Product Introduction:The UHV series programmable automatic impulse voltage tester performs dielectric strength (high-voltage impulse) tests for safety certification and production inspection of EV chargers, photovoltaic equipment, low-voltage switchgear, circuit protection devices, energy meters, motors, cables and RCDs. It is suitable as designated inspection equipment for CCC certification of low-voltage switchgear manufacturers.
Applications- Type and production dielectric tests for low-voltage switchgear and components (including CCC workflows).
- Safety and dielectric testing for EV charging stations and chargers.
- Impulse testing for photovoltaic and renewable-energy equipment.
- High-voltage pulse tests for meters, motors, cables and circuit protection devices.
- Verification and performance checks of RCDs and residual-current protective devices.
