Example for operating time:
In the following examples we assume that batteries are inserted with a capacity of 1000mAh.
The batteries can be a performance of approximately 70% is removed. After that, is the voltage for
the operation of Timeboys not enough. This results in a performance of 700mAh.
Example 1 TimeboyIV with Barcode / RFID-Reader:
The input needs around 45 sec.; equal to:
45s and 100 inputs is a oper-
ating time of 1,25 h.
- Display hell
= 45 mA
- Barcode
= 86 mA
- CPU
= 8,4 mA
= 139 mA x 45 s = 6255 mAs x 100 inputs / 3600
=
175
mAh
Switch after
100
inputs from very bright (15 s) -> to (15 s)-> dimmed light, Saving mode:
- CPU
= 8,4 mA 30 s = 252 mAs
- Display hell
= 45 mA 15 s = 675 mAs
- Display gedimmt
= 5,0 mA 15 s = 75 mAs
= 1002 mAs x 100 inputs / 3600
=
28
mAh
30s switch and 100 inputs is a operating time
of 0,8 h.
Standby time (communication „off“):
- CPU Sleepmode = 2 mA x 250h
=
500
mAh
Akkuleistung:
This is a complete operating time of
227 hours.
175
mAh
+
28
mAh
+
500
mAh
= 702 mAh ~700mAh
