The ubiquitous wall wart usually provides low-voltage, isolated dc output from the ac mains, but some applications need low-voltage ac, either for circuit operation or because the device it supplies will perform its own local or multivoltage regulation. A new series of Class 2 plug-in units from Foster Transformer provides outputs ranging from 9 to 24V ac, depending on model. The UL-listed transformers are rated for 10 to 50 VA; prices for a basic 10-VA model start at $3.10 (1000).
