TripleRegulated EI38 supply

Triple regulated supply using EI-38 transformers:

• Size: 100x90 mm
• Two 4VA EI38 pcb transformers (default 230VAC primary, 2x7.5V secondary and 2x9V secondary)
• Dual regulated + single regulated output voltage (default 5V single, +/- 9V dual)
• Typical max output current (0.5A @ 5V, 0.2A @ +/- 9V)
• LM317/337 voltage regulators for low noise output
• Various applications: Preamplifier, DAC, etc

This product is available with the following options:

• PCB only
• Complete kit with all components
• Kit without transformers
• Optionally, parts can be mounted and tested

With the default components in the kit it gives 5V single output and +/-9V dual output, which makes it suitable for the CS4398 DAC. Different output voltages can be achieved by varying transformer voltage and resistor values (see schematic).

Important: Due to the size of the transformers, the kit can not be sent using bubble envelope, so it is required to select package shipping!!

The full list of components can be found in the mounting instructions below. Note that the kit can also be supplied with different capacitor, resistor and transformer values, let me know what you need:
