adopting advanced microelectronics, lsic, digital processing technology and smt technics, ournewly developed dds1661din rail mounted three phase kwh meter utterly conform to the relative technic requirement of grade 1 single phase kwh meter of iec 62053-21. it can precisely calculate the active energy loss of rp 50hz or 60hz three phase ac network. reliable, small size, light, gorgeous and easy installation, it is widely-used and convenient collaborating.
features:
1. start current
transformer operated:active1.0meter display 0.002ib
direct connected:active1.0meter display0.004ib
2. creeping
when voltage circuit is 115% rated voltage and current circuit has no current, test output should not be more than one pulse.
3. loss
voltage circuit loss≤1.5w/5va, current circuit loss ≤2va
4. working voltage
normal working voltage :0.9~1.1rated voltage
maximum working voltage :0.7~1.2rated voltage
5. working temperature
standared working temperature -25ºc~+55ºc
maximum working temperature -40ºc~+70ºc annual average relative humidity:≤75%
6.safety
fully conform to gb/t 17215.321-2008grade 1 and 2 static ac active energy meterand gb/t 17215.323-2008grade 2 and 3 static ac reactive energy meter
