Fine workmanship, good performance and long service life. Delay fan special module, off delay disconnect module specifically for cooling fans, exhaust fans, etc. delay. Easy to understand function, turn on the output when there is a signal, turn off the output when the signal disappears. 4-speed adjustable, easy to operate, zero standby power consumption, power saving and safety. Product parameters: Name: Power-off delay disconnect module Model: QF-RD21F Voltage: AC 100V-220V Power consumption: <1.0W standby zero power consumption Time range: (4 gears, selected by switch) First gear: range 0.2 seconds-30 seconds, precision: 0.1 seconds Second gear: range 0.2 seconds -300 seconds (5 minutes), precision: 0.3 seconds Third gear: range 0.2 seconds-30 minutes, accuracy: 1.8 seconds Fourth gear: range 0.2 seconds-300 minutes (5 hours), precision: 18 seconds Output: output voltage is the same as input voltage, maximum power supply capacity is 10A Life: 100,000 times action Function: turn on the output when there is a signal, turn off the output when the signal disappears Size: length 88mm * width 36mm * height 22mm Screw hole: center distance 83mm * 31mm, hole diameter 3.2mm Note: The start button needs to be able to withstand the load current for a short time (about 0.3 seconds), which means that if you control a fan with 5A current, the start button should be able to withstand 5A and above current for a short time. Wiring column description: L: Fire wire access L2: switch output side fire wire, taken from the heating body fire wire N: zero line (public) FAN: fan output, fire wire Operating instructions: Setting of time range. When the selector switch is placed in the 30 position, it means 0-30 adjustable When the selector switch is placed in the 300 position, it means 0-300 adjustable Adjustment of time value: Adjustable resistor rotates counterclockwise in the - direction to reduce the time, and clockwise in the + direction to increase the time Setting of time unit: When the selector switch is in the Sec position, the unit is: seconds When the selector switch is in the Min position, the unit is: minutes Example. 50 minutes delay time is required: 1. Range set to 300 position 2. Time unit placed in the Min position 3. Adjustable resistor adjustment to the 50 position, adjust the full for 300, so adjust to 1/5 that is 50. Note: The potentiometer adjustment can also be adjusted quickly with a multimeter voltage file. For example, the range 30, need to be adjusted to 12, then the voltage can be adjusted to 2. t=Ut/5*30=2.0V / 5.0V * 30 =12 Ut is the voltage measured by the multimeter, 30 is the range selected by the selector switch, you can also choose to 300 Application Notes: 1. Delay a period of time after the heating equipment is turned off before turning off the fan. 2. Exhaust fan in the switch off after the delay off, not necessarily need heating device Product list: 1* Relay module Payment Method Shipping Policy Feedback Payment Method Payment must be received in 5 business days of auction closing.
