3.1.9 Optional 24VDC 150 Watt Power Supplies

The HA71 Controller may be powered from 10-30VDC. However, many
applications require 24VDC power for the monitors or transmitters
providing inputs to the HA71. A 150 watt AC / DC power supply may be
included for these applications (115VAC or 230 VAC selected via slide
switch). When ordered from the factory, it is pre-wired to provide 24VDC
primary power for the HA71 controller as well as any transmitters or
monitors that may be connected by the end user.
