input/output

5 loops Analog Input and 4 loops switching value both could be program.

4 loops Analog Input and 3 loops switching value both could be program.

Protection

overcurrent protection

output current≥twice time of the rate protection.

failure frequency

frequency out off the range start to protect (45-65hz)

SCR overheating protection

SCR temperature >75°C

phase break protection

input power phase break on the major loop

load disconnection protection

load disconnection or parts disconnection

accuracy of adjustment

voltage and power control precede 1%
