SL1800A Series Scienlab Regenerative DC Emulator

Data Sheets

Systems With an Output Power Range of 100 kW  up to 330 kW


Highly efficient test of high-power applications with a small footprint.


The Keysight’s Scienlab Regenerative DC Emulator - High-Power Series with new silicon carbide (SiC) technology is a highly efficient system based on state-of-the-art technology. It allows the user to realistically emulate the electric vehicle battery in charging test applications, such as high-power DC fast charging, when paired with the SL1047A Scienlab Charging Discovery System – High-Power Series.

The switching frequency of silicon carbide transistors is greater than 10X when compared to IGBTs. This results in a significantly higher efficiency reducing costs by reducing heat dissipation (lower cooling costs), and lower energy consumption (lower electricity bill). Higher switching frequencies also enable the use of smaller components resulting in a system with a smaller footprint requiring less of your valuable floor space.




• Smaller footprint compared to systems with similar power

• 1.5 MW power due to parallelization

• Up to 1500 VDC for emulating high-voltage batteries

• Based on new high-voltage silicon carbide (HV-SiC) technology

• Highly efficient with a recovery capability of up to 96%

• Reduced energy consumption and cooling water




In the following, a distinction is made in the technical data between specifications and supplemental characteristics. Unless otherwise noted, specifications are warranted over the ambient temperature range of 5 to 40 °C after a 30-minute warm-up period.

[1] Parallel connection of several systems possible to achieve higher currents. If two or more systems are connected in parallel, all output stages are supplied equally regardless of the actual current class of the individual systems. In this case, the cross-sections of the DC cables must be designed accordingly. Achieve up to 1.62 MW (3600 A) with a parallel connection of up to six systems e.g., by connecting the individual DC cables to a remote power terminal (RPT) or a power switch terminal (PST).
