Bench Power Supplies

Powerfactor’s range of bench, or laboratory power supplies cover an extensive range with output power ratings from 80 watts to 9,000 watts.
Designed and produced with quality , reliability and value for money in mind these units offer top class performance and are equally at home in development workshops, schools and universities or laboratories.

We also catalogue electronic loads from 400 watts to 3600 watts

Electronic Loads 400 - 3600 watts

NEW - EA-PSI 9000 Series
New, feature packed digital and programmable laboratory power supplies of the series EA-PSI 9000 are based on the series EA-PS 9000. The new concept of the power stage provides to the user either a high output voltage or a high output current. The output values are limited by the output power. These power supplies are designed for engineering laboratory and complex industrial applications. The user-friendly and interactive menu guidance simplifies the configuration of user profiles and function sequences. Complex applications can be put into practice very quickly and simply. Function sequences or user profiles can be edited/stored for a better reproducibility of tests. The integrated monitoring functions with adjustable delays simplify the test assembling because no external monitoring circuits are required.

Alarm management: occuring errors, like over temperature, can be signalled differently ( selectively as signal sound, as display element or shutdown of the output).

Function manager: up to five sequences (repeatable sections) with ten parameter pairs each (voltage-time or current-time) and extra parameters per sequence, like inner resistance (only with option inner resistance control), maximum output power or number of repitions can be set. The function can be put in, edited and saved at the unit. The order of how the sequences are processed can also be determined.

User profiles: up to four profiles, editable by the user at the unit, can be stored and recalled very easily. They contain various settings of the unit, for instance voltage limitation setup, overvoltage threshold etc.

2 slots for pluggable cards: the cards are interfaces to common systems like USB, CAN, GPIB or RS232. By these cards multiple units can be networked, programmed, remotely controlled and monitored. USB can even realise a so-called gateway function. This means, one power supply (master unit) can be linked with a PC by RS232 (serial) and further power supplies are linked from the master and to each other by CAN bus, for instance. The same with USB to CAN gateway functionality. The cards can be equipped as desired and are delivered with ready-to-use LabView components.

Master-slave operation: Special feature is the display of the total current resp. total voltage of all linked power supplies on the master's display using the System Link mode. It requires one of the new interface cards for USB or RS232. Without one of these cards only the normal master-slave operation is provided, at which the actual values are displayed on each unit.

LabView support: all optional interface cards (except for the analogue interface) are supported by the "ready-to-use" LabView VIs (included in any interface card package), which serve to easily implement multiple power supply units into existing networks, bus systems and LabView applications.

Options:
Inner resistance control: the inner resistance will be adjustable at the unit ( front potentiometer), whereas the power limitation is rigid and set up by a value in the menu.

Interface cards: pluggable cards for USB, RS232, CAN or GPIB (on request), as well as an analogue, galvanically isolated interface card (on request) with programmable digital in- and outputs. These cards provide supervision, measuring and control features for up to 30 units and can also be used to network multiple units.
