    2.4.3 Power Supply The Vecto III can be powered and charged directly from mains (90 – 300 V AC/DC) via a power factor corrected internal power supply. The Vecto III can also be powered and charged via an IEEE 802.3-2008 compliant Power over Ethernet (PoE) power supply.

  • Page 32: Figure 7: Vecto Iii Power Supply Connection

    The supply current is power factor corrected and the maximum power consumption of the Vecto III is actively limited to 12.5 VA. The Vecto III can be powered directly from 110 V 50/60 Hz VT circuits due to this low burden.

  • Page 33: Figure 8: Ethernet Ports

    Vecto III will automatically disconnect from mains if excessive current is drawn from the universal AC/DC supply input port. When this protection was activated, it needs a few minutes to cool, during which the Vecto III will not restart even with valid mains voltage.
