Smart DC Remote Power Supply
The HySecurity Smart DC Remote Power Supply provides an optional power
source for Smart DC gate operators that are configured for solar-power. The kit
converts high voltage AC power into low voltage DC power which eliminates the
need for solar panels. Low voltage wire is run out to the gate operator while the
power supply remains in garage or shed plugged into the AC power source.
NOTE:
To install the Smart DC operator on site, follow the separate installation
instructions that accompany the gate operator.
To install the Smart DC Remote Power Supply, review the illustrations and the
steps found on the following pages.
