63600 Series Modular DC Electronic Load

63600 Series Modular DC Electronic Load

Chroma's 63600 Series DC Electronic Loads are designed for testing multi-output AC/DC power supplies, DC/DC converters, chargers, batteries, adapters, and power electronic components. Excellent for research, development, production, and incoming inspection applications. The 63600's state of the art design uses DSP technology to simulate non-linear loads using an unique CZ operation mode allowing realistic loading behavior. The 63600 series can draw its full rated current to almost zero volts. This unique feature guarantees the best loading performance for fuel cells and modern Point-of-Load devices.

6310/A Series Modular DC Electronic Load

6310/A Series Modular DC Electronic Load

PLEASE NOTE: The 6310 has been renamed the 6310/A Series due to the addition of 6 New Features.

  • New Features - with no additional cost
  • Max Power: 200W, 100W×2(Dual), 30W & 250W, 300W, 600W, 1200W
  • Wide range 0~500V operating voltage
  • Up to 8 channels in one mainframe, fit for testing multiple output SMPS
  • Parallel load modules up to 1200W for high current and power application

New Features Added:

  • Constant Power (CP) Mode: Constant Power mode is ideal for battery capacity testing, battery life cycle testing, as well as output power versus efficiency curve testing.
  • Average Measurement: Due to certain UUTs having a low frequency output voltage ripple causing 6310 series measurements to fluctuate with the ripple, the 6310A series has included a new average measurement function to allow for a stable measurement from the DC Load.
  • Over Current Protection (OCP) and Over Power Protection (OPP) Test: The 6310A provides OCP and OPP testing with a dwell time setting to allow for OCP and OPP slew rate control, ideal for different OCP/OPP testing conditions.
  • Timing Measurement: Timing measurements for Battery and supercapacitor discharge time measurements.
  • Digital I/O Control: The digital I/O control is ideal for the automated testing environment. The 6310A can be controlled through the digital I/O and the load status obtained from the digital I/O signal.
  • USB Interface: Due to the wide spread use of the USB interface, 6310A provides the USB and GPIB interface as an optional interface, while RS-232 comes as standard.
