1U Half-Rack Mini Size

The conventional AC power supplies are much bigger and heavier, difficult to move. The size of IT-M7700 is only ½ 1U, but its max. power is up to 600VA. Its weight is 4.5kg only. With such high-power density design, the space is better utilized. So it can be portable, convenient for bench testing and good for system building.

Arbitrary Waveforms Output

Users can self define arbitrary waveforms through IT-M7700 software and download to power supply so as to simulate or duplicate the real waveforms.

Harmonic Analysis Function

IT-M7700 series support 40th voltage/current harmonic measurements with the frequency ranging from 45Hz to 50Hz. The analysis results can be easily displayed in list or column formats.

List Mode

IT-M7700 LIST mode supports program complex waveform editing. The users can edite 5 list files, each file can be edited up to 50 steps. Each step settable parameters include: basic waveform (incl. THD and user defined waveform), AC/DC amplitude, slew rate, frequency, dwell time, start/stop phase angle, times of repetition etc. This function with complex waveforms can help users to simulate grid disturbance, periodic power off and so on.

* Available with ITECH PC software

Multiple Output Modes: AC, DC, AC+DC

The output modes of IT-M7700 series include AC, DC, AC+DC. It can not only provide pure AC or DC output but also AC+DC output mode which can expand application fields and test DC offset element.

Leading and Trailing Edge Dimming

The IT-M7700 series supports front and rear phase angle dimming or speed control tests. The user can adjust the active power by setting the phase angle and performing the leading or trailing edge waveform concealment to achieve the purpose of adjusting the light intensity of the lamp. It is used to verify whether there is a quality hazard when the end user uses the dimming or speed controller.

Trailing edge

Adjustable Waveform Start/Stop Phase Angle

IT-M7700 series supports the initial phase and stop phase of the output waveform settable to meet different test requirements. The initial phase and stop phase are set in the range of 0-360°. By adjusting the phase angle, the user can test the rush current of the product at different positions which is widely applied to various switch current impulse tests and various rectifiers test.

Adjustable phase angle

Application: LED Driver, Household Appliances and Other Products Input Surge Current and Power Supply Disturbance Performance Verification

Built-In AC Power Meter

IT-M7700 provides built-in AC power meter which can accurately measure and display 12 parameters on the screen, including rms voltage, rms current , output frequency, active power, power factor, etc. No need for additional power meter. So it can not only reduce test cost but also get rid of the complex connection operation.

Comprehensive Protection

IT-M7700 series provides comprehensive protection , including OVP rms, OVP peak, UVP rms, OCP rms, OCP peak, OCP delay, OPP, OTP and smart fan dysfunctional protection.

Application: LED Driver, Household Appliances and Other Products Input Surge Current and Power Supply Disturbance Performance Verification

When testing a capacitive load with an AC power supply, the voltage will suddenly drop due to high current impulse, which will lead to failure load. At the same time, excessive surge current will easily cause damage to the AC power supply. Therefore, comprehensive protection is essential for the AC power supply. The picture on the right shows the voltage and current curves of the incandescent bulb tested by the IT-M7722.
