Our response
KNA developed an integrated training and measurement panel centered on a variable frequency drive. Protected terminals, switching devices, relay controls, indicators, and electrical meters support guided wiring, operation, measurement, and troubleshooting exercises.
Technical configuration
- 01input supply - three-phase, five-wire AC 380 V +/-10% at 50/60 Hz
- 02output supply - AC 380 V through shrouded safety terminals
- 03rated capacity - less than 1 kVA
- 04integrated training devices - VFD, switching, relay contacts, indicator lamps, and voltage/current meters
- 05safety provisions - branch protection, emergency stop, and protected connection points
Results Achieved
The system gives instructors one platform for practical VFD training while helping learners understand frequency-based speed regulation, control sequencing, measurement, and safe industrial-drive operation.
