The 3-4 Adapter converts a 28V 3-pin XLR Block Battery output to 15V 4-pin XLR for powering 14.4V accessories. This is especially useful when block batteries are 28V only, with no outputs for 14.4V-only accessories. Includes integrated source voltage readout.

  • Maximum continuous output current — 3A (2.7A typical)
  • Protections — soft-start limits inrush current & gradually ramps output voltage, reverse-voltage protection up to 40 V, over-current protection, short-circuit protection, & over-temperature shut off

The build quality of the items were extremely high and I was very impressed with the customer service and speed of service. I would buy off these guys again in a heart beat for all custom work.
