1-2, Master Control Broad: Master Control Broad uses imported integrated circuit. Rectifier triggers do not need any adjustment, it has phase sequence to adaptive electric circuit with high reliability. Inverter adapts sweeping-frequency and zero pressure start-up; it has the function of heavy load starting. Frequency tracking circuit using the average sampling programs to improve anti-jamming capability of the inverter. Inverter circuit also added inverter angle regulating circuit, which can automatically adjust load impedance matching.
1-3, Protection and Control: Master Control Broad internal function includes: Rectifier phase shifting trigger, Phase self-adaption, Inverter trigger, Reverse lead angle lock, Inverter repeat start, Over-current protection, Over-voltage projection, Open-phase protection, Hydraulic under-voltage protection, Control panel under-voltage protection etc.
