The KOFLOC PS-4-DC24 is a high-grade 4-channel dedicated industrial power supply unit developed and manufactured by KOFLOC (Kojima Instruments Inc., Japan). It is specifically engineered to power and support Mass Flow Controllers (MFC), Mass Flow Meters (MFM), and associated precision flow sensing instrumentation.

Utilizing an advanced switching regulator circuit, the KOFLOC PS-4-DC24 delivers a regulated DC 24V output with ultra-low ripple and noise, preventing measurement signal drift caused by electrical fluctuations in industrial grids. Featuring four dedicated output channels, it simultaneously supplies power to up to four MFC/MFM units with balanced voltage distribution. The unit incorporates comprehensive protection mechanisms including overcurrent, overvoltage, and auto-recovering short-circuit protection. Enclosed in a rugged metal housing with passive fanless heat dissipation and DIN-rail or panel mounting versatility, it offers reliable long-term performance for semiconductor cleanrooms, industrial gas mixing lines, and R&D testing setups.
