This product is order related with an standard delivery time of approx. 5 - 6 weeks. Orderable in our Online Shop.
The microprocessor controlled laboratory power supplies of series EA-PS 5000 A offer a set of useful standard features, which can facilitate operation. Set values, actual values and status are clearly displayed at the same time on the blue, illuminated LCD, in order to have them at one glance. The implemented supervision features for all output parameters can help to reduce test equipment and make it almost u unnecessary to install external supervision hardware and software. The clearly arranged control panel with its two knobs and five pushbuttons enables the user to handle the device easily with a few touches of a finger.

The equipment uses an active Power Factor Correction (short: PFC), enabling worldwide use on a mains input from 90 VAC up to 264 VAC. Models with 1.5 kW will derate their output power to 1 kW below input voltages of 150 VAC.
AUTO-RANGING POWER STAGE
All models are equipped with a flexible auto-ranging output stage which provides a higher output voltage at lower output current, or a higher output current at lower output voltage, always limited to the max. nominal output power. The maximum power set value is adjustable with these models. Therefore, a wide range of applications can already be covered by the use of just one unit.
DC output voltages between 0…40 V and 0…200 V, output currents between 0…2 A and 0…40 A and output power ratings between 0…160 W and 0…640 W are available. Current, voltage and power can thus be adjusted continuously between 0% and 100%, no matter if manually or remotely controlled (analog or digital). The output terminals are located on the front side of the devices. There is furthermore an additional output on the rear side on a screw terminal.
For protection of the equipment connected, it is possible to set an overvoltage protection threshold (OVP), as well as one for overcurrent (OCP) and overpower (OPP). As soon as one of these thresholds is reached for any reason, the DC output will be immediately shut off and a status signal will be generated on the display and via the interfaces. There is furthermore an overtemperature protection, which will shut off the DC output if the device overheats.
DISPLAY AND CONTROLS
Set values and actual values of output voltage and output current are clearly represented on the display. Set values of voltage, current and power, as well as the protection thresholds (OCP, OVP) can be adjusted using the rotary knobs. To prevent unintentional operations, the knobs can be locked.
PRESETTING OF OUTPUT VALUES
To set output values without a direct reaction to the output condition, the set values are also shown on the display, positioned below the actual values. With this, the user can preset required values for voltage, current and power. It is done by using the rotary knobs.
The device can store 9 different sets of preset values for voltage, current, power, OVP (adjustable overvoltage protection) and OCP (adjustable overcurrent protection). These can be recalled easily by the push of a button and help to avoid constant adjustment of the output values.
- Safety adapter set (max. 32 A, 2 pcs. red/black), mounted on top of the DC output screw-clamp terminal, used to achieve a non-contact safety socket. For 4 mm Büschel plug.
