under-voltage lockout, output short-circuit
protection, overcurrent protection, and
thermal shutdown
The USB K
eystone
C
harger fits all standard
telecommunications wall plates.
1. Connect a 9~24 VDC power supply to the
input power terminals using 18~24 AWG wire
.
Daisy chain multiple chargers if desired.
2. Snap the charger into the wall plate from the
back.
3. Check clearance behind adapter to ensure
space for proper bend-radius of cables.
4. Check to see that the LED power indicator is
lit and connect a USB device to
be charged.

200ft (61m) max.**
50ft (15m)* 70ft (21m)* 80ft (24m)*
NOTE
S
:
1. The maximum distance shown above is dependent on the wire gauge, number of wires
used, types of devices connected, number of devices connected, and power supply.
2. For a 12VDC/5A power supply, maximum distance** can be calculated with 1200ft/x,
where "x" is the total current draw of the connected devices. For example, if three
5VDC/1A devices are connected, then maximum distance is 1,200ft/3 = 400ft (122m).
3. The maximum number of devices that can be connected to a 12VDC/5A power supply is
three 5VDC/2A devices or six 5VDC/1A devices.
*Arbitrary distances for illustrative purposes only.
**Using all 4 pairs of a Cat6 cable.
