EA-PSB 20000 Tripple

The electrification of the world is rapidly advancing, with industry and the public sector transitioning from fossil fuels to electrical energy, ideally sourced from renewables. Various requirements come together here: more power, more throughput, more flexibility.
As a new generation 3-channel bidirectional power supply the EA-PSB 20000 Triple allows synchronized testing to meet these requirements. It comes as a 3U and 4U version with a voltage range of up to 3 x 920 V and current up to 3 x 340 A. The product can operate independently or as part of a complete test system, including the rack in which it is housed.

The development of the EA-PSB 20000 Triple is not just a response to the market trends, but a necessary evolution to keep pace with the rapidly advancing fields of electrification and testing.

Key Features

• 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
