Test / endurance tests
The most important application of the AF10 with our customers is certainly the area of tests and endurance tests. The PWM generator is suitable for testing all electronics with a PWM interface, which is still in widespread use in automotive construction. In combination with the programmable ramp generator an arbitrary number of PWM traces can be realized, which can then be repeated for several months.
For control units with a high-resistance pull-up/open drain input the AF10 is particularly suitable if used with the 8-channel PWM extension available as an option. This offers eight open drain outputs on the back of the unit, with which eight DUTs (devices under test) can be simultaneously controlled.
However, also DC motors and other actuators controlled by PWM can be directly tested with the AF10. If the internal half-bridge with the 1 A output is not sufficient, also larger actuators can be operated with the external power modules available as an option.
With the H-bridge which will be available soon, also motors for example can then be rotated forwards and backwards (duty cycle from -100 % to +100 %), which can be very helpful for a wear test.
There is no limit to the use of devices controlled with PWM. Here is a speculative list of possible DUTs:
- Electrical actuators
- Magnetic valves
