1Introduction
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.
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 discharge.
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. Disconnect all connections to the ES1392.1 before removing 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 Controller 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 Current 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.

Battery Voltages
The ES1392.1 High Current Switch Board does not have a VMEbus interface it is controlled by TTL signals which have to be connected to a front-facing
connector. In the LabCar environment, these TTL signals are generated by the
ES1391.1 Power Supply Controller Board which communicates with the backplane of the ES4100 or ES4300 Signal Box via a VMEbus interface.
1.2 Features
The ES1392.1 High Current Switch Board has the following features:
• Two high current switches for currents of up to 20 A
– Switch 0 switches to +UBatt or -UBatt
– Switch 1 switches to +UBatt
• Three high current switches for currents of up to 12 A
– Switches 2 - 4 switch to +UBatt
Introduction6
• Maximum overall current of 40 A
• Input voltage range of 6 - 60 V
• Control connector on the front panel ("CTRL") (digital TTL signals)
• Power supply input on the front panel
• Overcurrent protection
• Overcurrent status is routed to the "CTRL" status output on the front panel
• Versioning information (version/type of board) available via front-facing
"CTRL" connector (1-Wire
®
)
• Supply voltages are routed to the front panel ("SUPPLY")
(+5 V (2 A), +12 V (1,5 A), -12 V (1,5 A))

2.1 Functional Description
The ES1392.1 High Current Switch Board has two groups of switch channels
which differ in terms of their maximum current rating. Battery node 0 can be
switched to either +UBatt or -UBatt whereas the other battery nodes can only
be switched to +UBatt (see Tab. 2-1).
