SLLC High Frequency Resonant Transformers

Signal Transformer / Bel SLLC High Frequency Resonant Transformers are ideal for resonant converters with a 360VDC to 400VDC input voltage range for high efficiency, energy-sensitive applications within delicate higher-end products. The SLLC series offers horizontal printed circuit board (PCB) through-hole (THT) mounting in three ETD geometric platform sizes. Additional features include a low-profile design with reinforced insulation, 4kV isolation, and IEC 61558-2-16 compliance. Signal Transformer / Bel SLLC High Frequency Resonant Transformers deliver standard 12V, 24V, and 48V output voltages in power capacities of 150W, 200W, and 250W. Typical application markets include lighting, consumer, industrial, telecom, and security.
