Static Prepayment Meter

Static Prepayment Meter
Product Detailed
DDSY93G single phase prepaid electronic meter can realize using electric power after prepayment 1. The product adopts CPU card (named as smart card) and advanced micro-electronictechnique to collect, process and memorize data. Its technical performances arecomplying with the requirements of national standards of GB/T18460.3, IEC61036and JB/T8382-1996. It has strong function of preventing the meter from decoding,compatibility as well as features of small size, weight light and high reliability2. Work principle: There are two basic function modules in the meter separately named the energy meteringmodule and the MPU controller module. The energy-metering module adopts well-selectedspecial integrated circuits as will send the pulse frequency to theMPU to accumulate the consumption of the electricity. The MPU controller moduletransfers message between the prepaid card and the port of card to realize the prepaidmetering function and other appointed functionThe working principle of DDSY93G that has basic functions is as follows: Fig 1: Working principle (skim) 3. Basic functions 3.1. Bi-directional active energy measurement 3.2. LED display or LCD display 3.3. Pulse output with optical-coupling isolated 3.4. Over-load alarm 3.5. Precaution alarm 3.6.
