * Battery under
voltage test function. * Have the auto
cycle display status and keypad page turning display
status. * Have backlight
big screen character suggestive LCD display. * Can display
when power out and activation by the page turning
key. *
Telecommunication function: infrared, RS**5 and power line carrier
telecommunication function.
