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
“Symbols” on page 3.
Verifying proper power-adapter configuration
Prior to using the power adapter, check it for proper voltage selection by looking in the
small indicator window on the front end (by the power switch). If the number in the
window does not match your ac mains source voltage (100-120V or 200-240V), the
adapter should be reconfigured. See the illustration on page 91.
Your biomedical technician can change the voltage setting and fuses on the power adapter
and can verify that your facility is using the correct power cord.
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.
Caution Do not autoclave the power adapter. Do not operate the power adapter
with a damaged case, mains power cord, or plug.
