STP-120 Power Inverter
Protective Features
The inverter monitors these conditions:
Low Battery Voltage – This condition is
harmful to the inverter, but could damage the
power source, so the inverter will automatically
shut down when the input voltage drops below
9.5 – 10.5 volts DC.
Input Voltage Too High – The inverter will
automatically shut down when the DC input
exceed 15 volts.
Thermal Shutdown – The inverter will
automatically shut down when the unit becomes
over heated.
Overload/Short circuit Protection – The
inverter will automatically shutdown when a
short circuit occurs.

The STP-120 is designed for high-efficiency
operation to provide the most output with the
least battery power usage.
Advanced protection
• Thermal Protection shuts the unit off to
guard against the unit getting too hot
• Overload Protection protects the unit from
excessive loads
• Under Voltage Protection turns the unit off
to protect the battery from being over
discharged
This Sima power inverter produces a modified
sine wave output which is suitable for most
AC loads. This includes lights, appliances,
motors, TVs and most electronics.
