A future-proof and flexible solution

For demanding industries
across all sectors

The EA-PSB 20000 Triple was designed to achieve what other devices have previously failed to do. It is therefore the only solution for running a wide range of tests in an efficient, cost-saving and reliable way at high speed - and all in just one device.

Two examples illustrate the immense potential of the EA-PSB 20000 Triple.

PV inverters

Conventional solutions reach their limits with PV inverters, as two panel inputs and a third for the battery output have to be tested. With its three channels, the EA-PSB 20000 Triple fulfills this requirement. The built-in software can also recognize the MPP (Maximum power point) tracking to determine the efficiency of the PV inverter.

Automotive Testing

Electrification of vehicles introduces new electrical components, making design and testing critical. With higher voltages and advanced energy systems, testing demands now cover all electrical subsystems. EA Elektro-Automatik's triple-channel bidirectional DC power supplies offer flexible, efficient solutions for testing modern EV components.

Built-in interfaces

• With three independent channels, customers can conduct parallel testing on different components or subsystems, such as motors, inverters, and on-board chargers, within the same test setup. This reduces the time needed to validate each component individually.
• The occupation of rack space is reduced by more than 50% when using triple devices instead of single output devices.
• By enabling more efficient testing and reducing the time required for validation and integration, a triplechannel power supply helps customers accelerate their development process. This is particularly important in fast-moving industries like automotive and renewable energy, where being first to market can be a significant competitive advantage.
• Operational expenses are significantly lower due to high energy recovery (up to greater than 96%) when used in bidirectional mode. Both operational and HVAC energy cost savings are realized.

• Worldwide Input Voltage: 208 V - 480 V, +/- 10%, 3ph AC
• Active Power Factor Correction, typical 0.99
• Very high efficiency of over 96% in regenerative with energy recovery back to the grid
• Voltages from 0 - 60 V up to 0 - 920 V
• High performance with up to 10 kW per channel
• Currents from 0 - 20 A up to 0 - 340 A per channel
• 3 Independent, fully isolated and bidirectional DC output/input stages, with autoranging
• Galvanically isolated Share-Bus for parallel operation
• 3 Built-in high speed control interfaces with 1 ms communication speed
