12V or 24V to , 2V, 3V, 4V, 5V, 6V, 7V, 8V, 9V, 10V, 11V, 12 Volt DC/DC Converter UL listed

Very reliable, inexpensive switchmode, regulated DC/DC converter adjustable to various voltages between 1.5V and 11V. Maximum 5 Amp output.

This is a single output DC/DC converter with barrel connectors for input and output. Input voltage up to 34 volts. It is adjustable by an externally accessible potentiometer between 1.5V and 11V as long as the input voltage is at least 0.5V higher than the output voltage. These switchmode voltage reducers can power a wide variety of DC input products from 12 volt and 24 volt trucks, heavy equipment, and aircraft cigarette lighter power points.

The PST-DC2920L DC converter works fine in either 12 volt or 24 volt vehicles.

PST-DC2920L 5 Amp DC/DC converter with two cords and barrel connector assortment		Quantity 1-20 21-100 101-500 501+ Price Each $65 $59 $55 $49
ZHJX002 To adapt the barrel connector to screw terminals on the INPUT cable		$2.50 each
SDY-C53F-2.5 5.5 x 2.5 mm barrel socket To adapt the barrel connector to screw terminals on the OUTPUT cable		$2.50 each
This cigarette lighter plug adapter has a 2A fuse, so it is applicable to low power applications. For example if the input voltage is 24V then 2Amps*12Volts*0.8efficiency = 19 Watts output maximum.		Price $2.25 each
PST-WX25-10 Optional 10 connector kit that fits only on the input cable (see below for sizes)		$5.99
