Programmable Frequency Conversion AC Power Supply

TFP-A series is programmable AC Power Supply can provide power grid electricity from all over the world and according to rated standard rules to simulate the normal and abnormal condition of power grid. Suitable for laboratory, certification authority, university, research institutes, meet the product requirements of design, development and certification test. The products are widely used in new energy industry such as energy storage inverter, photovoltaic inverter, wind energy converter, it also can be used in household appliance, motor test in laboratory. The product adopts advanced digital high frequency inverter control technology and high speed digital controller, achieve the SIN output wave of high accurate, fast dynamic response speed, high load adaptability, high stability, wide output range. With many output modes and strong programmable function, It is power grid simulated equipment with high effectiveness and good performance.

  Strong output management function.
 3 phase standard mode: standard 3 phase voltage output.
 3 phase balance mode: each phase voltage can be set in separately
phase angle can be adjusted between 0.0~399.9
 Single phase separated mode: each phase voltage and frequency both can set separately, Equivalent to 3 units of single phase power supply.
  Single phase parallel mode, 3 phase connection in parallel to achieve single phase output with large power capacity.
 With list, step and various sequence test function, comply with the requirements of IEC61000-4-11, IEC61000-4-34.
 Fast dynamic response speed, time of abrupt voltage change in 20ms.

  Output waveform can be adjusted in real time, cutput voltage and output frequency setting can be adjusted in real time by numeric key,
+/-button or Knob, It also change the output waveform mode and update output immediately. Observe the performance of equipment under test at certain time of abnormal power grid situation.

  With the Auto-lock function, lock the key automatically understand the condition of unmanned operation, avoid the wrong touching to cause the man-made accident or danger.

 8 inch colored LCD display, with the input key of number key, function key, knob; exquisite appearance, easy operation.
 Build in multifunction, high speed and precision, measure accurately
Vrms, Irms, peek current, voltage peek factor, actual power, apparent
power, power factor and so on.
  With the Al-Monitor function, monitor the internal voltage, current, temperature at real time; In case of the abnormality, trigger the alarm immediately, and prompt the operator to deal with it in time.
  With the Black-Box function, while the accident occur without people monitor, record automatically internal and ext-operating  parameters and save into internal dedicated chip, all the data can be checked at any time, learn more the details of accident to do maintenance easily.
  The main components adopt the international famous brand with good quality and stable usage.
 The key technical of equipment adopts multi-design margin, voltage stress, current stress, calorific value are strictly demonstrated in technique, and seriously verified. High reliability, long life time.
  Complete communication ports, standard RS232, optional RS485, GPIB, LAN, Analog control.

 Typical Recommendation :

  Three-phase decoupling design, with complete power grid abnormal simulation function: power grid distortion, power grid fluctuation, three phase unbalance, 2-40 times harmonics can be superimposed in harmonic mode.

 Multiple output modes, "one machine multi-purpose" 

TFP-A series adopts three-phase decoupling control, combined with digital control algorithm, to achieve a variety of mode output: three-phase standard mode, three-phase unbalanced mode, discrete single-phase mode, parallel single-phase mode, one power supply is equivalent to a variety of traditional power supply functions, so that "one machine with multiple uses".

  Adopt the accurate anti-impulse technology, withstand load high current surge, three rated current can be endured 2s, especially suitable for motor and other surge equipment. Due to the strong overload capability, capacity can be reduced appropriately and saved the cost when choose the anti-impulsed power supply model such as 90kva power supply can start 30kva motor.

 With soft start function and soft start time can be set, suitable for motor and other high start equipment, accord the situation to set
soft start time with and decrease surge current.
