Remote On/Off Control
The VHB75 series allows the user to switch the module on and off electronically with the remote on/off feature. Logic control
defaults to “positive” logic. The diagram shows the recommentded curcuits for positive logic. The “negative logic” option is also
available.
Output Noise
The output noise is measured with a 10uF tantalum capacitor and a 1.0uF ceramic capacitor across the output.
External Output Trimming
Output may optionally be trimmed (±10%) with external fixed resistors or an external trimpot as shown.
