BACKGROUND

It took us 2 years to come out with a successor of our popular 1.5A Car Power Adapter
We ask and we listen hard.
They want more power (amps) from the adapter and car battery.
But they worry about the over discharge of car battery.
They want to see the selected output voltage.
They want to know the car battery state of charge (voltage).
They want to see how much current the plugged in device is drawing.
They want at least one USB charging port just like the one in PC.
They want more protections for their expensive portables.
They want ……
So, we come out this new Car Power Adapter that meets all wants.

With Micro-processor control, this digital car power adapter has the following:

Car Battery Protector with Alarm

Prevents car battery failure due to extended use of current draining devices, like DVD player , it cuts out the output at low battery level and cuts in when voltage returns to normal.

Digital Selection of 7 Output Voltages

No more guessing, no more in-between, your selected voltage is shown and selected digitally.

Display of Battery Voltage and Load Current

Digitally read out of your battery voltage ,you know if your car battery is running low or even if your alternator is working properly.

A bar chart shows current drain state of the plug-in devices.

Dual Outputs

One 3 Amp regulated output to power your device smoothly at the selected voltage.

One USB port regulated to USB standard and works with all USB link cable for portables like PDA , I-POD , PSP Player, Cell Phones , Mp3 players etc.

Additional Protections

Output Over Voltage protection to protect your delicate, voltage sensitive PMP Devices from power surges due to accelerating and braking hard.

Universal Input

Works with all vehicles , truck, lorry , cars , boats 12 volt or 24 volt DC source

5 LCD back light colour for user to select at any time.

General Description

SDC 5203 is a DC-DC converter which is designed for car and truck application making use of the DC power source from the cigarette socket. The converter is suitable for both 12V / 24V battery system. This digital car power adapter has a Micro-processor Control to protect your car battery from over-discharge .The 3A dc output is digitally selected and displayed .The LCD shows battery voltage , selected output voltage , and the load current. It has one USB output and one main DC output with 7 selectable voltages for 12V and 8 for 24V battery system. The rated current of the main DC output is 3A and USB output is 700mA.
