Ground Power Unit

Why 400Hz?As we know,Website:http://www.acsoon-power.com,the aircraft is using 400 Hz power supply and it is because the higher hertz of the power supply system, the lesser of copper and steel materials of the generator and transformer being used, which lead to light weight and low cost. The disadvantages are the electrical equipment and wiring inductance increase, capacitances decrease, losses increase, reducing the power transmission efficiency. Conversely, lower hertz will increase the use of materials, which lead to higher weight and costs. So, 50 Hz, 60 Hz is an appropriate value for mains power supply, 400 Hz for aircraft, military, vessels, navy ships etc.Acsoon® AF400W series is one of the most popular static frequency converters. AF400W is designed to change the power at 50Hz or 60Hz to aircraft quality power at 400Hz.It integrates with IGBT((Insulated Gate Bipolar Transistor) made by Mitsubishi, Siemens, and Infineon, and combines microprocessor made by ACSOON to accomplish quicker response and higher reliability.So Acsoon ® AF400W as a power source to develop aircraft quality 400hz Power. It has strong adaptability, high stability and stable output waveform and  the volume is relatively small.There are mostly used in aircraft production manufacturing,military/civil hangar, maintenance plant, aerospace equipment, military airport tarmac and wells, .Main Features☆ A variety of power requirements with single, dual or triple outputs☆ Galvanically isolated, low harmonic distortion☆ Isolated output transformer, suit for any unbalance loads☆ Better overload capacity☆ Thoroughly proven advanced SPWM and IGBT technology☆ Pure sine wave output☆ Eco-friendly, high efficiency, low noiseThe Acsoon® AF400W series ground power unit model is shown below:Acsoon® AF400W series SFC are available with following capacities:Triple phase output: 10KVA ~ 450KVASpecification● Capacity☆ 10KVA to 450KVA●  Input☆ Voltage:1 phase 120V+/-15%, 1 phase 220V+/-15% or 3 x127V/220V+/-15%,3 x220V/380V+/-15% Or as per your specific requirement (select one individual voltage)☆ Frequency: 40-70Hz☆ Power Factor:     ≥0.8 （Standard type）    ≥0.9（12 pulse type, optional item）☆ nrush current: None, soft start●  Output☆ Voltage:3x115/200V(L-N/L-L), 3x120/208V(L-N/L-L)    Or select one individual voltage☆ Frequency: 400Hz☆ Voltage regulation: +/-1%☆ Frequency regulation: +/-0.01%☆ Crest: 1.414+/-0.05☆ Distortion: THD<3% @ linear load☆ Phase angle:    120°+/-1° (No Load / Balance Load）    120°+/-2° (33% unbalance Load）    120°+/-3° (100% unbalance Load）● Overload    125% for 5 min; 150% for 1 min;    200% for 30 sec; 300% for 5 sec;400% for 1 sec ● Protection☆ Over/under voltage,☆ Over current, Over load,☆ Over temperature,☆ Phase loss , Short circuit,☆ Self diagnose and alarm☆ Voltage difference between each phase＜2V● LCD display:Voltage, Current, Frequency, Power/PF● Available options☆ 28 VDC, 50-4500 A output☆ Additional output contactor☆  Adjustable output voltage/frequency☆  Interface: RS232/485☆ Remote control box☆ Terminal extension for 2 PCS of 7 core cable☆ 28VDC interlock ● Working condition☆  Ambient temperature:-40 to 50℃☆ Humidity:0~95% non condensing☆ Noise:< 65dB within 1 meter☆  IP20 / IP32 / IP55☆ Altitude<1800m● Reliability☆  Mean Time Between Failure (MTBF) 50,000H☆ Mean Time To Restoration (MTTR)< 30 min● Standards☆ DFS400☆ MH/T6018☆  ISO 6858☆  MIL-STD-704☆ EN62040-1-1☆ GJB572 ☆ EN61000Typical Models and InformationModelCapacityPhaseMax. WeightDimensions for trailer type                     (net size in mm)    without trailerType*InOutLWHAF400W-33001010KVA33--1000600500V/TAF400W-33002020KVA33--1000600500V/TAF400W-33003030KVA33---1000900600V/TAF400W-33004545KVA33350KG1000900600V/TAF400W-33006060KVA33480KG1000900600V/TAF400W-33009090KVA33550KG16001100700V/T/BAF400W-330120120KVA33 850KG16001100700V/T/BAF400W-330180180KVA331150KG16001100700V/T/BV for vertical type with fixed mountedT for Trailer mounted,B for Bridge mounted.For more models with different capacity, please contact us.
