Output Noise The output noise is measured with a 10µF t ant alum cap acitor and a 1.0µF ceramic cap acitor across the output. Remote ON/OFF Control The VHB50 series allows the user to switch the module on and of f electronically with the remote on/of f feature. The VHB50 series is available with “positive logic” or “negative logic” options.
