The PMX-Multi series is compact multi-output isolated linear DC power supply manufactured by KIKUSUI Japan. Adopting series regulator linear topology, it delivers ultra-low ripple down to 500 μV with minimal noise, optimized for R&D testing of ICs, op-amps, sensors and semiconductors. Three models cover 2-channel PMX32-3DU, 3-channel PMX32-3TR and 4-channel PMX32-2QU, total power 200 W per unit. All channels are electrically isolated to eliminate cross-talk and support independent dual-polarity differential power output.
