B-LFT 100 is especially designed to inject low frequency signals into slow control loops such as PFC regulators. To ensure maximum signal/noise in your measurements, the B-LFT 100 is capable of injecting a 1 Hz signal at the full 2 Vrms output power of Bode 100 without saturating. For your safety, B-LFT 100 features a safely isolated (600V CAT II) output.
