PSU-5 12V SLA Battery to +/-12V Supply

The PSU-5 is designed to run from a 12V SLA (Sealed Lead Acid) Battery and generates +/-12V Power rails making an ideal solution to powering your system out in the field.

Two build options exist for the PSU-5:

Linearly regulated

Maximum +12V loading
MGS15 - 1A
MGS30 - 1.5A
Maximum -12V loading
MGS15 - 1A
MGS30 - 1.5A
Load Regulation
20mV typical
Ripple
36mV typical

The outputs are post linearly regulated providing improved line noise and ripple

but the MGS30 is limited to 1.5A per rail.

Non linearly regulated

Maximum +12V loading
MGS15 - 1.3A
MGS30 - 2.5A
Maximum -12V loading
MGS15 - 1.3A
MGS30 - 2.5A
Load Regulation
48mV maximum
Ripple
100mVp-p maximum

The outputs are not post regulated which allows for higher output loading capacities.

PCB Dimensions
152mm x 76mm (6" x 3")
