Electrical
Rated input 12V to 28V DC, 22 W max, current is inversely proportional to input voltage.
Rated fuse (externally accessible) 3A, 250V, 2AG size, type T3A.
Rated output to cradle connector Monitor power = 2 Adc max @ 8.2V - 8.6V, depending on the battery charge level.
(See Charge Scheme, below.)
Charge scheme Constant current ≈ 900 mA.
Constant current for preconditioning ≈ 180 mA for pack voltage of 4.3V - 6.2V.
Constant voltage = 8.4V ± 0.06V total at the battery cells.
Charge termination triggers Charge current ≈ 90 mA.
Total charge timeout ≈ 4 hours.
Precondition charge timeout ≈ 1 hour.
Charge time (with monitor on or off) ≤ 3 hours typical for battery fully discharged but not exhausted.
The cradle can precondition most exhausted batteries, which adds to the total
charge time.
Charging terminates when the battery is fully charged or when a fault is
detected.
Charge time required on a dead
battery before NIBP can be used.
NIBP can be used as soon as monitor is powered by the cradle.
Output overcurrent Electronic overload protection. If overload occurs, monitor must be removed and
reinserted to reset the charger.

Status Indicators
Status light yellow Battery or cradle fault (time out, temperature out of range, a cell is overcharged,
cradle latch button is pressed, monitor not seated in the cradle, overload, no
battery or nonrejuvenatable battery in monitor.)
Status light green Monitor connected and battery charging
Status light off Monitor not connected, or monitor connected and battery fully charged
Power light green DC input power is being applied to the cradle.
Both lights off Cradle not powered, cradle fuse is blown, or cradle has shut itself down.
