Modes of Operation
- Measurement Mode
- Provides Output Voltage and Output Current terminals for measurement via an oscilloscope.
- Switch under test remains in ON position.
- Load is switched on at 900 ± 5 phase-angle with necessary control provisions.
- Digital oscilloscope measures and displays Ipeak.
- I²t is calculated and displayed via software.
- Normal Operation Mode
- Provides suitable terminals for measuring Output Voltage and Output Current.
- SBL Load Adjustments: Resistance (R2) and capacitance (C) adjustments allow tuning to achieve desired Ipeak and I²t values.
