Din Rail-type Energy Meter
YN3000LY
Overview
The YN3000LY Three-Phase Din Rail-type Prepaid Energy Meter(Full Function 7P) is mainly used in the field of electric energy management for three-phase four-wire networks with the frequencies within the range of 45~65Hz. It can measure the electric energy information in the power grid and exchange data with the upper computer through encrypted IC cards or 485 communication. With a high-power relay built in, the instrument can perform local tripping and closing operations, thereby implementing prepayment function; users can set the internal parameters of the electric meter according to the actual situation on site; featuring convenient use, easy operation, and high accuracy, the instrument is widely used in various residential areas, smart buildings, market malls, collective dormitories, and schools.

Functional characteristics
♦ Measurement: U, I, P, Q, S, PF, F, etc
♦ Electric energy measurement: Three-phase electric energy measurement
♦ Payment control: IC card or remote payment control, payment before electricity utilization, with a relay built in for local opening and closing; the primary current is above 100A; when it is connected to CT, an external circuit breaker or contactor is required
♦ Overload protection: Real-time detection of power value; if it exceeds the threshold value, the product will automatically trip, and after the fault is eliminated and the vending card is inserted, the power supply will be restored
