TRANSISTOR WELDING POWER SUPPLIES MDA-10000A/MDB-5000A Transistor-controlled welding power supply Short-time, Large-current Welding by Multiple Connection of Power Supplies [ Current rise of transistor-controlled welding power supply is faster than others. ] Weld current Capacitor discharge DC inverter MDB-5000A (Left: Slave unit / Right: Master unit) Welding time Features ■　Multiple connection of power supplies realizes high power welding at short time. 　　 MDA-10000A: Maximum twelve units connectable (One master and eleven slave units). Design your own system to add power supplies as much as you need to obtain enough power. ■　One master unit controls all connected units. 　　 It does not necessary to set the weld schedule at each unit anymore. A master unit is an only unit to need to be set and controls all slave units. ■　All units' current feedback. 　　 The current feedback feature controls to stabilize current collectively from all connected units. ■　Polarity switchable type: MDB-5000A 　　 Alternate current flow from plus and minus side reduces Peltier effect and shapes nuggets uniformly. Best suited for series welding applications. ■　 Three control types to choose from. 　　 Both MDA-10000A and MDB-5000A employ the following three types of control: Constant current In the intial phase of welding Constant voltage & control works and supports welding without weld Constant voltage splash. Then, Constant current control works to keep current constant and supports stable welding. Constant Voltage Stabilize voltage from the beginning of the welding The timing when Constant current control starts to process and suppress current. Reduce weld splash. work can be set up. Constant Current Apply constant current to a workpiece regardless of the resistance of it. Ensure stable welding. Optical sensor parts Crystal oscillators Projection welding of electronic parts
