MSM021 3 Phase 4 Wire AC Energy Meter
2) Ten pole width (Modulus 12.5mm), complying with standard JB/T7121-1993.
3) Type S wiring (Inlet from bottom, outlet from top), use CT connect operation, may select set 27 ratio, after set the meter will direct reading when read, and haven't multiplied by rate of CT.
4) Seven digits display LCD, 5+2 digits display (99999.91 kWh, only ratio of CT when 5: 5 A) or 7digits, it is choose by ratio of CT which is set.
5) There are a polarity port of pulse output passive closed and a nonpolarity port of pulse output passive distant (the output rate is 10 kWh/pulse), ). Complying with standard IEC 62053-31 and DIN 43864.
6) Standard configuration there are a port of far infrared data communication and a port of RS485 data communication. Communication agreement complying with standard T645-1997, can also choose without function of data communication. (Product Configuration code is NC).
7) Six LED instructions respectively every power supply state, signal of closed energy impulse and distant energy impulse and data communication state.
8) Automatic detection the direction of the flow of load current. And Instructions on individual LCD
9) Single direction three components measure three phase four wire active energy consumption. It is nothing with
Direction of the flow of load current. Complying with standard IEC 62053-21.
10) Standard configuration short terminals cover, may select extension terminals cover, in order to protect to use safety. (Product Configuration code is AF).
