New 30V 10A LED Display Adjustable Switching Regulator DC Power Supply

New 30V 10A LED Display Adjustable Switching Regulator DC Power Supply


    The power supply uses advanced technology PWM + linear regulator, voltage, current can be continuously adjustable from 0 - Rating obtain
Ultra-low ripple. High-precision reference voltage source, rational circuit design, the ability to provide highly accurate output. High-power MOS devices
Application, to ensure adequate power supply, improve the long-term stability of the power at full load work. Perfect protection function, in order to protect the load
And the power supply are not damaged. Simple operation, and a plurality of power supply can be directly connected in series, parallel, expanded power
Range of applications.
1. High-precision LED digital display, intuitive and clear.
2.8 cm smart fan, excellent heat dissipation, effectively extend fan life and reduce noise.
3. The use of advanced technology to effectively reduce the weight of the power and convenience of mobile power.
4. A variety of protection, current limiting protection (OCP), over temperature protection (OTP), Over Power Protection (OPP).
5. plastic panels, more beautiful, voltage, current, coarse and fine adjustment knob to set the settings to be more precise.
