Output Noise The output noise is measured with a 10 μF tantalum capacitor and a 1.0 μF ceramic capacitor across the output. Remote ON/OFF Control The VHB150 series allows the user to switch the module on and off electronically with the remote on/off feature. The VHB150 series is available with “positive logic” or “negative logic” options.
