eFuel 50A DC Power Supply

eFuel 50A DC Power Supply
Price: $359.00

With 1200W outputs, adjustable output voltage from 15-30V and active PFC, it is the most advanced power supply you will find anywhere.

1200W of output is ideal for a variety of high powered chargers, and three outputs allow you to simultaneously operate multiple chargers or other devices.

An input voltage range of 100-240V makes it ready for worldwide compatibility with no setting required, and the DC output voltage is flexible: simply turn the dial to adjust the voltage to suit your setup-digital readouts give you an instant look at your output voltage and current.

Active power factor correction and a compact frame make this a great power supply to take to the field and use with a generator.

DC Output
One main DC power output, up to 50 amperes, three outputs (up to 10 amperes each) with ON/OFF switch. 1200W output gives you all the power you need to run your high-powered application, or use multiple chargers simultaneously with three sets of integrated banana plug outputs!

Adjustable Output
Voltage 15-30V

LCD Display
The output voltage and current are displayed on the digital readouts on the front, allowing you to identify the voltage and current at a glance. 

AC Input 100-240V
Worldwide operation: need not any alternative switcher, worldwide safe operation. 

Two USB Ports
It is 5 volts, 2100mA total for iPad, mobile phone, digital cameras and etc.

Smart Cooling Fan
It turns on at 50 °C upon the temperature automatically.

Safety Features
Over current, over voltage, over load and over temperature protection. Short-circuit protection on output, safer and more reliable. 

Active PFC
Active PFC: smaller AC input current less interference, and Conform to CE Regulations. And it can also improve the energy consumption from mainpower grid evidently. 

Power Factor Correction
(PFC)allows power distribution to operate at its maximum efficiency. There are two types of PFC, Active PFC and Passive PFC
The preferable type of PFC is Active Power Factor Correction (Active PFC) since it provides more efficient power frequency. because active PFC uses a circuit to correct power factor, active PFC is able to generate a theoretical power factor of over 95%. Active Power Factor Correction also markedly diminishes total harmonics, automatically corrects for AC input voltage, and is capable of a full range of input voltage.
