Lambda packs 15kW into 3U

Despite their small size, the new Genesys™ 3U supplies are available with output capacities up to 15kW – a rating which would, until now, have required the use of 5U power supplies. Further space savings are made possible by the true zero stacking capability of the new supplies, which means that multiple units can be installed in standard racks without the need to leave gaps between them.

Where applications require more than 15kW of output power, up to four Genesys™ supplies can be operated in parallel in a master/slave configuration. For convenience of monitoring and control, this arrangement behaves exactly as if it were a single power supply – reporting, for example, the total load rather than the individual load of each power supply.

To ensure straightforward and economical interfacing with external equipment, the new power supplies feature an integral RS 232/RS 485 interface as standard. To further enhance connectivity, USB, LXI-compliant LAN, and IEEE488.2 SCPI multi-drop interfaces can be fitted as options. The power supplies also provide analogue control interfaces, as well as offering independent remote enable/disable and on/off control.

Designed for worldwide use, power supplies in the Genesys™ 3U range from Lambda have a choice of 208V, 400V and 480V three-phase inputs. They can be supplied with output voltages from 7.5V to 600V and, depending on the voltage, with output currents up to 1000A. All types feature programmable over-current and over-voltage protection and all have integral over-temperature and phase-loss protection features.

Genesys™ 3U power supplies incorporate passive correction on all inputs, and have a power factor of 0.88. They offer excellent EMC performance in line with the EN61000-4 series of standards and their international equivalents, they are UL recognised, and versions with 208V and 400V inputs carry the CE marking as evidence of conformance with the appropriate European LVD and EMC regulations.
