3 POWER SUPPLY
The power supply of the OLS300 module is provided by a rechargeable li-
ion battery having a capacity of 1700 mAh. This type of battery is mainte-
nance-free, nearly age resistant and free of the so called “memory effect”.
This effect caused rechargeable batteries of former generations to reduce the
number of possible charging cycles.
Normaly, the li-ion battery is charged by the USB-Power while the OLS300
module is connected to a switched-on USB host (notebook or PC) . Doing
so, a discharged li-ion battery will be totally charged within approx. 8 hours.
Depending on the temperature of the enviroment, the li-ion battery is able to
supply the configured OLS300 module with power for 8 to 14 hours.
The li-ion battery of the OLS300 module cannot be overcharged. Permanet
charging doesn't matter. Over- discharging the Li- ion battery is also not
possible, because an integrated protection circuit will restrain this. When the
Li-ion battery is discharged to its minimum, the protection circuit will
switch-off the OLS300 module, no matter the position of the power switch.
You can simply ‘reactivate’ the OLS300 module by connecting it to a
switched-on PC or Notebook via USB-cable.
3.1 POWER JACK
Considering the case, it becomes necessary to charge the Li-ion battery in
the fast charge mode, you can use the DC socket on the front panel, which is
according to DIN 2514. A commercial low voltage power supply with an
output voltage between 9Vand 24V can be used. Acting so, a discharged Li-
ion battery will totally charged within approx. 1.5 hours.
3.2 DISPLAY OF THE CHARGING CONDITION
The PWR/BAT- LED shows the battery condition by its lighting duration:
Long lighting means full-condition, short lighting shows nearly-empty-
condition.
You can observe the actual battery charging condition exactly when moving
the mouse cursor onto the battery symbol in the status line of the WinOLS
program.
