Build your own industrial dual output power supply, with two fix output DC voltages (from -/+ 5VDC) and save. 

Simply connect the board to Central-Tap (CT) transformer low voltage transformer (up to 2 * 24VAC) and get positive (+V) and negative (-V) Voltages referencing to common ground on the output. 

Mount and power it--and you're in business. 

Drive your Operational Amplifier (OP-AMP) board etc. The boards will allow you to easily power all your CMOS or Op-Amp components. The Terminal Block TB connector is included and makes it easy to use. 

Starting at $46 with your output DC voltage requirements. Output voltage can be customized as needed :

+5VDC, +9VDC, +12VDC, +24VDC on the positive output & -5VDC, -9VDC, -12VDC, -24VDC

Note: Due to the regulator construction difference, use dual heat-sink (if needed), one for the LM78XX, and one to the LM79XX. Additionally, Please be advised wires and transformer are for demonstration only and sold as options
