ES1000.3 Housing 14
When used on the road, the system has to be supplied via the ”continuous
plus” of the vehicle power supply.
Power Supplied by the ES1050.1 Battery Pack
The ES1000.3 system can be operated with an external ES1050.1 Battery Pack.
The necessary mechanical and electrical interfaces are under the top cover of
the ES1000.3.
2.3.4 Automatic Overcurrent Deactivation
The ES1000.3 Housing power supply has an automatic overcurrent deactiva-
tion. As soon as an overcurrent condition is detected for one of the output
voltages, all outputs are disabled. The V
out
LED on the front panel of the power
supply control unit goes out.
2.3.5 Remote Interface
If the ES1000.3 Power Supply is in automatic mode, the remote interface can
be used to activate/deactivate the power supply (see section 4.3.3
on page 29).
2.3.6 Service Interface
When a PC is connected to the service interface, the ES1000.3 firmware can
be updated if necessary. The service software necessary for the update can be
downloaded from the ETAS website.
The service interface is not accessible from the front but within the ES1000.3
Housing on the left on the power supply control unit directly on the circuit
board. To be able to use the service interface, you have to remove any boards
inserted next to the power supply control unit. The service interface is a serial
RS232 standard interface. You need a fully equipped null-modem cable (see
Fig. 5-8 on page 41) to connect the service interface and the PC. On the
ES1000.3 side, this cable has to have a SUB-D9 socket (female).
2.4 Fan
The housing has two thermally controlled fans. The amount of air supplied is
automatically adjusted according to the heat output of the boards and the
ambient temperature.
Note
The remote interface cannot be used to switch the ES1000.3 Power Supply
on/off during independent battery pack operation of the ES1000.3 Housing.
