Product Details

Sure Electronics PS-SP12151 300W 12V DC/DC Boost Converter Voltage Step-Up Board with TL494 IC

This 300 watt boost converter steps up your vehicle's 12 VDC output (11 to 27 VDC max) up to 48 VDC for use with high power amplifier boards. Select 24, 30, 36, 40, or 48 VDC output via four DIP switches located on the board. Precision voltage adjustments are accomplished through the surface mount potentiometer built onto the board.

A Texas Instruments-designed TL494 pulse-width-modulation control IC provides stable, military-grade voltage output, regardless of voltage setting. Additionally, low-voltage and over-voltage input protection is built-in and a current sensing fan kicks-on when current output is greater than 3 amps. Further protection is provided by two 25A ATC automotive fuses.

This boost converter is different than many car audio electronics and amplifiers. With 12 VDC input power, the boost converter is in an on condition, and is boosting voltage to the preset output.

To turn boost converting off, 12 VDC needs to be applied to the EN input terminal. It is recommended that you wire EN to a SPST switch and then to 12 VDC in the event you need to turn boost converting off. The current consumed by this boost converter is 20 mA when not driving a load.

Note: The manual incorrectly states that the LEDs will illuminate green. The LEDs actually illuminate blue when the boost converter is operating correctly.

Features and Specifications:
• Input voltage: 11 to 27 VDC
• Output voltage: 24, 30, 36, 40, 48 VDC
• Quiescent current: 20 mA
• Low input voltage protection
• High input voltage protection
• Dimensions: 4.80" L x 3.60" W x 1.5" H

Sure Electronics PS-SP12151 300W 12V DC/DC Boost Converter Voltage Step-Up Board with TL494 IC

can 3 modules be wired in parallel to increase output power?

Asked by: Hannes74
It can’t be wired in parallel to increase the output power. Sure Electronics has a 500W Boost Converter, you can check to see if it can meet your needs.

Do you have a output voltage noise, output current noise, or output ripple spec on this product?

Asked by: audiocrossing
The output ripple is not high. It can work with the amplifier boards but will not affect the sound quality of the amps.

says 12v booster, but can take up to 27v input, can i use this safely to take 24v to 36v at about 4amps on the 36v side basicly i need to power a 100x2 amp that is asking for 36v for me to get 80x2 at 8ohms for a dayton shallow 10" sub or plate amp?

Asked by: Andrew123
The input voltage is 11V-27V, it can used to boost your 24V PSU to 36V. But just confirm if 24V is the steady voltage, if you are using it in some special application like car, you should be careful that some instantaneous high voltage will burnout the board.

Will this survive and provide constant voltage during engine cranks?  

Asked by: akh72
This is designed to accept an input from 11-47 volts DC, so it will survive peaks in voltage.

Ok, I have 3 of these boards. I apply 12 v to the 12v terminal and hook up a ground and nothing comes out of the output on all 3 boards. The LED lights up as soon as 12v is applied but no output voltage on the output side. What am I missing?

Can you make this turn on and off with the remote wire on a head unit like a traditional car audio amplifier?

Asked by: dan the man
Not without a relay circuit. The amp does not have a remote input like a normal car amplifier, so a relay would be needed in order for that to work the same way.
