DESCRIPTION
The DCDC-500-48-12 is a DC-to-DC converter that is capable for 500 watts of power. It has isolated inputs and outputs, so it
can be used in positive ground installations. The fan is thermostat controlled to protect against heat damage. The input voltage range
has a minimum of 19 VDC and a max VDC of 72. All of the DCDC-500 models come equipped with three layers of protection short
circuit, over load, and over temperature protection.

INSTALLATION WARNING
The individual user should take care to determine, prior to use or installation, whether this device is suitable, adequate or safe for the
use intended. Since individual applications are subject to great variation, DuraComm makes no representation or warranty as to the
merchantability, suitability or fitness of these units for any specific application.
DO NOT block any of the cooling vents on the sides and always allow adequate ventilation by not installing the unit inside tightly closed
spaces. Physical mounting position is not critical but the cooling vents must not be blocked. Make certain the input voltage is the
correct voltage BEFORE applying DC power.

- Page 2 CONDUCTOR PRETREATMENT All kinds of copper conductors can be clamped without treatment. DO NOT solder tin stranded conductors. The solder yields and fractures under high pressure. The result is increased contact resistance and excessive temperature rise. Additionally, corrosion has been observed due to the fluxes. Notch fractures at the transition from the rigid tinned part to the flexible conductors are also possible. Ferrules can be used as a protection when wiring stranded conductors.
- Page 3 DuraComm, at its option, will repair or replace the faulty product or parts thereof, which, after examination by DuraComm, prove to be defective or not operational according to specifications in effect at the time of sale to the initial end user.
