INTRODUCTION
Power on Board Power Inverters are geared for maintaining today's modern life while
traveling in Vans, RVs, automobiles, trucks, or vehicle that has 12 volt battery power
supply and a means to recharge those batteries. This Maxx 1500 Inverter is supplied
with:
1. On/Off switch
2. Triple Outlet
3. Dual LED indicators that indicate operation (POWER), shutdown (FAULT).
4. Cooling fan
5. A grounding terminal for electrical safety.
6. DC cable connectors
7. Internal protective circuits that include:
• Automatic overload and over-temperature shutdown (activated if AC
output exceeds maximum power)
• Automatic AC short-circuit shutdown . RED FAULT LED lit.
• Automatic low voltage audible alarm.
• Automatic low-voltage shutdown.
• Automatic high-input voltage shutdown.
Maxx1500 Series - is a state-of-the art, highly efficient DC to AC power inverter that
changes 12 volts DC from a battery to 120 volts AC, 60 Hz. With proper DC power,
it can continuously deliver up to 1500 watts AC.
All Power on Board inverters have two methods of preventing batteries from being
completely discharged. When your batteries begin to drop in voltage, the inverter
will sound an alarm. You can either turn off the inverter or leave it unattended.
Further discharge will automatically turn off the inverter. If your battery does go to
complete discharge, it's because some other appliances are drawing power from
the battery.
This Power Inverter is configured with the latest soft start technology (SST) to
improve inverter operation. Before introduction of soft-start, high startup currents
from large inductive loads could shut down the inverter. Three major features are
incorporated in SST. First, gradual output voltage ramp-up during inverter startup.
This eliminates failed cold starts under load.
Second, output that momentarily dips in voltage and quickly recovers. This eliminates
most shutdowns from momentary overloads.
This power inverter also incorporates a new cooling technology that directly benefits
our customers. The new design more efficiently cools the power transistors and
combined with soft start dramatically increases reliability and the life of the product.
