Chapter I. Safety Precautions
Read this user manual before using GoHz frequency converters.
Keep this user manual near the frequency converter for reading at any time.
Handle with care when transporting the frequency converter to avoid collision.
Do not put the frequency converter on uneven or inclined place.
Do not block the venting holes or slits to keep the frequency converter well-cooling effect, the back of the
frequency converter should keep 10 cm (4 inches) away from the wall.
Double check the frequency converter and power supply specifications are matching and well-wired before
power connection to avoid any careless damaged.
Frequency converters have different installations according to different capacities and voltage levels,
choose an appropriate configuration and wire diameter.
Do not overload the frequency converter and wire to prevent the electric shock or cause fires.
Please follow the implementation of electrician laws and regulations.
In case of abnormal phenomenon happens, follow this user manual in troubleshooting or contact the
manufacturer.
Please keep frequency converter clean and do not put heavy objects on top of it.
Prevent any liquids and sundries into the frequency converter, in order to avoid poor contact or short circuit
to cause electric shock or fire.
Better to unplug the power cord in storm, lightning or thunder days.
Avoid placing in direct sunlight, raining or humid place.
Keep it away from the source of ignition and heat to prevent overheat.
Shutdown the power cord during moving or maintaining the frequency converter.

Chapter II. Working Principle
GoHz multi-function programmable frequency converter is a standard AC power supply electronic device, it can
simulate international standard power supplies, convert fixed AC voltage and frequency power into stable pure
sine wave power by internal AC to DC, DC to AC current rectifying, with high activation current, and displays a
number of parameters (Such as: voltage, frequency, current, apparent power, power factor etc.).
GoHz programmable frequency converters adopt advanced PWM (Pulse Width Modulation) technology with
compact size, light weight and high efficiency features. Digital Signal Processor technology provides high
precision measurements function of voltage, frequency, current, apparent power and power factor etc. The use of
high power IGBT module design to reduce circuit complexity, enhance frequency converter stability and reduce
power consumption. And the isolation transformers completely isolate the mains and the loads, in order to
improve the loads stability and a variety of testing performance, to ensure the accuracy of test values for the
loads.
GoHz programmable frequency converter provides voltage (0 - 300V) and frequency (standard 40Hz - 120Hz,
120Hz to 499.9Hz is optional), suitable for general commercial electrical and electronic machines.
