AI Technical Summary
Existing mechanical and photoelectric relays suffer from mechanical wear, oxidation, arc damage, and cannot meet the design requirements of the TLN series chargers.
The charger adopts an intelligent commutator, which includes a circuit board, a switch control circuit, a protection circuit, a conductive plug and a heat sink. The conductive plug replaces the relay to realize the current commutation function, and the surface mount components and double-layer circuit board design achieve lightweight and miniaturization.
It reduces the failure rate, extends the service life, and is easy and cost-effective to install.
