Product Advantages
● High-voltage step-up construction aligned with the 700W / 800W appliance class
● EI laminated silicon steel core: the laminated EI structure keeps core loss low and holds the magnetic circuit stable under continuous high-voltage demand.
● Copper windings on a robust bobbin: high-purity copper wiring and a sturdy bobbin cut power loss and heat build-up
● Class 220 (H) insulation: high-temperature insulation material raises the thermal safety margin during high-voltage operation.
● Heavy-duty lead wiring: pre-crimped terminals with insulated sleeves give a secure high-voltage termination that is quick to connect and easy to service.
● Compact square form factor on a metal base: the square body and pre-drilled mounting base drop into standard appliance chassis layouts and bolt down securely.
● Stable and clean power delivery: designed for stable output.
