Matching the capabilities of the FG 5620, up to ±15V and 5A can be delivered by the power amplifier module, which means that for many applications – namely for small 12V component and sub-assembly testing – the use of an external battery simulator
is unnecessary. The frequency range and bipolarity ensure that the module will find a wide range of applications. The EUT current can be measured and a program-controlled current limit can be specified. The PA 5640 also serves as a power driver for the electromagnetic coils used in magnetic field tests and as an amplifier for conducted sine wave tests. Separate current measurements for the two types of tests ensure correct control of the test conditions.
