AC Power Supply: Model 441A101
The Model 441A01 is a single-slot, CE marked, AC-line
power supply designed to fit only the extreme right slot of
the PCB Series 440 Modular Chassis. It supplies a maximum
of 45 watts of power and may be used to operate single or
multiple signal conditioning modules housed in the two-,
three-, or nine-wide standard chassis and optional auxiliary
chassis. Please note that while this unit is rated for a
maximum wattage of 45, CE requirements mandate that it
be used only up to 30 watts.
For wattage calculations, refer to the specification sheet for
the individual module. To determine power capability of
your particular set-up, add all the powers for all modules.
CE mandates that these totals must be < 30 watts.
DC Power Supply: Model 441A102
Model 441A102 is a single width, CE marked, rechargeable
DC battery power supply that can be used in place of the
441A101 AC Power. Standard accessories include:

Model 017A22 power cord

Model 488A08 battery charger

Built-in 3.0 Ah NiMH rechargeable battery
The optional Model 488A09 is a 12VDC @3.4A AC Power
Adaptor that allows the 441A102 to be used with any AC line
power in the world. (100-240VAC 50/60Hz).
The 441A102 can be used to power up to 30 watts of PCB
modular series units. For wattage calculations, refer to the
specification sheet for the individual module. To determine
power capability of your particular set-up, add all the powers

for all modules. CE mandates that these totals must be < 30
watts.

Operation

To operate, slide into the power supply slot of the PCB Series
440 Modular Chassis, tighten up the two mounting screws
and turn the power switch to ON.

The 441A102 has some components that
will get hot under heavy loads.
Do not remove the module from the
enclosures immediately after continuous
heavy use. Let completely cool first.
Charging the Battery
It is not recommended to charge the
441A102 while the power switch is ON. No
damage will occur, but charge time will
increase.
To calculate the estimated battery life, divide 30 by the total
number of watts of all the modules being used. Refer to
module specification sheets for the number of watts to use in
your calculation. To charge the battery:
1. Turn power off on the front panel of the 441A102.
2. Plug the Model 488A08 into the charger input jack.
3. The yellow charge light on the charger will light solid
during fast charge as indicated on the charger. Typical
charge time for a totally depleted battery is 1.5 to 2
hours.
4. After the battery is charged about 90%, the charge light
will begin to blink (1/8 sec blink). If possible, leave
charger on with charge light blinking for another few
hours to get maximum charge.
Remove the charger plug by pulling
on the body of the connector, not
the cord. This is a locking feature to
ensure a good connection while
charging.
