INTELLIGENT POWER SUPPLY (FIGURE 44)
Features and Functions
The 41 OO+/UT Intelligent Power Supply can operate in three different modes:
l
Standard Power Suply with lead-acid batteries
l
Power Supply with Audio Amplifier and with lead-acid batteries
l
Power Supply without Charger (for use with 110 Ah lead-acid batteries).
Switches
The different Intelligent Power Supply modes are DIP switch selectable using the Configuration DIP Switch SWl.
The six-position DIP switch SW1 identifies the configuration of the power supply. Since the power supply employs
reverse logic, the ON switch position equals a logic ZERO, while the OFF switch position equals a logic ONE. The
normal SW1 settings for the 41 OO+/UT are listed below.
