Description: 1. The use of synchronous rectifier converter design, high efficiency, high current work doesn't require additional heat sink, the output is smooth DC (no pulse), direct drive output design. 2. Can support all 12V 5A within the fan, including brush DC motors, pumps, light bulbs, etc. Can't exceed the maximum current conditions can work more than one fan in parallel, a soft-start power. 3. Can be adjusted by rotating the board any manual speed control resistor. 4. With four-zone automatic temperature control variable speed function, plug in the temperature control probe automatically after the entry into force, temperature control will manually adjust the speed to the lowest speed, the highest speed is 12V through. The linear speed of the middle speed change. 5. With the work monitoring function of a channel, can support a way with a speed wire (such as three-wire fan) stop monitoring alarm, when the speed is less than 450 rpm sound and light alarm (need to be equipped with buzzer). Specifications: Working voltage: DC 12V Circuit load capacity: maximum current per output 5A, the bus current up 9A Output range: the first channel: 20%-100% or 40%-100% (TFL = ON); the second channel and the third channel: 10%-100%; (Note: above range only for PWM range, the actual control effect will vary depending on the fan) Temperature probe parameters: 50K B=3950 Thermostat temperature zone error: error depending on the temperature probe, generally 3%-5% Stall alarm minimum speed: 700-800 rpm Circuit board size: 50 x 49 x 15mm Center distance of locating hole: 44 x 43mm, diameter: 3.2mm Setting switch description: TFL(No.1): the lowest temperature channel PWM setting, when ON state FAN1 PWM minimum is 40%, when OFF the minimum PWM of FAN1 is 20%,.
