KD‑210SC DC withstand‑voltage burn‑through power source is professional test equipment for DC withstand‑voltage testing and cable burn‑through tasks. It adopts full‑digital high‑frequency conversion technology with combined PFM frequency modulation and PWM pulse‑width modulation, as well as dual‑loop feedback control of voltage closed‑loop and current closed‑loop, achieving high‑precision and stable output of voltage and current. It applies super‑audio full‑bridge inversion and voltage‑doubling rectification circuits. Both low‑voltage‑side four‑tube full‑bridge MOSFET inversion and high‑voltage‑side full‑bridge rectification effectively reduce output ripple and improve overall power‑supply efficiency. Digital tube display modules show real‑time voltage and current readings intuitively. Equipped with imported multi‑turn wire‑wound potentiometers, the device delivers high resolution for voltage and current setting. Housed inside a heavy‑duty trolley case with pull rod, the unit features high mechanical strength and convenient transportation for diverse field working scenarios.
