Description

Manufacturer Part Number: PS-SP12148

The PS-SP12148 500 watt 12V DC/DC boost converter voltage step-up board, with TL494 IC, works perfect for increasing voltage to high power amp boards for use in cars or other 12 VDC applications.

Key Features:

• Designed for stepping 12V up to as much as 48V for using amplifier boards in your car
• Fine-tune voltage adjustments and regulated by the TL494 IC
• Small size for creating a hidden audio system (amp boards required)
• Under and over input voltage production
• Input line with fuse protection

Overview:
Sure Electronics PS-SP12148 500W 12V DC/DC Boost Converter Voltage Step-Up Board with TL494 IC

This 500 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 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 further protection is provided by two 40A 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.
