Features USE AS POWER CONVERSION MODULE: The output is speed regulated and adjustable, which can be used as a power conversion module, not comparable to other single transistor speed regulation. ADJUST MULTIPLE MOTORS OR FANS AT THE SAME TIME: The control module can adjust the speed of multiple motors or fans at the same time. The total load is less than or equal to 4A. INSTANT OVERINTENSITY PROTECTION FUNCTION: The output has instant over-current protection function, stable and reliable to use. COMPATIBLE WITH 4-WIRE 2-WIRE INTERFACE: Compatible with 2 wire 4-wire interface with 4A DC brushless fan or DC brush motor speed regulation. COMPATIBLE WITH 12V, 24V: The fan speed controller card is compatible with fan speed regulation or motor 12V, 24V, 5V, very convenient. Specification: Item Type: Fan Speed Control Module Model No.: FC-DT00-P000 DC supply voltage range: DC5-30V Current: 5A Output power: according to the load (maximum output power of 20W) Select the power supply: the voltage depends on the charging voltage (reserve at least more than 20% of the power capacity) Output voltage regulation indication: the power output has an LED indicator Package list: 1 x Fan Speed Control Module Package List 1 x Fan Speed Control Module
