Thank you for purchasing the Nissei Switching Power Supply. The
NS-1228 is designed to supply up to 28 amps maximum current (5 mins)
or 25 amps continuous current at 13.8 Vdc.

INSTALLATION:

Before plugging in the NS-1228 in an AC outlet make sure that the proper
input voltage is selected on the rear of the unit. Select 115 for 100/110/120
AC operation or 230 for 200/220/240 AC operation. NS-1228 is factory set
for 230V.
The loads can be connected to either the 5-way binding posts or to the
cigarette lighter socket. Note that any devices that require more than 7
amps must use the 5-Way binging post output. The cigarette lighter socket
output has a maximum output of 7 amps.

OPERATION:

The NS-1228 has a fixed output at 13.8 VDC. All you have to do is
connect the output and turn the power switch to the 'ON' Position.

FAN:

The cooling fan on the NS-1228 will operate when the unit is turned ON.
The speed of the fan varies depending on the setting of the DC output.

PROTECTION:

The NS-1228 will automatically shut off if over 30 amps of current is
drawn from its outputs. To reset, turn the unit OFF and wait 20 seconds,
