The ELP-3340G series of DC loads feature a dedicated LED simulation mode. This is in addition to the standard constant current, resistance, voltage and power operating modes.
A full dynamic mode is also provided. This allows the unit to simulate real world load conditions by switching between current levels and adjusting the rise and fall times.
- Control Signal for TRIAC and PWM Dimming Test
- LED Forward Bias and Resistance Simulation
- CC, CR, CV, CP, LED and Dynamic Mode
- Short Circuit, OCP and OPP Tests
Operating Ranges and Features
High resolution setting and measurement is provided with dual ranges ensuring precision operation at low values. The 5-digit LCD shows voltage, power and current simultaneously.
The ELP-3340G are also built with a fast response dimming control function. This provides a 0-10V signal to the LED driver to check its dimming control. A range between DC to 1kHz at a duty cycle of 1-99% is possible.
The front panel memory function allows test set ups and routines to be easily saved and recalled.
The specialised LED Mode is designed to test LED Drivers / LED Power Supplies. The ELP-3340G can be used to simulate a single LED or a string containing up to 90 LEDs. The forward bias voltage (Vd) and operating impedance (Rd) can be adjusted along with the nominal operating voltage (Vo).
In addition to the standard short test function a dedicated LED short test signal provides a 12Vdc output for connection to an external relay.
APPLICATION SPECIFIC GUIs
The ELP-3340G is available with a current waveform generator (option /9923). This allows the electronic load to sink different levels of energy over time. These load profiles can either be created on a PC using the waveform generator software, or imported from oscilloscope data.
Form Factor and Enclosures
The ELP-3340G are housed in a single slot chassis (option /3302F), dual slot chassis (option /3305F) or four slot chassis (option /3300F). The mainframes provide the AC power conversion, cooling and the optional computer interfaces. Please see the separate mainframes datasheet.
If your test requirement is short term, we have a wide range of DC electronic loads in our rental range.
While primarily aimed at the testing of LED drivers, the ELP-3340G modules are also ideal for general use.
