Caution: Rechargeable Appliances
Certain chargers for small nickel cadmium batteries can be damaged if
connected to a
Cobra POWER 500W inverter
. Two particular types of equipment
are prone to this problem:
1. Small battery-operated appliances such as flashlights, razors, and night lights
that can be plugged directly into an AC receptacle to recharge.
2. Certain battery chargers for battery packs used in hand power tools. These
chargers have a WARNING label stating that dangerous voltages are present at
the battery terminals.
This problem does not occur with the vast majority of battery operated equipment. Most use a
separate charger or transformer that is plugged into the AC receptacle and produces a low voltage
output. If the label on the AC adapter or charger states that it produces a low voltage AC or DC output
(less than 30 volts), the inverter will have no problem powering the adapter safely.
Cobra 500W Output Waveform
Some very sensitive electronic equipment may not operate satisfactory on the output waveform referred
to as "modified sine wave" which this inverter is designed. It is a stepped waveform designed to have
characteristics similar to the sine wave shape of utility power. A waveform of this nature is suitable for
most AC loads (including linear and switching power suppliers used in electronic equipment, transformers
and motors).
PENTAGON PROTECTION®
Cobra power inverters provide five levels of protection:
1. Over-Temperature: Auto-shut off will occur when the safe operating temperature has
been exceeded.
2. Reverse Polarity: The inverter will not operate if connected incorrectly to the power source.
3. Over-Voltage: Auto-shutdown will occur if the DC input exceeds safe operating levels.
4. Low Voltage Alarm: The inverter will sound an alarm to indicate a low battery voltage condition.
5. Low Voltage Cutoff: The inverter will automatically shut off to prevent a dead battery condition.
