HY-ZSU (HY-Z) adopts lightweight SiC high-frequency topology, ultra-compact 1/6U chassis dimension 70(W)×349(D)×83.25(H)mm, single unit weight only 2kg with anti-slip base, portable for field testing, and stackable in 19-inch rack trays for high-density multi-channel systems, supporting far more channels per cabinet than HY-G half-width models.

Four power grades: 200W/400W/600W/800W, output range 10~650V, 0.32~72A. Flexible expansion: max 2 units series for higher voltage, 2~6 circulation-free master-slave parallel for higher current; each channel independent control without cross-interference for synchronous multi-channel test. Built-in active PFC with PF ≥0.99, universal wide AC input 85~265VAC stable under global grid voltage, high efficiency with low facility power consumption & grid harmonics.
