DT2B/B series voltage monitoring

CPU: It adopts the 80C39 single-chip eight-bit microprocessor of Inter Company, working at 4MHz frequency.
Data protection: Green environmental protection type 1300mAh nickel hydrogen battery pack is adopted.
Sampling circuit: Adopt high-performance single-chip true RMS conversion circuit of American AD company.
Monitoring circuit: two-way.
Working power supply: AC220V, 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) 220×230×93mm.
Full moon (day) automatically prints out all month (day) statistics.
The instantaneous value of each channel is automatically printed on the hour.
Typical daily parameters (5, 15, 25) are automatically printed or printed at any time the current month (day), last month (day) statistical parameter values.
The recording time will be printed automatically when the power fails and the incoming call.
You can print out the time when the monitored circuit has been out of power for the last 18 times.

This specification model has been discontinued, and an alternative model: DT1/C can be used.
