High Reliability

  • Protective circuitry provides over-current, over-voltage, over-power, over-temperature and reverse polarity protection to ensure the protection of the electronic load;
  • A high-speed, power limiting circuit can limit input power rapidly when it is overloaded, thus there is no need to interrupt testing. Equipment adaptability to complicated operational environments is thereby greatly enhanced.

Great Performance

  • Circuit improvement greatly enhances the dynamic response of CR mode and widens the application scope of that mode;
Array electronic load
  • Minimum operating voltage is less than 0.6V at the load's full rated current. With optional low-voltage testing devices, the maximum current can be achieved even though the input voltage is 0V. This is especially suitable for fuel cell, solar cell and other new energy test applications;
  • By adopting an optimum design of calculation method and high-speed hardware circuitry, the D/A conversion rate can reach 100kHz. The overall smoothness of slope control has been raised, meanwhile, the timing precision and resolution of dynamic test and sequential test have also been improved;
  • The 24 bit A/D and 17 bit D/A converters incorporated, provide this equipment with greatly enhanced setting and measurement resolution.

Multifunction

  • Equipped with four basic test functions: CC, CV,CR, CP;
  • High-speed transient operation with separate high/low lever time and rising/falling time control;

  • Powerful sequential test function; with a minimum step time of 10us; and a maximum step time of 10000s. Cyclic numbers can be adjusted freely and a sequence can be chained to another sequence to achieve even more complex test procedures;
  • Providingshort-circuit test, battery discharge test and other auxiliary functions;
  • Remote input terminal and external trigger input terminals are provided. The remote measurement can monitor the input signal automatically, and it is not necessary to change wiring or modify settings during operation;
  • 10 groups of setup parameters can be saved, and providing automatic uploading of preset parameters;
  • By supporting SCPI, it is easy to build an ATE (automatic test equipment) system that works with other programmable instruments via optional RS232, USB and GPIB interfaces.

Easy Operation

  • Design optimized for portability and rugged reliability;
  • Logical keypad design and convenient test operation;
  • Easy-to-set test parameters coupled with a powerful sequence editing function;
  • All electronic calibration - therefore no need to dismantle the equipment-chassis;
  • Firmware can be updated online.

Specifications

*1. Maximum continuous power available is derated linearly from 100% of maximum at 40 degree, to 75% of maximum at 55 degree.

*2. Conductance (S) = 1 / Resistance (Ω)..

*3. The set level is 10 times larger than the slew rate in CCL mode.

*4. The actual transition time is defined as the time required for the input to change from 10% to 90% or from 90% to 10% of the programmed excursion.

*5. Transient frequency depends on the time for high/low level and rising/falling edge.

*6. Full remote control via RS232 with optional GPIB and USB.
