16.9 Electrical Data
16.9.1 Power Supply of the ES800 System
ES800 System with ES801.1 Base Module
An ES800 Base Module (ES801.1 or ES801.1-S) is installed on the underside of an
individual module or on the underside of a module stack. The ES800 Base Module is
connected to the vehicle battery or the laboratory power supply and supplies the
ES800 system with operating voltage via the uniform system connector (see
chapter
4 on page 29).
Recommendations for Operation
For the safe and reliable operation of the ES800 module stack throughout the
entire area of application (e.g. for cold start tests), you must provide the operating
voltage in the following ranges at the connection of the ES800 Base Module
(ES801.1 or ES801.1-S):
NOTE
Load dump protection required!
Operating the ES800 system requires central load dump protection that is pro
-
tected against polarity reversal (in conjunction with an ES800 Base Module, e.g.
ES801.1) in accordance with ISO 16750-2 Test B.
Operating voltage
1)
7 V to 29 V DC (±10%)
2)
Operating voltage (typ.) 12 V DC
Max. permitted current consump-
tion for product stack
25 A
Fuse
3)
30 A / 32 V DC
1)
: Use an operating voltage that is permissible for all modules in the
product stack.
2)
: Due to the tolerance specifications of ±10%, the rating for these
products has changed. Check the product label to see which operating
voltage is valid for your product.
3)
: Only fuses of type "Littelfuse ATOF Blade Fuses", part number 0287030.PXS,
may be used. Additional information is available on the Internet:
Littelfuse.
Number of modules Operating voltage at ES801.1/ES801.1-S
1 7 V to 29 V DC
2 7 V to 29 V DC
3 7 V to 29 V DC
4 8 V to 29 V DC
5 10.5 V to 29 V DC
NOTE
The direct power supply to ETAS modules from other series at the GE and FE
interfaces was not taken into account for the recommendations.
