Soft start function: 5-second soft start when powered on, soft start when thermostat overtemperature occurs, soft start when half cycle dropout detection occurs, 1-second soft switching when set value changes, protecting load and devices 🔶 1-124 🔶 1-125 🔶 1-126.

(2) Single cycle variable time base (Type S)

Working logic: At 50% power, "1 cycle on, 1 cycle off"; At 25% power, "conduct for 1 cycle and close for 3 cycles"; Continuous conduction for no more than 1 cycle when power is less than 50%, and continuous shutdown for no more than 1 cycle when power is greater than 50% 🔶 1-110.

Accuracy and adaptability: The output power is proportional to the command signal at 25 ° C, with an accuracy of ± 5%; Temperature stability<0.25%/° C; supports linear voltage, 4-20mA or potentiometer input 🔶 1-120.
