This listing is for 1 x STI G2 Rackmount power inverter. 40-72VDC in 230VAC 300VA output. This is 1.3A / 300 watts depending on the loads power factor.
As we have several of these available for sale, the item in the listing photos is not necessarily the one you will receive. If you would like additional photos or any further information, please message us and we will get back to you.
We have tested these units in our workshop to check the input voltage range, output voltage, output current, overload, alarm relays and quality of the sinewave output.
They come with a Anderson powerpole PP30 connector in a packet, all you need to do is crimp your wires on and go. The contacts will take 12-16ga cable. In the workshop we used 6mm automotive cable (4.59mm2) of copper and we had to cut 2 strands to make the cable fit. You will need to fit a suitably rated fuse or circuit breaker to the battery bank.
The inverters have rackmount ears and are only 340mm deep overall making them perfect for small communication rack installations where mains powered equipment needs to run. They have a pure sinewave output and are made in Belgium.
The tests we did on these inverters were done using a Zimmer LMG95 power meter. We are a bit limited to the amount of photos we can add to the listing, but if you would like additional photos or photos of the unit you will receive, please message us and we will send them through.
The tests shown are output voltage with no load, output with 300w of light globes, output voltage waveform with 300w of light globes

Description
The STI / G2 inverter module is an up-to-date high efficiency, high frequency switch mode DC/AC converter, especially developed for AC needs in Telecoms.
The STI / G2 offers output characteristics with full sinusoid, stable output voltage in static or dynamic conditions. A smart digital control technique allows very fast response time to any load variation, as well as good overload capabilities.
The wide input voltage range (from 40 up to 80 VDC) allows using this inverter with any Telecoms application using 48/60 VDC input.
The environmental friendly design of this range complies with European and International Telecoms
