Single phase Prepayment watt hour meter(WIth IC card)

Product Description

• Work principle
• There are two basic function modules in the meter separately named the energy metering module and the MPU controller module. The energy-metering module adopts well-selected special integrated circuits as will send the pules frequency to the MPU to accumulate the consumption of the electric.
• The MPU controller module transfers message between the prepaid card and the port of card to realize the prepaid metering function and other appointed function.
• The working principle of DDSY**0 that has basic functions is as follows:
• Basic functions
• 1. Bi-directional active energy measurement
• 2. LED display or LCD display
• 3. Pulse output with optical -coupling isolated
• 4. Over-load alarm
• 5. Precaution alarm
