Inverters & Converters

S300 has two series: A for asynchronous motor and E for synchronous motor. For example S300A-2-4T 5.5k suits for 5.5kw asynchronous motor and S300E-2- 4T 5.5K suits for 5.5k synchronous motor. Variable frequency dives system are widely used in paper making, food and beverage, packing, construction material, textile, machine tools, water supply and ventilation, rubber and plastic extrusion, etc. Frequency drive, also called servo drive, ac drive or ac inverters, is used to adjust motor speed and torque. In smart control industry, variable frequency drives are used to save energy and increase working efficiency. Variable frequency dives system are widely used in paper making, food and beverage, packing, construction material(such as brick making, construction hoist), textile, machine tools, water supply and ventilation, rubber and plastic extrusion, etc. Advantages of Micctech VFD system are mainly in these sides: 1. Micctech VFD system Suit for most of Asynchoronaus and synchoronause drive and support kinds of control method. For example: Asynchoronous drive can choose No PG flux vector control, with PG flux vector control and V/F control; For synchoronous drive, it can choose No PG flux vector control, with PG flux vector control. 2. Compatible encoder: It support rotary transformer and ABZ incremental encoder. 3. Communication: Modbus, CANopen and Profibus-DP. 4. Steady and reliable: Micctech uses high-class electronic units, excellent design, conformal coating on PCBA and independent air flue, all them work together to ensure the  VFD system has longer life time. 5. High starting torque: In No PG flux vector control mode, when output frequency is 0.25Hz, VFD can reach 150% rated torque; In PG flux vector control mode, when output frequency is 0Hz, VFD can reach 180% rated torque. 6. High torque precision: In No PG flux vector control mode, torque control precision is less than 7.5%;  In PG flux vector control mode, torque control precision is less than 5%. 7. Compact structure: Book style structure saves room for whole electric cabnet. More VFD system can be installed in the same width cabinet.

Product Description 380V 4KW 5HP 10A MPPT solar pump inverter VFD for submersible pump ZK SG600 solar water pump Inverter VFD mainly features: MPPT efficiency more than 99%. Drives well all kind of AC pump including PMSM in solar water pumping system. MPPT automatically tracking the DC bus voltage, can be set manuel too Dry run protection and full water tank detect Motor maximum current protection Low input power protection Lowest stop frequency protection The PQ (power/flow) performance curve enables calculating the flow output from the pump Digital control for fully automatic operation, data storage and protective functions Intelligent power module (IPM) for the main circuit LED display, LCD is avaliable. Ambient temperature for using: -10 to +50˚C. How to select the solar panels? Need enough voltage and power, and the Voltage can not big than input range. Input voltage, power solar selection Pumps model Inverte models Vmp Voc Total Power of solar arrays 110VAC pump 1S (for 110V) 130VDC 156VDC ≧ (1.3 to 2.0) rated power of Pump It is also depend on the quality of solar panels. The higher the power input, performance will be better 220VAC pump 2S (for 220V) 310VDC 372VDC 380VAC pump 4T (for 380V) 540VDC 648VDC

Product Introduction In response to a high torque and speed control For fast start-stop, suddenly loading and unloading of the occasion Mutation load, the torque limiter function of mechanical protection Pearl wave restriction function Can effectively prevent an overcurrent warning or interference caused by a sudden load, thereby protecting the safety device. Tracking speed smooth start Rich fault protection and operation monitoring function Diverse control Excellent current control ability, to ensure that the rapid acceleration process does not trip operation, and the acceleration time is shorter Powerful overload suppression ability to ensure that the inverter will not stop due to overload faults at the maximum output; Solutions 1. Inverter automatically working When the input DC voltage lower than 230V, the inverter will turn to dormancy. It will automatically wake up and working once input DC voltage higher than 230V. 2. Dry-run function with three solutions 1) Dry-run function without sensor. 2) Analog sensor detect Water function.
