Product Brief Introduction
the data exchange medium. User will load the prepaid kWh, with
settlement in terms of kWh. This meter is equipped with digital keypad
interface, which is used for active energy metering & prepayment
controlling. Besides the meter also has Infrared communication, RS485
or RF communication, metering element, real time clock unit, load
control switch and other auxiliaries.
DDZY601 model is a Single Phase Keypad Meter using kWh as settle-
ment mode. User purchases energy amount and meter will decrease the
residual energy amount gradually. When the residual quantity is zero,
meter will cut off power supply. When the residual energy is 0 or the
allowable overdraft that both sides agreed, this meter will send out
power-off signal to have load switch cut off power. The power will be
recovered automatically after inputting new purchased energy amount.
1）Measure power energy and calculate reverse electricity as normal electric power;
（2）Adopt high reliability and long life electronic component,so the meter assumes feature of high reliability
and long life;
（3）adopts advanced microelectronics technology、large-scale integrated circuits and digital sampling
technology,do not need calibrate for long term operation
（4）Prepayment mode of power consumption that is paying first, consuming later
（5）This meter adopts STS algorithm（NRS 009-6-7，NRS 009-6-8, NRS 009-6-9）and a complete safety
management system which is highly secured, and completely compatible with other STS certified systems.
（6）With function of anti-tamper that can prevent usual tamper methods
（7）With event recording function (including cover-opening event, tamper event and power failure event)
