All-In-One Power Module

All-In-One Power Module

A complete kit of parts to build an 115/230VAC to dual-regulated DC power module. The transformer has dual primary windings making it suitable for use in countries with 115VAC or 230VAC supplies. The regulator section is built around 2 x LM723 and is based on our PSU-2 design and offers a high-quality regulated supply with output ratings in excess of 450mA making it ideal for the small through to medium-sized systems

The unit can be configured* for standard +/-9V, +/-12V or +/-15V DC rails or, by careful selection of components, for other dual-rail requirements desired.

The unit measures 163mm x 100mm with a height of approximately 45mm.

Maximum ratings for the standard configurations are:

9VDC	700mA
12VDC	550mA
15VDC	450mA

Here is a picture of the +/-12V version installed in one of our 6U Euro Sub-racks

*Please note that the available range of voltages will be dictated by the transformer that has been supplied in your chosen kit. You are, for example, unlikely to get more than 11V from the 9V version of the kit.
