Thyristor Battery Chargers - DNS POWER SYSTEMS

Thyristor Battery Chargers are engineered to deliver reliable battery charging, clean energy, and secure power backup for critical DC loads. They provide uninterrupted power to essential infrastructure, including telecommunication equipment, substations, transformer centers, emergency lighting, and advanced security systems. Thanks to their heavy-duty, transformer-based design, these units ensure an exceptionally long operational lifetime, minimal maintenance requirements, and flawless performance even in the harshest industrial conditions.

DNS Rectifiers come equipped with comprehensive protection systems, including DC leakage and earth fault safeguards. To fit your facility’s spatial requirements, charger enclosures can be custom-manufactured either with integrated or separate battery compartments. The systems offer fully selectable float and boost voltage levels, and support parallel redundant configuration for up to 8 units to maximize system reliability.
