PSB-20000 Triple-Series

The bidirectional DC laboratory power supplies of the PSB 20000 Triple series from EA Elektro-Automatik are two-quadrant devices that can perform both the function of a power supply (source) and an electronic load (sink). In sink operation, the device operates regeneratively and feeds the energy back into the local power grid with an efficiency of up to 96%.
- Three-channel bidirectional operation: Enables parallel testing of multiple components (motors, inverters, chargers) with just one device.
- Space-saving: Reduces rack space requirements by more than 50% compared to single-channel devices.
- Cost-efficient: Lowers investment and operating costs through fewer devices and high energy recovery (up to >96%).
- Faster development cycles: Shortens validation and integration times, accelerating product development.
- Flexible & powerful: High power in a compact design, ideal for automotive and renewable energy applications.
