Conclusion
Using the VIPer in the buck mode has its benefits for appliances and other industrial
equipment which require a reference to neutral. For currents up to 350 mA and voltages
greater than 10 V, it is beneficial to use this inexpensive power supply. The cost savings
compared to a transformer, opto-coupler, and low parts count, makes this solution very
attractive.
