OPERATING VOLTAGE
7.5 to 20 Volts DC
OUTPUTS
High Side Drivers
Vmain @ 0.5 amp (source)
Low Side Drivers
Ground @ 0.5 amp (sink)
ISOLATED BATTERY INPUT
0 to 20 Volts DC
TRANSIENT SUPPRESSION
Outputs are protected against thermal overload, direct shorts and transient
spikes from -50 to 60 Volts DC.
LOAD CONTROL
Loads will be sequenced on whenever the Master Switch is activated.
The System Manager will control loads and the high idle function only when
the Load Manage Enable input (terminal #11) is active.
Loads are shed from lowest priority to highest priority, T-1 to T-7, unless SW1
switch 2 is turned ON. Then they shed T-7 to T-1.
The voltage points are respectively:
Shed
Unshed
SW1-2
T1
12.4
12.8
T7
T2
12.2

If SW1 switch 2 is ON, then the order is reversed as shown in SW1-2 column.
If SW1 switch 4 is ON, then T1 and T2 will not shed.
Voltage must drop below the shed point for 60 seconds for a load to shed and
voltage must be above the shed point for 600 seconds for a shed load to
unshed.
MANUAL RESET
Toggling the Master Switch off for more than 2 seconds will cycle all loads off.
The system will return to normal operation when the Master Switch is toggled
back to the on position.
