The electronic high performance power supplies of the »E/PSE 9000 3U« series of EPS Electronic Power
Supplies are especially suitable for test systems and industrial controls due to their compact
construction in a 19" enclosure with 3 height units (3U).
DC output voltages between 0-40V (SELV) and 0-1500V, output currents between 0-40A and 0-510A
and output power ratings of 0- 3.3kW/5kW/6.6kW/10kW/15kW are available.
Actual values, set values, status and alarms are clearly represented on the blue LCD-display.
For remote control using a PC or PLC the devices are provided as standard with an Ethernet and USB-B
slot on the rear side as well as a analog interface. All interface are galvanically isolated to the unit up to
Thus the power supplies may, for example, be operated with other power supplies or even other types
of equipment or controlled by a PC or PCL, all using the digital interfaces.
In addtion, the devices offer as standard the parallel switching in Shared Bus operation for constant
current sharing and for extension of the total power of up to 480kW and up to 5100A per 42U rack.
Also you have the possibility to connect the compatible power supplies via a Shared Bus, in order to
create a so-called two-quadrant system. Typical applications i.e. for the source-sink principle are: battery
test with automatic charge and discharge cycles, automotive electronic tests with simulation of
transients (like voltage break-ins during engine starts) and cyclic charging and discharging of capacitors.
A series operation is also possible with max. potential shift of 400V against PE on any DC minus pole.
All models are controlled by microprozessors. These enable an exact and fast measurement and display
of actual values.
With the lock push button the controls can be locked, in order to protect the equipment from
In order to achieve rapid voltage changes with minimal ramp up and down times, the filter capacity can
be reduced with the option High speed »EPS/HS«. It results in ramp times in the range of microseconds.
Models with a nominal output voltage of 200V or higher include a discharge circuit for the output
capacities. For no load or low load situations, it ensures that the dangerous output voltage can sink to
under 60V DC in max. 10 seconds after the DC output has been switched off (SELV according to
Further options are water cooling (up to 200V) and calibration with protocol.
