|
A road research vehicle is fitted with several touch screens, video cameras, network switches, etc. Originally these were powered from 230V ac mains plug adaptors which tend to occasionally fall out with the vibration from road imperfections. Two variants of this power supply have been commissioned, each to power up to 12 low voltage loads with a total output of 180W per unit.
These supplies operate from an auxiliary 12V vehicle battery and have input surge and low voltage protection followed by isolation and output filtering circuits. There are appropriate secondary regulators to supply various voltage loads. The converters are designed for high efficiency to operate in the ambient temperatures experienced in a vehicle parked in the sun. The units are ruggedly built to survive the punishment of vehicle chassis mounting. Key FeaturesModular construction. Can be mounted upright or upside-down. Isolated from vehicle battery. Protected against vehicle voltage spikes, overvoltage, undervoltage and load dump. Wide choice of output voltages available. Up to 12 outputs. |
