Exploring Modular DC Electronic Load

Modular DC Electronic Load

Chroma 63600

State of the art design uses DSP technology to simulate non-linear loads using an unique CZ operation mode allowing realistic loading behavior

Power Rating

100W, 300W, 400W

Voltage Range

0~600V

Current Range

Up to 80A per module

Chroma’s 63600 Modular DC Electronic Load is designed for testing multi-output AC/DC power supplies, DC/DC converters, chargers, batteries, adapters, and power electronic components. They are excellent for use in 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 DC Electronic Load can draw its rated current under very low voltage (0.4V typical). This unique feature guarantees the best loading performance for modern Point-of-Load conditions and fuel cells.

10-in-1 provide 10 channels from five 100Wx2 channel loads within a 4U height mainframe to let users test various kind of power supplies such as Adapter/Charger/Monitor Power/ATX PSU/Server PSU/Battery/Fuel cell etc. In addition, the 4U height mainframe is able to install five 400W single channel modules in parallel for up to 2000W to test server power and fuel cells easily. The high power density design saves benchtop or rack space as well as total cost.


To comply with the trend of high power for PC power supplies, the new 400W module is able to satisfy the test requirements for +12V1 and +12V2. Only one 4U mainframe can have 300W(+3.3V), 300W(+5V), 400W(+12V1), 400W(+12V2) and 100W Dual(-12V/+5VSB) in plan for best load combinations to meet the up-to-date PC power supply test solutions.

63600-Low Voltage Operation

There are 28 low RDS_ON MOSFETs built into the 400W module that allow users loading up to 80A in 0.4V. When 5 of the 400W modules are paralleled for operation, up to 400A is available inside the chassis without the need for series connecting any bias power supply on the load internally or externally, so the noise measured was not affects by the bias power supply. All low voltage electrical specifications are measured by the Load terminal. It is suggested to use suitable Load Cable and twist pair the wiring to reduce the resistance and inductance.
