Quark-elec QK-A013 12V to 5V Low Interference Converter 0.5Amp

The QK-A013 is a 12.0V to 5.0V low noise power converter which converts 12.0V (or 24.0V) battery power into a stable 5.0V USB power source.
Originally designed for marine use (where radio interference needs to be kept to a minimum). It’s specifically designed to create very low amounts of noise and interference. This makes it ideal for all applications and locations.
The QK-A013 can easily be connected to different types of batteries. It is most frequently used on boats, cars, and caravans when a stable 5.0V power source is needed for sensitive equipment requiring a USB connection (marine electronic devices, mobile phones, etc.)

If you are looking for a standard 12-24V to 5V DC power supply for the digital circuit or just want to charge the battery of your devices, please go with A013-1.5A, which provides a higher current while keep the standard power ripple level.

Minimal Noise Interference

In addition, it is ideal if you have electronic equipment like radio, TV, AIS Receiver, etc. nearby.

So that you will be able to convert power without the interference common to other power converters.

• High-performance: 12V to 5.0V converter
• Low RMS noise: 0.8μVRMS (10Hz to 100kHz)
• High PSRR: 79dB (at 1MHz)
• Accurate and stable output current
• Maximum output current: 500mA
• Ideal for noise-sensitive RF applications
• LEDs indicate 12V battery capacity(check voltage level)

The 12V Battery Indicator

The 12V battery indicate function is ideal if you want to monitor the battery level of your 12V Battery.

Please note: The 12V battery indicator will only work when connected to a 12V battery. The converter will also work if you want to convert 24V to 5V, please note the battery indicator will not work when connected to a 24V battery.

When to use

The QK-A013 can easily be connected to different types of batteries – whether on your boat, in a car, caravan and have an electric device that needs a 5 volt supply.

How to use

Simply connect the power source cable to your 12V.

On the other side of the QK-A013, simply plug in your USB device.

The battery indicator will help you keep track of the battery life. This is very important with 12-volt batteries.

Designed for low interference

The QK-A013 has been specifically designed for low noise interference, as opposed to other power converters, which might lead to interference on your radio or equipment.

Designed as a stable power source

In addition, the QK-A013 has

• a low 0.8μ Voltage Root Mean Square Value (VRMS)
• a high 1 Mhz Power Supply Rejection Ratio (PSRR)

This combination results in very accurate and stable output current.

Ideal as a very stable power source – for sensitive equipment powered by a 5V USB connection (such as marine electronic devices, mobile phones, etc.)

What’s included?

• 1 x QK-A013

(USB cable not included)
