Programmable Electronic DC Load, 600W/80V/45A
The Elektro-Automatik EA-EL 9000 T are programmable DC loads with an easy-to-use touchscreen and built-in function generator. The EA-EL 9000 T are available in three power ratings, as shown below:
Model | Power | Power @ 40°C | Voltage | Current | Resistance | UMin for IMax (1 |
EL 9080-45 T | 0...600 W | 0...550 W | 0...80 V | 0...45 A | 0.12...40 Ω | ~ 2.2 V |
EL 9200-18 T | 0...500 W | 0...500 W | 0...200 V | 0...18 A | 1...340 Ω | ~ 2 V |
EL 9500-08T | 0...400 W | 0...400 W | 0...500 V | 0...8 A | 6...2000 Ω | ~ 6.5 V |
(1 Minimum DC input voltage to supply for the load to achieve the max. input current
All models support the four regulation modes constant voltage (CV), constant current (CC), constant power (CP) and constant resistance (CR). The core of the control circuit is a fast microprocessor that provides helpful features, including a true function generator with common functions such as sine, rectangle or triangle waves, as well as an arbitrary function. The color TFT touch panel offers the intuitive manual operation, similar to smartphones and tablet computers.
Response times during the control of the devices via analog or digital interface have been improved by ARM processor-controlled hardware, compared to older electronic load series.
Display and handling
Set values and actual values of input voltage, current and power are clearly represented on the graphic display. The color TFT screen is touch-sensitive and can be intuitively used to control all functions of the device with just a finger.
Set values of voltage, current, power, or resistance can be adjusted using the rotary knobs or entered directly via a numeric pad. To prevent unintentional operations, all operation controls can be locked.
