Product Description:
DDSY1540 (C) Series - Electronic Single Phase Prepaid Energy Meter (Ladder Price Type)
Users transmit information such as purchase amount and electricity price to the energy meter through their user card. The energy meter deducts the amount in real time based on the electricity consumption and price. When the amount is used up, the energy meter automatically stops supplying power.
The types of electricity prices can be set as either single price or tiered price. Step by step electricity pricing refers to the calculation of fees by setting the average household electricity consumption into several tiers or pricing levels. The tiered electricity pricing mechanism can effectively suppress the phenomenon of electricity waste, guide residents to save and use electricity reasonably, and is the direction of future residential electricity reform.
Main technical features
▲ Large screen LCD display of Chinese characters, with backlight that automatically lights up when inserting cards or infrared communication.
The display range for the remaining amount and total electricity consumption can reach 999999.99kwh with eight digits.
▲ High precision electricity price, with a range of up to 99.999999 yuan/kWh.
▲ Two level alarm: The alarm amount and alarm method can be set freely. The alarm methods include sound and light alarm, and trip alarm. When an audible and visual alarm occurs, the buzzer inside the meter emits an alarm sound and the backlight flashes. When a circuit breaker alarm occurs, the power meter stops supplying power. Both types of alarms can be cancelled by inserting a user card when they occur.
▲ Overload power outage: When the average power of the user exceeds the set value, the energy meter will automatically stop supplying power, and after 5 minutes, the meter will automatically power on.
▲ Strong encryption: By using encryption cards and dynamic encryption algorithms, system data will not be decrypted.
▲ Magnetic holding relay adopts high-power magnetic holding relay, with low power consumption and high reliability.
Infrared communication facilitates user meter reading and setting of meter parameters.
▲ Built in high-precision clock.
When the monthly automatic settlement reaches the settlement date, the record of the total electricity consumption for the current month will be automatically frozen and reset to zero. Start a new tiered electricity pricing cycle. The settlement date can be freely set.
▲ It can automatically record the electricity consumption of the past 12 months.
▲ It can record the total electricity consumption since the user opened the account.
▲ It has two types of electricity prices: single electricity price and tiered electricity price, which can be switched at any time through user cards and electricity price setting cards.
The electricity price can be divided into up to four tiers, and the amount of electricity in each tier can be switched at any time through user cards and electricity price settings.
