PSU-8 Dual-Rail Power Supply Unit

There is often the need to generate a +ve/-ve power supply from a single power supply input such as a battery or a plug-pack.

-V Rail (maximum)
DC Input (minimum)
PSU8-A
-12V @ 750mA
12VDC @ 1A
PSU8-B
-12V @ 2A
12VDC @ 5A
PSU8-C
-15V @ 600mA
15VDC @ 2.4A
PSU8-D
-15V @ 1.6A
15VDC @ 2.4A

The figures quoted for the -V rail are the maximum attainable and require a DC input supply with a minimum rating as shown. The +V rail will be equivalent to :-

'rating of input supply' - 'load drawn from -V rail'

For example, the PSU-8b running at maximum -12V loading with the recommended 5A minimum input will deliver approximately (5 - 2 =) 3A.

All outputs are filtered switching-regulator. For linearly regulated outputs you may either add a PSU-9 or consider using the PSU-10.

This small unit is suitable for mounting directly inside the unit to be powered but is also available as a small stand-alone supply
