SMIV series voltage transducer is an AC voltage measuring instrument with high measurement accuracy, wide measurement range and wide application in the fields of power, chemical, oilfield, metallurgy, automatic control and other fields that need power measurement and control.
The SanMeng SMIV series includes a wide range of voltage transmitters for AC, DC, true‑RMS, mean‑value and dual‑output applications. Each model provides isolated, standard‑compliant current or voltage outputs and is designed for DIN‑rail or screw‑mount installation.
The manual offers selection tables, wiring diagrams, electrical specifications, and installation guidelines for all SMIV variants, helping users choose the right range, power supply and output configuration for industrial measurement tasks. This manual is written in Chinese.
| Standard measurement ranges (AC) | 50 mV‑20 kV (multiple steps) |
|---|---|
| Supply voltage (AC models) | 220 V AC |
| Output signal | 4‑20 mA (current) or 0‑20 mA / 1‑5 V etc. |
| Response time (AC) | ≤ 300 ms |
| Isolation | Primary and secondary high isolation |
| Installation method | 35 mm DIN rail or screw mounting |
| Accuracy class | 0.1, 0.2, 0.5 |
| DC measurement range | 0.1 mV‑50 kV selectable |
| Frequency bandwidth (DC) | 0‑5 kHz (baseband), up to 200 kHz (wideband) |
| Response time (DC) | ≤ 5 µs |
The transmitters output an international standard current (4‑20 mA) or voltage signal that is independent of the load.
They can be mounted on a 35 mm DIN rail or with screw mounting, depending on the model.
The AC transmitters have a response time of 300 ms or less.
The DC series can measure from 0.1 mV up to 50 kV, selectable by model.
