Three Phase Pre-payment Electronic Energy Meter(IC card) Major Technical Data: Name of product: Three Phase Pre-payment Electronic Energy Meter(IC card) Type: DTSY318 DSSY318 Accuracy class: 1.0 Power consumption : < 9VA Rated voltage: 3*57.7/100V 3*220/380 3*100V Rated current: 1.5(6) A 10(50) A 20(100) A Application: Three phase IC card pre-paid electronic energy meter, developed with SCM and metro- chip, can achieve the control on pre-paid power and load. It can prevent any billing delay and tamper. It is an ideal product with overload control, tamper proof, and thus makes the power commercialized. Main functions: 1. Measurement of 50Hz pre-paid three phase active power 2. Warning of remained energy and remind the user for payment 3. Set up maximum load and warning of overload and power off 4. Re-reading of consumed power, left power, cumulative power and number of prepayments for power 5. Power off when no energy in the meter 6. Transfer IC card parameter Salient Features: 1. High accuracy: 1.0 class 2. High reliability: long operating life 3. Low power consumption, tamper proof, light weight, small size and easy to install. 4. Register & display consumed power, and LED displays status of consumed power. 5. SMT technology and re-flow soldering technology is adopted. Meter has strong capability for disturbance. EMC can comply with requirement of IEC 61036-2000 6. Single phase and three phase pre-payment electronic energy meters can share one power control system so that it can facilitate the user. 7. Tamper-proof meter box can be supplied for easy installation.
