40 WATT SWITCHING POWER SUPPLIES
D E SCR I PTI ON
The PU40SL series of compact, open PCB constructed,
AC-DC switching power supplies are capable of delivering
40 watts of continuous output power. They operate at 85 to
264VAC input voltage without the need of voltage selection.
They are ideally suited for use in today’s CRT terminals, disc
drive systems, small microprocessor based systems and
other mixed logic applications. All models meet the safety
requirements of UL, CSA and IEC.

All multiple output models may be operated at no-load without damage. At no-load, output voltage
tolerance increases to 10%
Safety agency approvals are for the above listed models in PCB format. To order a model with a metallic
L-bracket or box, add suffix “B” for L-bracket format or “C” for enclosed format to the model number
(mechanical details shown in
page 7-1),
e.g. PU40-14SLC.

It is strongly recommended to connect the two “
marked mounting holes to system chassis
through metallic stand-offs. This helps reduce
greatly output noise.
