DDSY23S single-phase split type code prepaid energy meter

summary:
DDSY23S single-phase split type code prepaid energy meter is an active energy metering instrument that uses digital media as the information exchange medium, and users load pre purchased electricity to settle electricity consumption based on electricity consumption. Equipped with a numeric keypad interface, it realizes the measurement and prepayment control functions of active energy. The measurement and monitoring parts are connected through a two-wire current loop. The metering section includes metering units, real-time clock units, load switches, and other auxiliary devices. The monitoring part includes a numeric keypad interface and display.

Function:
When the remaining power is zero or the agreed upon overdrawn power, a power-off signal can be sent to control the load switch to automatically cut off. Automatically restore after inputting newly purchased electricity
Has automatic detection function
Power outage event recording function.
Reverse electricity consumption is measured based on forward electricity consumption
Need calculation function
Can achieve load detection and control functions for electricity users
Applicable conditions:
Working temperature: -25 ℃~+70 ℃, storage temperature: -40 ℃~+70 ℃, maximum relative humidity: ≤ 95%
Working voltage range:
0.70Un~1.30Un. The prepaid meter works completely normally within this operating voltage range
