Optimal coverage and energy, when used on planting beds, requires the use of bars mounted side by side and end to end. With each bar 2
1/2" wide and 21" long, this layout puts bars on 3" centers with ends touching. The bars have a DC power connector on each end that allows
power to flow through the bar for connection to another bar. The limit on this "chaining" is 4 bars in a series.
There are a wide variety of power supplies available for use in chaining. For simple setups, you can just swap out the wall plug supplies for a
single large supply without any additional cost. For larger setups, LED Grow Master can provide large supplies that will power many strings of
4 bars easily. Most of these power supplies will work on both 120vac and 240vac. When operated on 240vac, the cost of operation drops
about 40% over the same setup running on 120vac.
LED Grow Master supplies commercial power supplies for larger setups. Our best value unit is 960 watts, which is about 100 Pro-5 bars. It's
light weight and electronic. Power supplies are available in either shelf mount or DIN mount. Keep in mind that when powering bars for
commercial use, it is recommended that a maximum of 4 bars be used per power drop. The use of automotive or high-voltage cable type 00
is recommended also. We do not supply this cable because it is always less expensive for the grower to purchase it locally from an electrical
supply house. The "Aluminum Multi Conductor Parallel & Tee Tap Connectors" pictured on the below are recommended for tapping into the
buss cables. (positive or negative).
Commercial growers "should" use 3-phase power. The commercial power supplies we feature are 92% efficient, compared to only 80% for
single-phase type units. Efficiency relates to how much energy is lost during the convert from AC to DC, something which most commercial
growers are sensitive to. Ideally, one should run our products on photovoltaic or wind power, as our products are the only plant growing option
for operating off the grid. More options are available if you would like to run "off the grid" using solar/battery setups.
For larger commercial setups requiring 1000 or more bars you have the option of special bar to bar cables as well as engineering drawings
needed to show bar mounting and power drops.
