1000 and 1500W power supplies operate in explosive-gas atmospheres

Adding to the vendor’s 500W LZSa series of industrial power supplies, the 1000 and 1500W power supplies target industrial and commercial applications. Suiting harsh environments, the devices comply with military standard 810E for shock and vibration and operate in explosive-gas atmospheres. Available in 12V in 1000W or 24V in 1000 or 1500W, the power supplies feature 10 to 15.75V and 18 to 29.4V user-adjustable ranges, respectively. Integral fan-cooling provides full-rated output power from –40 to +60°C and derating linearity to a 60% load at a 71°C ambient temperature. Accepted input ranges include 85 to 265V ac and 47 to 440 Hz, and the devices feature active power-factor and harmonic correction. The power supplies complying with SEMI-F47 standards for a 100V-ac input droop at full load and provide a 75-mV p-p output ripple and noise. Providing 20-msec holdup and ride-through allows the devices to avoid nuisance tripping during transient electrical interruptions. Available in 5.62×4.75×10.5-in. packages, the LZSa1000 and LZSa1500 cost $825 and $1250 (100), respectively.
