The 63000 series programmable DC electronic loads are reliable, precision instruments primarily designed to test switching power supplies, A/D power supplies, power electronic components, adapters, 3C batteries and chargers. Its maximum 350W rated power makes it suitable for testing numerous types of lower power devices.

Static and Dynamic Load

The 63000 Series electronic loads operate in constant voltage, current, resistance, power or impedance modes to satisfy a wide range of test requirements.

  • Programmable parameters: Current high/low level, T1/T2, rise/fall rate and execution times.
  • Execution time setting range is 1 ~ 65,535.
  • 150V model’s current rise minimum response time is 20μs.
  • Suitable for testing D/D converters.
  • One shot impulse current is loaded when it is set to execute once, which is very suitable for testing instant large withstand current of batteries

CZ Mode

To avoid charging the motherboard capacitors when the switching power supply powers on with surge current triggering the power supply over current protection mechanism making the power supply fail to turn on successfully, the power supply requires conducting a turn on capacitive load test. The 63000 series provides CZ mode for turn on capacitive load simulation to tackle this testing demand. CZ mode simulates the actual inductance, impedance and capacitance for loading making the load current closer to real conditions.
