Although this module is designed for the LED VU Meter Kit, it has proven to be a very popular power supply for opamps and peripherals like extractor fans and relays.

Voltage regulation is based on the well known LM7xxx Series. Standard regulators supplied with the kit are for +15V, -15V and 24V, all with 1A rating. Since all LM series regulators have similar pin assignments, the PC Board can accommodate regulators with other voltages without any modification.

Power transformers (not included in Kit) of 15-0-15Vac and
0-24Vac are required for operation.
