Propaq Encore Reference Guide 119 Welch Allyn
Power Sources
For in-hospital operation and recharging from ac mains, an ac power adapter plugs into the
monitor. Use only a Welch Allyn ac power adapter to ensure protection against risk (leakage)
current hazards.
The Propaq Encore can also be powered and recharged from a dc source (isolated from ac
mains) capable of supplying 12-28 Vdc and continuously supplying 25W.
Power Adapter Intended Use
Welch Allyn power adapters are intended to be used only with Propaq monitors, and Propaq
Encore monitors are intended to be recharged using only a Welch Allyn power adapter with
a mating plug, and rated for your ac mains.
The power adapter contains symbols on its labeling. For definitions of these symbols, see
page 11.
Caution When a transport vehicle’s battery system is used to provide input
power to the Propaq Encore, surges caused by a defect in the vehicle’s power
system may blow a fuse in the Propaq’s side panel or cause further damage to
the Propaq.
Warning Place the power adapter where it cannot fall and harm someone.
Caution Use of other than Welch Allyn power adapters with the plug rated for
your ac mains can damage or compromise the safety of the Propaq Encore
monitor and may require fuse replacement in the power adapter. Verify that
the Power Adapter is set for the proper mains voltage prior to plugging it into
the Propaq.
Do not autoclave the power adapter. Do not operate the power adapter with a
damaged case, mains power cord, or plug.
