WTC has more than 20 different sizes and configurations of inverters to suit your needs. Each of them are identified by an alpha-numeric naming convention.
G6: Signifies the 6th generation of inverters from WTC's development cycle
E: First letter after the dash means the base rating current
First letter after the dash means the base rating current
A: 100 amperes at 10% duty cycle
B: 400 amperes at 10% duty cycle
C: 600 amperes at 10% duty cycle
D: 1000 or 1200 amperes at 10% duty cycle
E: 1800 amperes at at 10% duty cycle
S: 900 amperes at 3% to 5% duty cycle
Z: 900 amperes at 2% duty cycle - Projection Welding Steel applications
F: 2400 amperes at 10% duty cycle
G: 4800 amperes at 10% duty cycle
H: 7200 amperes at 10% duty cycle
W: Cooling method for the inverter
There are two methods for cooling
A: Inverter is cooled by air fins
W: Inverter is cooled by water circulation
6: Peak voltage rating for the power bus of the inverter
There are two ranges
4: Inverter IGBT peak voltage rating = 530 volts; optimal for voltage mains of 500V and lower
6: Inverter IGBT peak voltage rating = 630 volts; optimal for voltage mains of 600V and lower
