Power supplies minimise waste heat

The GEN60-40, GEN150-16 and GEN600-4 models achieve 88% efficiency at 200V AC, while the GEN8-300's efficiency is rated at 84%.

Lambda has released a 1U 2.4kW version of its Genesys rack-mountable, programmable power supplies.

The first group of GEN 2.4kW models released include output voltage ratings of 0-8, 0-60, 0-150 and 0-600V.

The maximum output current for the lowest voltage range is 300A.

The input is continuously variable from 170-265V AC, in either single or three phase, and all units feature active power factor correction.

Lambda's GEN 2.4kW 1U achieves high efficiency for a programmable power supply, which not only minimises the generation of unwanted heat but also reduces wasted power.

The GEN60-40, GEN150-16 and GEN600-4 models achieve 88% efficiency at 200V AC.

For the high-current GEN8-300 model efficiency is rated at 84%.

The new shunt structure achieves an improved temperature coefficient (100 parts per million/C) of the output current.

Fan speed control helps to extend fan life and considerably reduce the fan noise at room temperature.

Safety features include Safe Restart/Auto Restart and Last Setting Memory.

With Safe Restart, the power supply returns to previous settings after power off, but with the output disabled.

Auto Restart enables the output after a power cut for unattended applications.

Last Setting Memory retains output voltage and current settings, remote or local mode, OVP and UVL, foldback current, baud rate and start up mode, without a battery.

The front panel controls include output on/off and local/remote selection.

The front panel may also be locked locally or by software command.

Common to the whole Genesys family is the built-in RS232/485 interface.

Using this digital interface up to 31 power supplies may be controlled in a daisy chain over the RS485 line.

Analogue remote programming is user-selectable from 0 to 5V or 0 to 10V via DIP switches on the rear panel.

Digital and isolated analogue interfaces are optional.

The optional IEEEdigital interface is IEEE-488.2 and SCPI-compliant and a wide selection of LabView drivers is available.

Isolated analogue programming options include either 0-5V and 0-10V, or 4-20mA control.

An optional LAN (LXI compliant) card is also available.

Higher power systems can be configured with up to four GEN 2.4kW modules.

Paralleling units for higher power is simplified with the master unit able to report total system output current.

As a result, the four units can appear as a single 9.6kW power supply, increasing flexibility for system designers.

The overall weight of each GEN 2.4kW module is less than 10kg and rack space is kept to the minimum, since all Genesys supplies are true "zero stack" with no space required between units.

CE marked in accordance with the Low Voltage Directive, Genesys conducted and radiated EMI conforms to EN55022-A, FCC-A.

Safety approvals include UL60950-1 and EN60950-1.

All models carry a five-year warranty.
