1 Introduction
This section contains information about the basic features and applications of
the ES1392.1 High Current Switch Board. A block diagram is also included
here to show the schematic layout of the board.
1.1 Applications
The ES1392.1 High Current Switch Board is used to switch five high current
battery nodes to +UBatt (five nodes) or -UBatt (one node).
The ES1391.1 Power Supply Controller Board is used to control the ES1392.1
High Current Switch Board with TTL signals. An ES1391.1 Power Supply Con-
troller Board can control up to two ES1392.1 High Current Switch Boards and
at the same time up to two battery voltage power supplies.
Five battery nodes can be switched per voltage when two ES1392.1 High Cur-
rent Switch Boards and two power supplies (for example 12 V and 42 V) are
used.
An example of this kind of scenario is shown in Fig. 1-1.
note
Some components of the ES1392.1 High Current Switch Board may be damaged
or destroyed by electrostatic discharges. Please keep the board in its storage
package until it is installed.
The ES1392.1 High Current Switch Board should only be taken from its package,
configured and installed at a working place that is protected against static dis-
charge.
note
The components, connectors and conductors of the ES1392.1 High Current
Switch Board may carry dangerous voltages.
These voltages may even exist when the ES1392.1 is not installed in the ES4100
or ES4300 or the ES4100 or ES4300 is powered off.
Make sure that the ES1392.1 is protected against contact during operation. Dis-
connect all connections to the ES1392.1 before removing the board.
