电流限制
电流等级
7100A单相可控硅的电流等级从16A，最大到250A，只有在250A可控硅才需要风扇冷却，电压范围最大到500V。
输入
7100A单相可控硅可接受的电压类型 (0-5V or 0-10V) or电流输入类型 (0-20mA or 4-20mA) 。
触发方式
The 7100A is available with a selection of firing modes to suit most applications.
It is suitable for controlling resistive loads with high or low temperature coefficient, short wave infrared (SWIR) or inductive loads.
控制模式
7100A units use one of the following control parameters
RMS load voltage squared V2
RMS load current squared I2
Load power P (up to 100 amps)
Open loop OL
限制与报警
Optional current limit which can work in all firing modes prevents excessive currents from flowing in the load circuit. Optional alarms can warn of thyristor short circuit or load open circuit (GRF alarm). Additionally partial load failure with automatic set up can detect the loss of one out of six parallel loads (DLF alarm). Over temperature shutdown is provided with 250A fan cooled units with optional alarm.
快熔
High speed fuses are recommended for most applications except SWIR. The fuses are external for units up to and including 100 amps and internal above 100 amps.
Fuses are available either with or without microswitch indication.
国际认证
