Alfatronix DD12-24VDC “Up” Voltage Converters are a requirement when installing 24V equipment into 12V systems. DD12-24VDC “Up” Voltage Converters range from 72 W (3A output) to 600 W (25A output). Designed for fast installation and long-term reliable operation. Typical applications include the installation of 24V equipment on 12V vehicles and installation of specialist equipment requiring higher operating voltages. The latest addition to the DD12-24V range includes two high current (17 and 25 Amps output) units.
Features:
- up to 93% efficiency
- practically all components are mounted using computer controlled surface mount technology (SMT)
- a robust product with low component mass
- new casing profile designed for maximum heat dissipation
- mounting cradle that allows the unit to be fully wired before “clicking” into place
- faster installation time and long-term vibration withstanding capabilities with no risk of screws falling out
- aluminium casings with polycarbonate endcaps and three point mounting cradle
- 400W and 600W units occupy a larger heatsink casing and utilise the heavy duty Phoenix connector (Installation through the larger four point ‘I’ shaped mounting cradle.)
- available in standard IP53 format or the more robust IP65 versions (add –RU to the product number)
