EL Series Electronic Loads
Kepco's EL Series is a line of modular aircooled, DC electronic loads used to test power sources such as batteries, power supplies, generators, chargers, fuel cells, etc, that offer a superior solution for all applications.
All EL loads are linear designs, meaning no switchmode noise to worry about. They are controlled from either the front panel, analog signals or digitally (USB, RS 232, GPIB, Ethernet). A graphical user interface (GUI) using LabView makes for easy programming that allows intuitive use.
Power ratings start at 1KW; standard models have maximum test capabilities of 50, 200, 400 and 600 volts. High current and power operation are achieved via parallel connection in a master/slave configuration. Individual modules are capable of up to 5KW and 800 amperes.
The EL Series offers unique Functional Modularity. Functional Modularity allows the load to be retrofitted to increase load power/current as required for undefined future applications. Purchase the capability needed today with assurance of future power/current upgrades. The result is an Electronic Load maximizing the most important specification: VALUE = $/Watt. When the requirements increase, the load may be upgraded.
The EL series can provide fast load transitions, changing the output from proportionally sinking to blocking and vice versa at a settling time rate of up to 500μS. The settling time can be adjusted, depending on the application at hand. Kepco's Application Note EL 001, EL Electronic Load Fast Timing Adjustments gives details and tips as to the best way to optimize the adjustment for fast load transitions.
OVERLOAD CAPACITY
|
Short term overloads (spikes) from the source being tested may go beyond the rated continuous capacity of the EL load. These short term spikes can be absorbed as illustrated in the Overload Capacity graph shown at the left. Kepco’s EL load features programmable Peak Pulse Power that allows a spike load to be put on the source. |
All EL loads operate as master or slave and come with or without front panel control and readouts. Up to 15 additional loads can be driven with one acting as a master.
Four Dual channel models include two completely independent 1KW loads in a single chassis. These can be conveniently arranged in master/slave configuration for 2KW capability when needed.
Kepco's Series EL Electronic Loads provide 1:1 replacement solutions for fielded electronic loads such as Series NH 4700, NH4760, NH 4312 and NH 4350 that are hard to find or unavailable. (Download specs for comparison of Kepco Series EL to fielded NH 4700, NH4760, NH 4312 and NH 4350)
EL are CE Marked per the LVD, EMC and RoHS 2 Directives. See applicable Declaration of Conformity.
