Power Grid Applications
From dispatch, distribution automation and electricity data acquisition master stations, to substation protection relays, measurement and control units, merging units and intelligent terminals, to distribution DTU / FTU / TTU and, on the consumption side, concentrators, smart meters and HPLC dual-mode communication, plus new power system connections such as distributed PV, energy storage and EV chargers. VOOHU LAN transformers, optical ports, current transformers, isolated-power magnetics and protection devices cover every kind of terminal from the station-level network down to transformer-area data acquisition.

Component-level reference designs
Component-level reference boards built by VOOHU FAEs for typical devices. Each board marks every component position, its function and the VOOHU part numbers available, so you can review selection notes and packages position by position.
