Description:

30W high power wide voltage automatic buck module performance than LM259, LM2577
Output voltage can be higher or lower than the input voltage is more flexible
Product Performance Description:
Weight: 12g
Appearance Size: 48 * 26 * 13mm (L * W * H)
Input voltage range: 5.0-25V
Output voltage range: 0.5V-25V (Output voltage can be higher than can be lower than the input voltage, but follow the principle of conservation of energy)
Continuous output current: 3A (max) long working hours within please ensure 2A
Continuous Input Current: 3A (max) long working hours within please ensure 2A
Input / Output Power: 30W (max)
Input / Output Current: rated conditions of calculation of the input / output current based on power conservation (Uin * Iin * efficiency = Uout * Iout)

Instructions and precautions:
IN +: Enter positive IN-: Input Negative OUT: Output + OUT-: output negative
Enabling switch: Disconnect shorting cap module stop output.
• No input reverse polarity protection, reverse will burn, please note polarity when in use.
• Output short circuit module will automatically stop output, re-plug the enable switch shorting cap can be restored.
• Module at no load and off load easily start momentarily output voltage exceeds a preset voltage, it is not suitable for voltage sensitive equipment.
Note that the input is negative, then the wrong direct damage
