PS915 24/12VDC Isolated Converter
Failure of a linear unit can often result in the main supply being directly connected to expensive radio equipment. Since there is no connection between the electronics and the housing, the supply is fully floating. This enables the equipment to be operated on positive earthed vehicles or vehicles which have earth switching for battery isolation. Linear supplies can often cause problems when battery isolation switches are operated incorrectly and an earth return is provided by the battery wiring. Inadvertent starting of the motor under these conditions can cause damage to the wiring harness.
An optional timing circuit application is available which interlocks the power supply with a vehicle's ignition system, disconnecting the unit 45 minutes after the ignition is switched off.
The PS915 is fully protected, is very efficient (80% at 10A output) and draws little current on stand by, typically less than 30mA.
