三个阶段的电子能米

Type:DSS8888 Product number: LTM33-J1 Weight:about 1.3kg Product Brief Introduction Three-phase Electronic Watt-hour Meter is adopted latest microelectronic technology, Used to measure active electric energy of three-phase A.C whose rated frequency is 50/60Hz,Coordination meter age of positive and negative. This series Meter have two mode of cut-over: cut-over directly and cut-over by mutual inductance electronics. The performance is in conformity with the technical requirements for three-phase Electronic Watt-hour Meter stipulated in GB/T 17125.321-2008 Standard。 Function and Feature: 1. Measure three-phase active electric energy, Do not need calibrate for long-term operation; 2. Three phase power supply, Loss one(any one wire of three-wire) or two(any tow wire of four-wire)phase, uninfected measurement; 3. Wide service temperature range; 4. Assuming function of defect phase indication or voltage indication; Specification and Technical Data: 1.
