Born for the Stage, Built for Industry.

    When 2000 watts of surge power are compressed into just 1.1 liters of compact space, when 94% conversion efficiency transforms every kilowatt into light and motion rather than wasted heat - this is no ordinary power supply. This is the SP-2002.

We understand the rigors of stage lighting: voltage uncertainty across global tours, continuous vibration during rigging and transport, and zero tolerance for failure mid-show. The SP-2002 tames grid harmonics with active PFC achieving PF>0.98, distinguishes transient overloads from hardware faults with intelligent tiered protection, and ensures instant ignition with 100A cold-start inrush capability.

When it leaves the stage for the factory floor - the same universal voltage compatibility, the same high-efficiency low-loss performance, the same rugged reliability - the SP-2002 remains the trusted choice for driving high-power DC loads.

Competitive Advantages

🏆 Efficiency Benchmark - 94% efficiency places this unit in the top tier of 2kW AC-DC power supplies, translating directly into lower operating costs and reduced thermal management demands.

⚡ Outstanding PFC Performance - PF>0.98 at 115V demonstrates robust active PFC circuit design with superior harmonic suppression, keeping your installation grid-friendly and standards-compliant.

🛡️ Mature Protection Strategy - The tiered protection architecture (auto-recovery hiccup mode vs. latch protection) reflects a deep, practical understanding of real-world failure modes - transient events don't kill the show, but hard faults trigger a safe shutdown.

🌍 Global Versatility - Wide voltage input (90~264V AC) plus wide frequency range (47~63Hz) means one SKU powers the world - from North American 115V rigs to European 230V industrial floors.

📦 Exceptional Power Density - Delivering 2kW from a compact ~1.1L chassis achieves a power density approaching 1.8W/cm³ - more power, less panel space.

Why employ hiccup mode for overloads and latch protection for short circuits / overvoltage?

  Overloads are often transient events - such as dimming transients in stage lighting - so automatic recovery keeps the performance running without interruption. Short circuits and overvoltage, however, typically indicate underlying hardware faults; latch protection forces a mandatory shutdown for inspection, preventing secondary or cascading damage.
