CAUTION: This adaptor is supplied on the basis of the user determining the suitability for the purpose for which it is to be used. Do not use in a moving vehicle without the consent of the vehicle manufacturer. Do not use for aviation or marine applications without our written agreement. Do not use for life dependent applications. The negative input lead is connected to case unless specified as isolated at time of purchase.
SPECIFICATION:
• VERY HIGH CONVERSION EFFICIENCY. • HIGH OUTPUT POWER IN COMPACT SIZE. • CHARGE ANOTHER BATTERY AT 12, 24, 36 OR 48V. • USE 12V OR 24V OR 36V OR 48V EQUIPMENT. • REMOTE ON / OFF CONTROL. • LOW BATTERY ALARM WITH AUTO SHUT-OFF . GENERAL DESCRIPTION: A rugged converter, generating 13.8V or 27.6V or 41.1V or 55.2V DC (lead acid float voltages), capable of powering most battery equipment when supplied from 12, 24, 36 or 48V batteries with up to 440 watts of continuous power.
The output has a constant current characteristic so that lead acid batteries may be charged to provide a dual voltage system.
The unit incorporates an electronic relay to turn it on/off remotely, driven by a control input, which may be supplied from any low current switch.
The input and output are ohmically isolated, making installation very simple. Input can be isolated from chassis by up to 100V.
The unit is packaged in a powder coated folded metal box. Input wires enter on one side face, and an outlet terminal block is mounted on the top face. Flanges are provided for mounting at each end.
