Wiring
Two basic circuits typically connect to the HandPunch:
•
•
Power Input
•
HandPunch to Host Computer
-
-
RS-232
-
modem
The minimum wire size for these circuits is AWG 22; the maximum is AWG 18.
2.3.1
Power Input
The HandPunch uses an internal switching regulator to obtain internal operational
power. It accepts input voltages from 12 to 24 VDC or 12 to 24 VAC at 50 to 60 Hz.
The HandPunch comes with a 120 VAC to 13.5 VDC power supply (Class 2, Model
No. P48131000A010G – 120 VAC, 60 Hz, 21 W, 13.5 VDC output @ 1000mA). An
optional 220 VAC to 13.5 VDC power supply is also available.

optional 220 VAC to 13.5 VDC power supply is also available.
To power the HandPunch with this power supply, a 120 VAC (or 220 VAC as
applicable) duplex outlet must be within 5 feet of the HandPunch. The power supply
has a 6-foot cable to provide a comfortable reach between power outlet and
HandPunch. The barrel jack at the end of the power supply’s cable is connected to J12
on the HandPunch PCB.

Do not connect a HandPunch’s power supply to a switched duplex outlet. The
HandPunch must have a constant source of power for proper operation.

Battery Backup Operation
An optional power-fail protection circuit board can be attached to the main circuit
board to provide and control battery backup. The battery backup option uses a 12 volt
800 ma/hour sealed lead acid battery to provide backup battery power. This battery is
located immediately inside the rear panel of the HandPunch and plugs into jack J4 on
the keypad control circuit board located in the top of the chassis.

The design of the HandPunch’s internal power supply is such that any range of the
above input voltages may be used and still provide proper battery charge voltage and
battery backup operation. Switch-over to battery power is automatic and occurs when
the input voltage falls to approximately 10.5 volts. At that time the backup battery
charger is disabled to save power, and uninterrupted operation continues on battery
power.

battery backup operation. Switch-over to battery power is automatic and occurs when
the input voltage falls to approximately 10.5 volts. At that time the backup battery
charger is disabled to save power, and uninterrupted operation continues on battery
power.
When input power is restored, the HandPunch switches off of battery operation and
the battery charger is re-enabled to recharge the battery. Battery charge voltage is set at
approximately 13.65 volts, and battery charge current is limited to approximately 50
mA. A fully discharged battery requires approximately 12 hours of charge to fully
recover.
