Digital VAF Combined Meter [SURDHI]

The SURDHI AC True RMS Digital VAF Meter (Model SDV-VAF96) is a combined electrical panel meter manufactured by Super Engineering Works that measures voltage, current, and frequency simultaneously across single-phase or three-phase networks

• Voltage & Current: ± 1.0% accuracy with automated scaling resolution
• Frequency: ± 0.1 Hz accuracy with 0.1 Hz resolution
• Measurement Type: True RMS computing, which ensures precise tracking of distorted or non-sinusoidal AC waveforms

• On-Site Ratio Configuration: You can manually program the Current Transformer (CT) and Potential Transformer (PT) ratios directly from the front panel interface.
• CT Scaling: Supports primary inputs up to 25,000A for standard /5A CT secondary ratings, or up to 5,000A for /1A secondary CT configurations.
• PT Scaling: Highly configurable with a built-in multiplier range stretching up to 5,000.
• Bonus Monitoring Metrics: Beyond simple VAF diagnostics, the software counts system Run Hours (up to 99999.9 hours) and tracks mechanical RPM motor telemetry (ranging from 80 to 10,560 RPM based on pole profiles)
