SPECIFICATION: INPUTS Nominal Voltage:
Input Voltage Range: Current, No Load:
Efficiency (approximate): Low Battery Alarm: Battery Low Latch Off:
12V or 24V or 36V or 48V Battery by model. Nominal – 11.7% to +16.7% 0.5A, 0.4A, 0.3A and 0.25A across range. 85% Nominal – 12.5% Nominal – 20%
• VERY HIGH CONVERSION EFFICIENCY. • HIGH OUTPUT POWER IN COMPACT SIZE. • REMOTE ON / OFF CONTROL. • LOW BATTERY ALARM WITH AUTO SHUT-OFF .
GENERAL DESCRIPTION: A rugged converter, generating a range of DC outputs when supplied from 12, 24, 36 or 48V batteries with up to 440 watts of continuous power.
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.
OUTPUTS Voltage (10% Load): Line Regulation: Load Regulation: -
Low Frequency Ripple: Current Limit: On/Off Control: -
GENERAL Protection:
Nominal + 100mV ±50mV. < ± 0.05V for a 10% input change. <-0.1V for a 10% to 90% load change. Less than 50mV pp. Nominal plus 10%, ± 7%. The unit will draw less than 0.1mA until voltage (3V to 72V) is applied to the control input.
Over-current and short circuit output limit plus input fusing.
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.
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.
