Control method
Analog input: Phase control or optimum cycle control
Voltage ON/OFF input: ON/OFF control
Maximum load capacity
• Phase control: Linear (resistive) load, transformer primary-side control
(Magnetic flux density: 1.25 T max.)
• Optimum cycle control: Linear (resistive) load (Transformer primary-side
control is not supported.)
