CK342V12 - ±12V / 200 mA Symmetrial Regulated Power Supply (Kit)
Supply voltage: 18V AC / 200mA
Based on the 7812 and 7912 regulator ICs
This circuit offers a symmetrical DC output of ±12V / 200mA ideal for applications such as powering Op-Amp circuits. The output is fully regulated and also short-circuit protected.
You can also increase the output current handling of the circuit up to 1A by adding two heat sinks to the regulator ICs and using a transformer with higher current ranting (up to a maximum of 1A).
