TDK-Lambda has added further models to its Genesys 3.3kW and 5kW compact 2U format programmable power supplies suitable for industrial applications that utilise high-power halogen heaters.

The new models complement existing models in the Genesys 1U, 2U, 3U and half-wide portfolio, which covers power ratings from 750W to 15kW.

The 0-200VDC output models, available in both the Genesys 3.3kW and 5kW, are ideally suited for applications related to the testing of solar cell arrays, and for use in electrolysing sulphuric acid in water purification plants.

Extending the Genesys 5kW range, models with 0-400VDC and 0-500VDC outputs offer an option for use with the manufacture and test of flat-panel television displays, where high-power, high-voltage DC supplies are a common requirement.

They are both ideal for industrial applications that utilise high-power halogen heaters, which typically require between 200V and 400V to drive them.

These power supplies have three-phase inputs for operation from 170-265VAC or from 342-460V, and the 3.3kW models are additionally available in single-phase versions suitable for operation from 170-265VAC.

The new models feature active power factor correction and extensive safety features, including user-selectable safe-start and auto-restart options.

With safe-start, the power supply returns to the last used settings after a power interruption, but with the output disabled.

With auto-restart, the supply resumes normal operation without intervention after a power interruption, thereby meeting typical requirements for unattended use.

Common to all Genesys models is a built-in RS232/485 interface.

Using this, up to 31 power supplies may be controlled in daisy chain over an RS485 line.

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

Other digital and isolated analogue interfaces are optional: the IEEE digital interface is IEEE-488.2 and SCPI compliant and a selection of Labview drivers is available.

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

An LXI-compliant LAN interface is also available.

Higher-power systems can be realised by connecting up to four units in parallel.

In advanced parallel configuration, the master unit reports total system output current, which means that the four units appear as a single power supply, increasing flexibility for system designers.

The power supplies are CE marked in accordance with the Low Voltage Directive, and 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.
