One Charger Does It All!
Only the advanced PowerFlex® battery charging system can provide flexibility in charging your fleet of SKC personal
air sampling pumps. There is no need to carry multiple chargers for multiple pumps. PowerFlex can be used to
charge NiCad and NiMH battery packs for most SKC personal sample pumps (excluding EX and ATEX-approved
models and models containing lithium-ion [Li-Ion] batteries). Charge different pump models simultaneously on the
PowerFlex five-station charger.
The PowerFlex Advantage
Advanced Reflex Charging‡ Technology: PowerFlex applies short reverse (discharge) pulses in between charge pulses
to ease the battery into a full charge and to keep temperature and pressure build-up inside the battery to a minimum.
PowerFlex detects full charge before the battery starts into overcharge and switches immediately to a pulse trickle charge.
Reflex charging minimizes battery damage and maximizes battery life.
Time saving and Cost effective: One charger for most SKC personal pump models with NiCad or NiMH battery saves time,
money, and storage space. Charge different pump models simultaneously on the five-station PowerFlex.
* For U.S.-produced pump models only. Not compatible with EX and ATEX- approved models.

PowerFlex
Smart, Flexible Charging System for SKC Personal Sample Pumps
SKC PowerFlex is an advanced battery charging system
designed for optimal charging and performance of the
nickel-cadmium (NiCad) and nickel metal hydride (NiMH)
batteries used in SKC personal sample pumps. The fivestation PowerFlex can charge different SKC pump models
simultaneously.
Performance Profile
Dimensions:
Five-station: 4.4 x 5.5 x 1.4 in
(11.1 x 14 x 3.5 cm)
Single-station: 1.2 x 2.3 x 4.6 in
(3 x 5.8 x 11.7 cm)
Weight:
Five-station: 1.1 lbs (0.52 kg)
Single-station: 4 oz (0.1 kg)
Using PowerFlex
Pump-specific cables are used to connect battery packs to the
PowerFlex. Simply plug the appropriate cable into a PowerFlex
port and plug the other end into the appropriate pump charging
jack. An LED indicates charge mode. PowerFlex charges most
battery packs within six hours and automatically switches to
a safe pulse trickle charge when full charge is detected. Each
attached battery pack runs through an independent charge
cycle. Battery packs can be charged either attached to or
detached from the pump.
Status LEDs:
Steady red = Charging
Steady green = Trickle charge
Compatibility:
For use with U.S.-produced pump models
only: Universal XR Series Pumps (4 and
5 cell), AirChek 2000, and AirChek 52 pumps.
Not compatible with EX and ATEX-approved
models.
Charging time:
6 to 8.5 hrs. Typical charging times vary
with model, battery capacity, and level of
discharge.
Approvals:
Power supply is
for electrical
safety and is CE marked. PowerFlex is not
intended for use in hazardous locations.

About Charging NiCad/NiMH Batteries
Charging NiCad/NiMH batteries is generally accomplished by
applying constant current to the battery. Toward the end of
the charge cycle, battery voltage rises at an increasing rate,
tapers, and finally becomes negative. Most chargers sense this
voltage depression and either turn off or switch to a trickle
charge.
SKC PowerFlex Chargers use a different technology that is
new to industrial hygiene equipment batteries. Reflex
charging ‡ delivers pulses of current instead of constant
current to charge batteries. In between pulses of charging
current, PowerFlex applies short reverse pulses that discharge
the battery slightly and short pauses. This eases the battery
into a full and uniform charge and helps to prevent dramatic
increases in internal temperature and pressure that can
damage the battery and shorten its life. To prevent
overcharging, PowerFlex continuously monitors the charging
voltage curve to find the inflection point, then it quickly and
automatically switches to a safe pulsing trickle charge.
