LRS-75-15 Switching Power Supply: Engineering Excellence for Demanding Applications

⚡ Technical Breakdown: How the LRS-75-15 Solves Modern Power Challenges

Leyu’s LRS-75-15 switching power supply redefines 15V DC reliability through hybrid LLC + SR (Synchronous Rectification) topology, achieving 94.5% peak efficiency across 30-100% load ranges. Designed for precision instrumentation, semiconductor testing, and industrial IoT networks, this unit addresses three critical industry gaps:

1. Transient Response: <100μs recovery for 50% load steps (per IEC 61000-4-29)

2. Cross Regulation: <3% deviation in multi-output configurations

3. Harmonic Mitigation: THDi <5% at full load via adaptive PFC
