B-WIT 100 Wideband Injection Transformer

The B-WIT 100: One injection transformer for all applications.

The B-WIT 100 combines a wide frequency range (1Hz - 10 MHz) with a 600V CAT II compliant output. The wide frequency range ensures that the B-WIT 100 can be used for the analysis of very slow control loops ( low loop bandwidth) as well as very fast control  loops (high loop bandwidth). The 600V CAT II compliant output ensures that DC/DC converters with an output voltage ranging from a few volts up to mains voltage can be analyzed.

Key features
