According to ISO 7637-2:2011 and ISO 16750-2:2012, test pulses generated by automotive transient generators need to be verified under both no-load (open circuit verification) and loaded with specified loads.
The CA ISO is a resistor box containing all load resistors required to verify micro pulse and load dump generators according to international standards and manufacturer requirements.

Highlights

One single load resistor box

Includes all required load resistor values

Highly accurate resistors (+/-1%)

High temperature stability

Resistors with very low inductance

Resistor values 0.5ohm, 1ohm, 2ohm, 4ohm, 10ohm, 20ohm and 50ohm

Benefits

Selection of load resistors
The set of load resistors has been well selected in order to meet the wide range of source resistors specified in various national/international standards and vehicle manufacturer specifications.
The following load resistors are most used:
0.5 Ohm for Load Dump pulse as per numbers of manufacturer specifications.
1.0 Ohm for Load Dump pulse as per numbers of manufacturer specifications.
2.0 Ohm for pulse 2a and pulse 5 as per ISO 7637-2 and various manufacturer specifications.
4.0 Ohm for pulses 1, 2 and Load Dump pulse 5 as per various manufacturer specifications.
10.0 Ohm for pulses 1 and 2 as per ISO 7637-2 and various manufacturer specifications.
20.0 Ohm for pulse 1 as per ISO 7637-2 and various manufacturer specifications.
All load resistors are non-inductive and have a tolerance better than 1% as per standard requirements. They show sufficient power dissipation for the transient pulse energy.
