The SPI range of pure sinewave inverters is designed specifically for low noise telecomms applications.

Snaptec Australia has introduced the SPI range of pure sinewave inverters designed specifically for low noise telecomms applications.

The SPI500 is a 500W DC/AC inverter and the SPI1000 is rated at 1000W.

The main features of these units are conduction and convection cooling, and heavy DC filtering to prevent any noise feedback on the DC input.

Snaptec SPI500 and SPI1000 inverters are filtered to meet the requirements for EN55022 Class A as a minimum.

Protection includes current limiting, short circuit protection and thermal shutdown with automatic recovery in case of continuous overload.

The SPI500 and SPI1000 are also low profile to fit into 2RU 19in rack systems.

Many of the internal components are encapsulated to increase the ruggedness and immunity to moisture, dust and vibration.

Very accurate and reliable, Snaptec SPI Series are solid state inverters incorporating a microprocessor-controlled high frequency PWM technology to generate a pure sinewave output.

Units can be customised to any input voltage ranging from 24 to 250V DC and any output voltage from 115 to 230V RMS.

Typical standard input voltage are 24, 36, 48, 72, 110, 125 and 250V.

With the pure sinewave waveform, high efficiency and low harmonic distortion, these inverters can power just abut any kind of load.

With the smart thermal management these inverters can be installed in air tight conditions, thanks to the large metal baseplate that acts as a heatsink to conduct any generated heat.

Input and output to the inverters is through screw terminal and these units can be chassis-mounted, or Snaptec can supply in 19in rack-mount trays.
