1.1
Applications
The ES4455.1 Load Board is a carrier board for accommodating two modules
(each with two channels) for simulating high-current loads (to 90 V and to
20 A), such as injection loads.
In the ES4408.1 Load Chassis there are three 14 HP slots for accommodating
ES4455.1 Load Boards or pre-assembled variants (see "“Pre-Assembled
Solutions” with Integrated Load Modules" on page 8).
When fully assembled, the injection loads of a 12-cylinder engine can be
simulated.
1.2
Features
The ES4455.1 Load Board has the following features:
• 3 U plug-in board (14 HP, 3400 mm x 100 mm)
• Four channels for load simulations to 20 A
• Four galvanically isolated analog or digital channels for current
measuring
• Four galvanically isolated analog channels for voltage measuring
• To date, modules for the Bosch Common Rail System (two modules
each with two loads) and Bosch GDI (two modules each with two
loads) are available
