19" rack power supply EA-PSB

DCsingle-outputregulated

Overview
The EA-PSB (EA Elektro-Automatik) EA 20000 and 10000 series are bidirectional regenerative DC power supplies designed for industrial test and validation applications. They recover energy back to the AC mains with >96% efficiency, offer true autoranging for maximum usable power across wide voltage/current combinations, and include integrated function generator and test routines for battery, fuel-cell and PV simulation.

Key Capabilities

• Regenerative (bidirectional) operation: source and sink power, feed recovered energy back to the facility mains/grid.
• Autoranging: maintains rated power over broad voltage/current ranges (down to ~33% of rated max).
• Built-in AFG with arbitrary waveform and sequencing for complex test signals.
• Included simulation/test modes: battery test, fuel cell simulation, PV array simulation with MPP tracking, inverter efficiency support.
• Multiple interfaces: USB, Ethernet standard; optional field-installable AnyBus modules (ProfiNet, CANopen, Modbus‑TCP, DeviceNet, EtherCAT, RS‑232, CAN FD, etc.).

20000 Series Highlights
The 20000 Series provides three independent, fully isolated channels, ~1 ms response/communication capability and integrated safety sense to compensate cable drops. Channels include AFG and test routines; units can be paralleled for very high power and support voltages up to 2000 V DC depending on model.

PSB 10000 Series — Technical summary

• Power: from 1.5 kW up to 30 kW (series/model dependent)
• Voltages: 0–60 V up to 0–2000 V (model dependent)
• Current: 0–6 A up to 0–1000 A (model dependent)
• Highlights: bidirectional, autoranging, Ethernet/USB/analog interfaces, optional plug-and-play AnyBus modules

PSB 20000 Triple Series — Technical summary

• Power per channel: 0–5 kW to 0–10 kW (series dependent)
• Voltage per channel: 0–60 V up to 0–920 V (model dependent)
• Current per channel: 0–20 A up to 0–340 A (model dependent)
• Highlights: 3 independent isolated bidirectional channels, 1 ms communication speed, USB/EtherCAT/CAN FD interfaces

Quick Product Capacity Summary

• Power: up to 30 kW (single-channel models) — rack/industrial variants and parallel systems enable much higher aggregate power
• Voltage: up to 2000 V DC (model dependent)
• Current: up to 1000 A per channel (model dependent)

Models (series-level selection and ranges)

• EA-PSB 10000 4U — 0–30 kW; voltages 0–60 V up to 0–2000 V; currents up to 1000 A per channel; 1 channel
• EA-PSB 10000 3U — 0–5 / 0–10 / 0–15 kW; voltages up to 2000 V; currents up to ~170 A per channel; 1 channel
• EA-PSB 10000 2U — 0–1.5 / 0–3 kW; voltages up to 1500 V; 1 channel
• EA-PSB 20000 Triple 3U / 4U — per-channel 0–5 kW / 0–10 kW; 3 independent channels; voltages up to 920 V per channel

Built-in Function Generator and Test Features
The integrated AFG supports standard and arbitrary waveforms with sequencing and scales across parallel supplies. Typical uses include solar cell (VOC/ISC/MPP) simulation, inverter efficiency testing (standards guidance), and automotive tests (LV123/LV124/LV148).

Regeneration (energy recovery)
EA regenerative supplies can recover up to ~96% of absorbed energy and feed it back into the facility mains or public grid (depending on installation). This reduces cooling/HVAC requirements and improves facility energy efficiency.

Control & communications
Standard interfaces include USB and Ethernet; optional AnyBus field-installable modules add ProfiNet, CANopen, Modbus‑TCP, DeviceNet, EtherCAT, RS‑232, CAN FD and other industrial protocols to suit manufacturing control systems.

Industrial series and scalability
Industrial EA-PSB variants are available in 2U/3U/4U/6U and 19" rack formats for high power density. Rack systems and parallel configurations enable multi‑hundred kW to multi‑MW installations (example: up to 3.84 MW in specific parallel rack configurations).
