Introduction:

The Supertex SR10 is an inductorless switching power sup-

ply controller intended for operation directly from a rectied

120/240VAC line. Due to the capacitor-coupled, switched

shunt topology (CCSS), it exhibits low standby power and

good efciency while employing no magnetics nor high volt-

age electrolytic capacitors.

To meet a wide variety of applications, the SR10DB1 is

highly congurable. Many components are socketed. Half or

full-wave rectication is jumper-selectable. Output voltage is

jumper-selectable to 3 xed voltages or may be set anywhere

in the range of 6 - 28V using an on-board feedback divider.

AC Input (H and N)

Connect to the AC line. The ‘H’ terminal should be connected

to the AC line hot conductor. The ‘N’ terminal should be con-

nected to the AC line neutral conductor. When congured for

half-wave rectication, the N terminal is connected to the DC

output minus (–) terminal.

DC Output (+ and –)

Connect the load to these terminals. Do not connect earth-

grounded loads or test equipment without using an isolation

transformer on the AC line.

Output voltage is jumper-selectable at 6, 12, or 24V, or it

may be set in the range of 6 - 28V using the RFB feedback

divider and setting the jumper to ADJ.

Notes:

1. Dependent upon conguration and degree of transient protection.
