The Best Power Inverters on the Market
Analytic Systems has been producing Pure Sinewave Inverters since 1994. Originally designed for running navigation computers on commercial and fishing vessels, the line has evolved into a range of models with power outputs from 300 to 3600 watts featuring Digital Signal Processor control. High power MosFet technology creates a low voltage Sinewave that is fed into a compact toroidal step-up transformer to produce a very clean low EMI AC output. Northrup Grumman evaluated inverters from all major manufacturers and chose the IPSi series by Analytic Systems for their Army portable command centers for precisely this reason.
Battery voltages of 12, 24, 32, 36, 48, 72 and 125 volts DC are supported, although the SPSi2400 and SPSi3600 are not available for 12 volts DC In (currents are too high) and the SPS300 does not support 125 volts DC In.
All models are available in a standard shelf mount industrial form factor and also in a more rugged MS configuration featuring military connectors for both DC In and AC Out connections along with extra ruggedization and wide temperature operation.
Using the free to download 'Power Wizard' software, the user can select output frequency, output voltage (within +/- 10 percent of the standard voltage), output frequency (50 or 60 Hz) and low voltage shutdown parameters (to match the battery voltage) from any laptop through the standard micro-usb interface.
Safety features include current limiting, short circuit protection, inrush protection (during connection to the DC source), over-temperature de-rating and shutdown and low input voltage warning and shutdown. Most models offer an Off-Line UPS options that allows external AC to be routed through the inverter for high power UPS function if the external AC fails.
We currently offer two series that are sealed to IP66 standards, the 300 watt IPS300MW and the 3000 watt IPSi3000MW. These inverters are designed for rugged mobile operating conditions where water and dust protection are required. Their waterproof construction also makes them ideal for locations where C1D2 certification is mandatory. *Note – these units are not C1D2 certified, but are suited for applications that would obtain C1D2 certification. We have many customers that put our products inside C1D2 enclosures.
