Lambda Offers Harsh-Environment 1000W & 1500W Power Supplies for Industrial and COTS Applications

SAN DIEGO, CA (Jan 7, 2008) - Lambda has extended its 500-watt LZSa series of industrial power supplies to include 1000 and 1500-watt supplies with a unique feature set and safety-agency approvals not commonly found in standard off-the-shelf supplies. A wide operating temperature range, compliance with MIL-STD-810E standards for shock and vibration, and the ability to operate in explosive gas atmospheres make these new LZSa1000 and LZSa1500 series supplies ideal for use in a variety of applications such as factory automation, computing, ATE (automatic test equipment), petrochemical, control systems and COTS (commercial-off-the-shelf).

lzsaThese rugged power supplies are available with a nominal output of 12V (LZSa1000) or 24V (LZSa1000/1500). They feature wide user-adjustment ranges of 10 to 15.75-volts and 18 to 29.4-volts respectively to accommodate non-standard voltage requirements. With integral fan-cooling they provide full-rated output power from -40°C to +60°C, derating linearly to 60% load at 71°C ambient.

The LZSa series accept a wide input range from 85 to 265VAC, 47 to 440Hz and have active power factor and harmonic correction. They also comply with SEMI-F47 standards for input droop down to 100VAC at full load.

Output ripple and noise is a low 75 millivolts peak-to-peak, and the unit is designed to provide 20-millisecond hold-up and ride-through to avoid nuisance tripping during transient electrical interruptions.

The LZSa1000/1500 supplies are equipped with remote on/off, front panel mounted voltage adjust potentiometer, remote resistance or voltage programming and user-adjustable over-voltage protection. Status signals and controls include DC good, AC Fail, Inverter OK, 200 kHz sync signal, and active current share. In addition, on the front panel a green LED indicates output-good and a red LED indicates an overvoltage or overtemperature condition.

These 1000/1500-watt supplies come in a compact 5.62 x 4.75 x 10.5-inch package and meet Class B EMI standards (both radiated and conducted) and are safety-approved to UL60950-1, EN60950-1, UL508, and Factory Mutual: FM3600, FM3611 and FM3810 specifications. They also comply with the Ring Wave Lighting Surge Test per IEEE C62.41 (6kV/30 Ohm, Criteria A) and Immunity Standards per EN61000-4-X. All units are RoHS-compliant and carry the CE Mark.

The LZSa1000 and LZSa1500 are available now, priced at $825 and $1250 each in 100-unit quantities. More information can be found at Lambda's Web site: www.lambdapower.com.
