The robust, industry-standard EX-1505HMVS managed metal hub provides four screw-fitting USB 3.0 downstream ports with 15-kV ESD over-voltage protection. The EX-1505HMVS only supports self-power mode, so it is mandatory to supply the hub with power via the DC socket (+7 V to +24 V) or via the two-wire terminal strip connection (+7 V to +24 V). https://elecena.pl/product/29159374/ex-1505hmvs-usb-3-0-4-port-industrial-hub-managed-15-kv-esd 2025-07-30 https://elecena.pl/product/29159374/ex-1505hmvs-usb-3-0-4-port-industrial-hub-managed-15-kv-esd 2026-04-05
