STQ(M)L In Rated Voltage Controlled Mode For lifting magnet
STQL Three Phase Silicon Controlled Commutation mode
This equipment series will reduced voltage of the three-phase alternating current power supply through transformer and produce 220 DC by three-phase bridge-type silicon controlled commutation unit. The unit is consist of auto air break switch, transformer, 3 phase bridge-type rectifier assembly and DC contacts. The circuit has short circuit and over-voltage safety protections. The unit features compact, light weight, less occupation, steadily operation and convenient in service. The rectiformer will be equipped outside when the handling capacity of the controlled electromagnet is larger than 19kw.
STML Single Phase Silicon Controlled Commutation mode When the handling capacity of the controlled lifting electromagnet is much less than 4kw, the single phase bridge-type rectifier will be adopted.
