The TESTO 0554 1096 is a dedicated power supply designed for use with the Testo 330 series combustion analyzers. It accepts a wide-range AC input of 100 to 240 volts AC, making it compatible with standard North American and international mains voltages, and delivers a regulated 6.3 volts DC output to power the analyzer. HVAC technicians and combustion specialists rely on this accessory to operate their Testo 330 instruments from a fixed power source during extended service calls or bench diagnostics, reducing dependence on battery power.
This power supply is suited for residential and light commercial combustion analysis work where technicians need a reliable AC-powered source for the Testo 330 analyzer. It is appropriate for use in any setting with access to a standard wall outlet, including boiler rooms, mechanical rooms, and service bays. Its wide input voltage range makes it a practical option for technicians who work across different site conditions or travel internationally.
Designed for use with the Testo 330 series combustion analyzers as a direct OEM-style power supply replacement.
This accessory is typically connected by HVAC or combustion technicians familiar with the Testo 330 analyzer platform. Before connecting or disconnecting the power supply, ensure the analyzer is powered off. Plug the DC output connector securely into the analyzer's power input port before connecting the AC plug to the wall outlet. Do not attempt to modify the output connector or operate the supply with a damaged cable.
