Specifications: Voltage: DC 5V~36V. Trigger Signal Source: High voltage level trigger (3.0V~24V), signal ground and system ground are not on common ground to improve the system's anti-jamming capability (you can also connect them on common ground). Output Capacity: DC 5V~36V, at room temperature, continuous current is 15A, power 400W. With enhanced heat dissipation, the current can be up to 30A. Quiescent Current: 20mA Operating Current: 50mA Working Temperature: -40℃~85℃ Clocking (Time Delay) Range: 0.1seconds to 999minutes Size: 60*34*12mm / 2.36*1.33*0.47" Note: 1. The module is an active output, the output voltage equal to the input voltage. 2.'DC + 'and' load + ' are internally shorted(connected), but' DC- 'and' load - ' cannot be shorted, otherwise the load cannot be controlled on and off, which is equivalent to load being powered on always. Package Includes: 1 x Timer Switch Module
