Programmable DC Electronic Load Model 63000 Series

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

The 63000 Series offers the operating voltage 150 models, with 250W and 350W power levels up to 60A in a single unit. Their compact and light weight design make these loads easy to move around which is ideal for R&D and design validation.

Each model of the 63000 Series has unique user-def ined waveform (UDW) funct ion capable of simulating real-world custom waveforms. In addition, a data storage function has been built in for saving and recalling up to 100 stored settings at any time. For automated testing, these save and recall functions can save a great deal of time.

The 63000 Series has 3 power ranges that can precisely measure the voltage and current in real time. Since short circuit testing is a critical test item, the 63000 provides short circuit simulation to effectively address application demands for power and automated testing.

With the LCD and rotary knob, the 63000 loads offer versatile front panel operation. For remote operation, users are able to control each model via standard USB or optional Ethernet/LXI and GPIB interfaces. PWM fan speed control has been embedded to reduce ambient noise.

The 63000 has been equipped with over current, overpower, and over temperature protections as well as over voltage and polarity reverse alarms to improve product reliability. These DC loads are reliable, precision inst ruments ideal for design validation testing and automated test system integration.

Dynamic Load
  • Programmable parameters: Current high/low level, T1/T2, rise/fall rate and execution times.
  • Execution time setting range is 1 ~ 65,535.
  • Suitable for testing D/D converters.
  • 150V model’s current rise minimum response time is 20μs.
  • 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 (Available in May, 2018)
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.
Three Ranges and High Precision Measurement
  • High, medium and low three operating and measurement ranges.
  • Voltage, current and power measurement specifications:
    • 0.02%+0.02%F.S. accuracy for voltage
    • 0.05%+0.05%F.S. accuracy for current
    • 0.1%+0.1%F.S. for power
User-Defined Waveform (UDW) (Available in May, 2018)

The conventional way of loading a current waveform is through DAQ cards or function generators. The 63000 Series provides an enhanced feature, User Defined Waveform (UDW), to simulate the actual current profiles and waveforms. Each load is capable of storing up to 10 sets of waveforms with each containing up to 1.5 million data points in the built-in flash memory. It also provides voltage peak measurement during actual loading conditions avoiding the need for an oscilloscope which saves time and cost.

Battery Discharge Testing (Available in May, 2018)
  • Three discharge modes: CC, CR and CP.
  • Set cut off voltage and time (1~100,000 sec.) to stop loading and ensuring the battery is not damaged due to over discharge
  • Measures the battery discharge power (WH, AH) and total discharge time
  • Applies to super capacitor for discharge time testing and other related applications
 
Battery Discharge Power (WH & AH) Calculation
Program Sequence

The 63000 Series have a program sequence function for various load condition simulations. The minimum dwell time is 100μs. The following lists the applications for common programmed sequences:

  1. Battery discharge (NPC, electric car, and electric locomotive, etc.) simulating various dynamic load current waveforms.
  2. Switching power supply mixed load modulation.

Over Current & Over Power Testing (Available in May, 2018)
  • Set current orders to test overcurrent protections
  • Set power orders to test overpower protections
  • Automatic judge the test reslt as Pass or Fail
  • Capture the maximum power (Pmax) during testing
  • Verify the correctness of designed overcurrent and overpower without using an oscilloscope
  • Saves a lot of testing time
Graphical Operation Software (Available in July, 2018)

User friendly software controls all functions of the 63000 loads and is easy to understand and operate. The 63000 Series can be controlled via standard USB or optional GPIB/Ethernet interface for remote control and automated testing applications.
