No official manufacturer datasheet exists online for the 'GYD-9E' assembly, as it is a generic board. However, the details can be derived from datasheets for the DF6113 controller IC.
With RθJA = 45°C/W, temperature rise = 171°C → . Solution: Add a heatsink or forced airflow, or reduce input voltage to 12V. This example shows the importance of checking thermal limits in the datasheet. gyd-9e datasheet

A: For resistive loads at ≤70% rated current, MTBF exceeds 5 million switching cycles. For inductive loads with snubber, expect 1–2 million cycles. For DC loads (inductive), lifespan drops significantly due to arcing on turn-off.
A: No. It has an internal LED and trigger circuit. Simply apply DC voltage to the input pins. For inductive loads with snubber, expect 1–2 million
Yes. The DF6113 IC is reported to work with a PWM signal for dimming. This would involve applying a pulse-width modulated signal to the DIM pin.
