    Product Overview

    Manufactured by Aims Power.

    Product Features

    The DC to AC Pure Sine Wave Power Inverter Second Gen is an inverter for use with the S7 and S8 Series machines and humidifier by ResMed. When using an attached humidifier, the S7 and S8 series machines require the use of pure sine wave power obtained through this inverter.

    This inverter is able to convert DC power to AC power with controlled dips and peaks in power. Other inverters do not control these dips and peaks, making the machine and humidifier susceptible to power related damage. To obtain this type of the power, this inverter must be used when connected to a DC power source.

    If connecting a S8 machine to a DC source without the humidifier, the DC-12 Converter For S8 Machines may be used.

    Former Version: This is an updated, slimmer version with only one AC outlet. The former version was larger and had two AC outlets, however it is no longer available. To view product information and reviews for the former version, click here.
