LED Load Simulator

63110A/ 63113A/63115A - Chroma ATE Inc.

As shown on the V-I curve in figure 1, the LED has a forward voltage VF and a operating resistance (Rd). When using a resistor as loading, the V-I curve of the resistor is not able to simulate the V-I curve of the LED as shown in blue on figure 1. This may cause the LED driver to not start up due to the difference in V-I characteristic between the resistors and the LEDs. When using Electronic Loads, the CR and CV mode settings are set for when the LED is under stable operation and therefore, is unable to simulate turn on or PWM brightness control characteristics. This may cause the LED driver to function improperly or trigger it’s protection circuits. These testing requirements can be achieved when using a LEDs as a load; however, issues regarding the LED aging as well as different LED drivers may require different types of LEDs or a number of LEDs. This makes it inconvenient for mass production testing.

63200E Series - Chroma ATE Inc.

The 63200E series are high power DC loads that include a choice of three operating voltages, 150V, 600V and 1,200V, with power levels from 2kW to 24kW and up to 2,000A in a single unit. Power levels can increase up to 240kW when multiple units are paralleled.These high power loads are designed for testing a wide range of EV products including DC charging stations, car battery discharge, on board charger power components, and other power electronics components. With its high power capabilities, parallel control and dynamic synchronization functions make this load ideal for automotive batteries, fuel cells and more. The 63200E load's master/slave control application enables units with the samevoltage specification to be used in parallel and synchronized dynamically to meet the power testing requirements. In addition, a 255-set data storage function has been built-in for recall of the stored settings at any time. When used in automated testing, the save and recall functions can save a great deal of time.

6330A series - Chroma ATE Inc.

The 6330A family offers 8 types of modular loads with power ranging from 30 watts to 1200 watts, current from 0.5mA to 240A, and voltage measurement from 0.5mV to 500V. Each load is isolated and floating, programmable in dual current range and measuring voltage range, and capable of synchronizing with other modules for control operating. The load can be operated in constant current, constant voltage, and constant resistance. With Synchronic parallel control capability, 6330A series loads allow users to parallel and synchronize more than one load together from an internal loading control signal. This feature provides synchronic dynamic loading test for multi-output power and high power test solution. Real time measurement of voltage, current, is integrated into each 6330A load module using a 16-bit precision measurement circuit. The user can perform on line voltage measurement and adjustment, or simulate short circuit test using the simple keypad on the front panel.
