Designed to suit the needs of industrial users, the LZSa compact single-output power supplies from Lambda is being extended to include units with rated outputs of 500, 1000 and 1500W. All models in the range feature rugged construction, which helps to ensure reliable operation even in harsh environments, plus they have comprehensive protection against transients on the mains input.

Suitable for universal operation from AC supplies in the range 85-265V at 47-440Hz, and DC supplies in the range 100-400V, Lambda's LZSa power supplies have a nominal output voltage of 24V DC. User adjustment of the output voltage is possible from 18-29.4V, enabling it to be matched to the needs of the application. Remote sensing is also supported, so cable voltage drops can be compensated for.

LZSa supplies rated at 1000W are also available with a nominal 12V DC output.

All models in the range combine high operating efficiency with a superior thermal design, to give a long, reliable service life, even when operating continuously at the maximum recommended ambient temperature of 71degC. To demonstrate its confidence in the long-term reliability of the units, Lambda offers them with a five-year warranty as standard.

To facilitate their use in demanding industrial applications, LZSa power supplies incorporate overvoltage, overcurrent and thermal protection. They also feature opto-coupled transistor outputs to indicate AC fail, DC good and inverter OK, and a further output to provide a 200kHz synchronisation signal from the switching converter. Remote on/off control and remote output voltage adjustment are supported.

Fully compliant with EN 60950-1 and its equivalents, as well as FM 3600, 3611 and 3810, power supplies in the Lambda LSZa range are CE marked. In addition, they satisfy the requirements of EN 55022/EN 55011 Class B, together with EN 61000-6-6, for EMC performance.
