Revenue grade Dual Source KWh meter
E3000 is a polyphase whole current ( 30A or 60 A ) digital KWh meter , with RS485 port connectivity.
Features
- Wall mounting design.
- Tested as per IS13779.
- Class 1.0s Accuracy.
- Dual source Measurement.
- Current limiting facility.
Dual source Measurement & Current Limiting Facility
- Measures KWh and KVARh from two sources like EB and DG.
- When on the alternate source Trips the load if current exceeds the desired limit.
- Reconnects automatically after 60 seconds.
- Prevents Overloading / Tripping of DG set caused due to excessive drawing of power by consumers.
- No need of external current limiters.
Applications
- Shopping Malls & Multiplexes
- Residential Townships
- Commercial Buildings
- LT industrial loads and many more.
