Power Supply
The Trident X2's internal transmitter
power supply is capable of supplying
24 VDC @ 200 mA to power the
transmitter and other devices such as
the Light / Horn. The following table
illustrates how much of this current is
required to drive various Light / Horns.
If more current is needed, then
consider the PDA1024-01.
