EPS/EL Electronic Load 400-7200 W

EPS/EL Electronic Load 400-7200 W The microprocessor controlled programmable »EPS/EL« of EPS Electronic Power Supplies are electronical loads satisfy practically every need of modern laboratories and industry, so e.g. also for Lithium (E-Vehicle) and Ultracap discharging.
Besides the operation modes Constant Current and Resistance, Voltage and Power other settings are additionally effective to protect the test equipment. For example, constant current can have a maximum power setting while constant voltage, power or resistance can have a maximum current setting.

The easily readable graphic display shows a clear representation of set values with which the user is guided by a clear menu and rotary knobs. The standard range provides loads from 400W until 7200W or upon request, cabinets up to 100kW input power at 7000 A. The input voltages are even up to 750V. It is possible to switch in static operation or in dynamic operation. In the battery test mode, a battery can be discharged with a constant current, - power or - resistance until the battery voltage reaches an adjustable final discharge voltage. If this threshold is exceeded, the load input is automatically switched off (deep discharge protection). The discharge time and consumed charge (Ah) are measured and displayed.

The "System Bus" at the rear side of the »EPS/EL9000« has a number of functions, such as remote sense input, switching of the internal regulation speed and the Share bus input to build a two quadrant operation system with laboratory power supplies of the »E/PS/I 9000« or »E/PS/I 8000«.
Typical applications i.e. for the 2Q operation 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.

The electronic loads in the »EPS/EL-HP« series offer an upgrade by incorporating a high performance cooler and blower.

The load can be controlled directly from a PC by optional digital Plug&Play inferfaces like USB, GPIB, RS232, CAN and Ethernet. Included there is a Windows Software (USB, RS232) which provides control and monitoring, data logging and automated sequences. The optional water cooling has the advantages that there is no hot air exhaust on the device and no heat accumulation as well as significantly lower noise and 100% permanent power available.
