NO-BREAK, 1.5-KW, DIRECT-CURRENT, 22 - TO 28-VOLT POWER SUPPLY,

Abstract

This report presents the facts and conclusions concerning an engineering model of a no-break, 1.5-KW, direct-current, 22- to 28-volt power source. The report concludes that: (a) The use of an automotive-type, alternator-battery power supply is technically feasible for equipment designed to operate within a voltage range of 22 to 28 volts; (b) Standby power can be provided by the use of lead-acid batteries; (c) With the generator set operating at 2600 and 3600 rpm, full-load and system noise level being measured, the average difference was 2 decibels lower at 2600 rpm--approximately a 33% reduction in noise level for the lower speed; (d) Where a constant terminal voltage (27.5 plus or minus .5) is required, a direct-current voltage inverter can be added to the system to maintain a 27.5-volt terminal voltage when power is taken from the two 2HN batteries.
