▷Product Overview
DDSF8888 type single-phase electronic multi-rate meter (hereinafter referred to as the Meter) is the use of ASIC, the latest micro-electronics technology and SMT process design made of high-tech products. The meter has a super anti-electromagnetic interference performance, wide operating voltage range, high reliability, long life, high-precision, low-power consumption.
The power meter for measuring rated frequency 50Hz single-phase AC active energy, you can make use of infrared and RS485 communication interface to communicate with the computer; Meanwhile, the table also has a broadcasting school function for automated management of electricity power sector provides more convenient services.
The meter performance indicators in line with GB / T 17215.321-2008, GB / T 15284-2002, DL / T 645-1997 standard relevant technical requirements.

▷Features
● The meter can be set to two time zones, two sets of time table, each time the table 14 hours, 4 kinds of rates. The multi-rate electric energy parameter settings for hourly metering and automatic meter reading can be by setting the corresponding monthly data stored switching.
● Meter can record the current and last 12 months total, sharp, peak, flat, valley and positive active energy, time zone freezing positive active power, the power to run 60 0:00 Active Energy, recently slightest positive whole 96 hours to the active energy, command and control instantaneous freezing positive active energy and so on.
● LCD display for the six integer, two decimal places.
● Power cycle the required information, through significant period can be set flexibly through significant period in the range of 2-30 seconds, the default is 5 seconds.
● Meter can be real-time data exchange via infrared, RS485 and other communication with the collection terminal, collecting various power meter or meter data parameter settings.
● Meter after a power outage, you can continue to display the current total active energy meter can display the key, into a low-power state.
● Clock in the meter hardware clock circuit, and has a temperature compensation circuit to ensure that the internal clock accuracy ≤ ± 0.5s / d, the built-in clock with a calendar, timing and leap year automatic switching function.
