◆ Multifunctional: Multiple voltage and frequency quick groups, power down memory function, display of fault code information; Equipped with black box function.

◆ Adjustment mode

(1) Three phase unified regulation mode: standard three-phase power supply with synchronous frequency and voltage regulation for three-phase output;

(2) Three phase modulation mode: The three-phase output is an independent circuit, independent frequency and voltage regulation, independent high and low gear switching, independent start and stop of each phase, without interfering with each other. The power capacity of each phase is one-third of the total power capacity;

(3) Three phase parallel mode: The three-phase output is connected in parallel to form a single-phase output, with the output capacity equal to the total capacity of the power supply;

(4) The three modes of power output share a common neutral line.

◆ Programming Steps Function

The TK99 series programmable variable frequency power supply has a step function. Through the built-in step function of the machine, it can simulate various power step conditions based on the step parameters set by the user, such as step voltage, step frequency, and step duration. The product has excellent response speed, so the step changes in voltage or frequency can be completed within a single cycle, making it suitable for simulating power grid disturbances or power switch testing projects.

◆ Programming's slow rise and slow fall function

TK99 series programmable variable frequency power supply hasSlow rise/slow fallFunction, based on user settingsSlow rise/fall parameters, such as unitsSlow rise/fall time, unitSlowly increasing/decreasing voltage and unitSlowly increase/decrease frequency to simulate various power sourcesSlow rise or slow fall condition. The power supply can be transmitted throughThe slow rise function adjusts the climbing speed of voltage or frequency, effectively reducing the surge current generated by motors or compressors during startup.
