Relay Box

from 390.00

The Relay Box provides AC power to the oxygen concentrators. A signal is sent over a coaxial cable from the HVO master to the relay box to switch power on and off as needed to pressurize the oxygen storage tank(s).

A pair of coaxial connectors are provided on each Relay Box for “daisy-chaining” to increase the number of oxygen concentrators that can be controlled.

Available in 3-outlet (US & EU) and 5-outlet (US) models.

NOTE: Each 3-outlet relay box requires a 20 amp dedicate electrical circuit, whereas each 5-outlet relay box requires a dedicate 30 amp circuit.
