Product Name: Multi (3-5) Outputs Spot Welding Power Supply Mddl-1000s Model NO.: MDDL-AL/3AT & 5AT Trademark: minder-hightech Transport Package: Plywood Specification: 30kg Origin: Guangzhou HS Code: 8515219000 Product Description Multi(3-5) Outputs Spot Welding Power Supply MDDL-1000SCharacter:1,IGBT inverter with 4kHz frequency.2,Three welding pulses with upslope and downslope.3,Constant-current/constant-voltage/constant power/fixed pulse width control mode.4,Upper and lower monitor of the current or the voltage etc.5,Easily operating,.6,Full I/O interface. The power supply can be easily used on aautomatic machine.7,Over heat false/wrong input voltage false/over control false.Principle:As the main circuit diagram below, the inverter welding power supply working principle is :(220V 50Hz AC)-----(310V 50Hz DC)-----(310V 4kHz AC)-----(5-18V 4kHz DC). That is why the frequency being changed, because of the high frequency, the welder become more precision.1, for 50Hz, we can only set 20ms welding time as aunit. but for 4kHz, we can set 0.25ms welding time as aunit, 80 times inproved.2,when we do closed-loop constant control, the feedback speed is different, 20ms once by 0.25ms once, it is very much different.AS the waveform of pulse DC current is flat, not like AC curve and around "zero"We have compared that the DC power supply can sace more than 50% power than AC ones.Advantages of inverter seam welding power supply and the current waveform of capacitor type/AC type/inverter type/crystal typea,Inverter type of seam sealing power supply can saving 50% power than others.b,Inverter type of seam sealing power supply can improve 3% stability than others.means less defective products.c,Inverter type of seam sealing power supply can be much faster than others.Specification:Model/NoMDDLH-1000MDDLH-2000MDDLH-3000MDDL-4000MDDL-6000C/TMDDL-10000C/TMDDL-20000C/TMDDL-40000C/TInput Voltage(V)220V220V220V3*380V3*380V3*380V3*380V3*380VRated Power(kVA)46101216254065Max current(DCA)10002000300040006000100002000040000Max time setting(ms)12501250125012505000500050005000Rated duty cycle(%)2020201010101010Frequency(kHz)44441111Welding step33333333Upslope downslopeYesYesYseYesYesYesYesYesSchedule memory2020202020202020Dimension(mm)435*185*320435*185*320435*185*320460*400*300460*222*345385*200*300510*270*400440*240*350Weight(Kg)1820.5223323.526354626.5304051inverter spot welding Power supply testing:Multi-output power supplies:Other Models of power supply:--------------------------------------------------------------------------------------------------------------------------------------guangzhou minder-hightech co.,ltdcontact:shunyu.hu cellphone0086-15813334038
