The Gen3 AutoSIR (1st‑generation) is a continuous, multi‑channel Surface Insulation Resistance tester that measures (10^{6}) to (10^{14}\ \Omega), supports 1–1250 V bias (internal presets and external supply), and is configurable in 64 channel systems with fast full‑scan times (all channels in seconds).
Core OEM specifications
- Model family: Gen3 AutoSIR (1st Gen; AutoSIR / AutoSIR2 family).
- Measurement range: (10^{6}) to (10^{14}\ \Omega) (per channel).
- Applied (bias) voltage: Internal presets (0 V; 3.3 V; 5 V; 10 V; 12.5 V; 15 V; ±50 V; ±100 V) and external bias selectable from 1 V up to 100 V (typical) and up to 1250 V with external supplies/options.
- Channel configurations: 64, channels per chassis (expandable via additional racks/cards; some literature notes up to 2048 channels with system expansion).
- Measurement method: Continuous monitoring on all selected channels (no switching artifacts when bias = measurement voltage).
- Scan/measurement time: All 64 channels in <8–30 seconds depending on firmware and configuration (typical published figures: <8 s to <30 s).
- Current limiting: 1 MΩ series limiting per channel to preserve dendrite growth for failure analysis.
- Environmental monitoring: integrated temperature and humidity logging tied to test data.
- Software / OS: Windows‑based control software (AutoSIR/AutoSIR2+ GUI; supports templates, data export, graphs).
- Power / form factor: typical mains 110/230 V single‑phase; chassis dimensions and weight vary by configuration.
Functional features (what OEM emphasizes)
- Continuous measurement avoids switching transients and enables frequent sampling intervals (minimum 1 minute selectable)
- High dynamic range (up to (10^{14}\ \Omega)) for long‑term reliability and conformal‑coating testing.
- Configurable templates and standards compliance (IPC, IEC, JIS, Bellcore) built into software.
