DT1-1×100V/C (early model)
CPU: It adopts the 80C196KC(KB) single-chip 16-bit microprocessor of Inter Company, working at 12MHz main frequency, and the efficient CPU ensures that the meter can monitor and count the voltage quality of three power grids at the same time.
RAM: Use NV-SRAM with built-in high-energy lithium battery to protect data from power failure for ten years; use ferroelectric memory (FRAM), which has super features such as unlimited writing, ultra-low power consumption, and long-term data retention after power failure.
Clock chip: DS12C887 built-in high-energy lithium battery, power data protection for ten years.
Sampling circuit: Adopt high-performance single-chip true RMS conversion circuit of American AD company.
Working power supply: AC100V, connected in parallel with the first signal voltage.
Power consumption: ≤3VA.
Signal input loop power consumption: ≤0.6VA.
Clock error: ≤±1s/24h.
Dimensions: (l×b×h) 160×236×80mm; installation opening size: 150+1×70+1mm
