major function

● Telemetry: Provides three-phase voltage and power factor after switching between two power sources, and provides three-phase current, active power, reactive power, apparent power, active electricity, and reactive electricity of both input and all output circuits respectively. It also measures the number of branches (it has 12 single-phase or 4 three-phase channels and can be extended to other signal instruments through internal RS485 interface to achieve multi-channel energy acquisition); All circuits have functions such as total power consumption, municipal power consumption, oil and electricity consumption, and phase separated power statistics.

● Remote signaling: ATS switch working status (detecting whether there is power on the live line of the mains), mains/oil engine power supply status, mains power outage alarm, mains power phase loss alarm, SPD normal/failure alarm, three-phase voltage limit exceeding alarm, three-phase current limit exceeding alarm; Implement equivalent detection of all input and output circuit breaker switch states for 12 AC220V live wire signals through an external expansion module.

● Display: Equipped with a 160 * 160 dot matrix LCD display, it can perform functions such as parameter query, setting, alarm information, manual switch control, manual debugging and zeroing; The CT range, transformation ratio, and penetration direction can be set on the panel.

Accuracy requirements for smart meters and their energy detection devices in AC distribution boxes: voltage, current, power, active power level 0.5, reactive power level 1.

● It has 48 types of alarms associated with relays, and the alarm information can be synchronously uploaded as messages.
