SmartEnergy solution is fully functional High- End Single Phase Static KWh Meter based On P89LPC9401 & CS5464.
1. DESIGN
Software Calibrated Meter: using Windows based software leads to ٭shorten production time and higher accuracy.
.35KV immune Design with EMI/ EMC compatibility ٭
.Low BOM cost design ٭
.Capacitive based power supply ٭
.Consumes approximately 8mA in operational mode ٭
.Battery Back up for KWH display in power down condition ٭
.Compatible with CBIP: 88, IS: 13779-1999, IEC62052-11, IEC62053-21 ٭
Instantaneous Current, Voltage, Power and frequency parameter displayed ٭on LCD.
Software Written in Higher Language (C). This leads to much optimized ٭code and easy customization as per requirements.
2. FEATURES
Adopts special large scale integrated circuit and SMT technology, with ٭advanced process and simple construction
.Active energy measuring ٭
.Solid state LCD display (Requires only LCD Glass) with backlit ٭
.Detecting tampers or fraud with LED indications ٭
.MRI communication provision with IR transmitter and receiver ٭
More than 5 years service life and high reliability due to adopting high ٭quality components
.Immediate start-up ٭
Low power consumption less than 1 Watt and VA rating low than ٭8.0 saving of more than 30% over conventional meters.
External RTC for accurate Time and Date Display as well as event log ٭
3KB of data log possible with internal flash memory. Provision for ٭external EEPROM for data storage.

4. Anti-Tamper Features
Tamper Immunity compatible with the CBIP: 88 standards ٭
Meter records correct energy with same accuracy under reverse current ٭connection with LCD icon indication.
Neutral Miss Tamper indication as well as measurement considering rated ٭voltage. Further, under this test meter starts measuring energy at very low starting current of 1.8A.
Meter records correct energy under earth load (Fault) condition with ٭indication in LCD.
Meter records energy assuming rated Voltage and maximum rated current ٭during Magnetic field detection of 0.5T.
5. LCD Display Parameter
LCD Display parameter can be customized as per the customer requirement. Auto Scroll Display
