Rack-mount power supply EA series

DCregulatedvariable-output

Overview
Configure 3U, 4U and 6U devices into 42U, 38U, 24U and 15U racks. Combine EA-10000 and EA-10000 Industrial series bidirectional power supplies, programmable power supplies, or regenerative loads. Parallel connection scales system power up to 3.84 MW (64 devices across 13 racks); a single 42U rack can host five 60 kW units (300 kW).

Safety & Protection

• Integrated safety system
  Prepared for connection to 3-phase mains (typ. 400 V). Includes fast stop (emergency stop) and rear-door contact switches.
• Central safety relay
  Monitors safety chain and can disconnect redundant AC contactors when required.
• Fuse protection
  All devices and cabling protected by dedicated fuses.

Options

• Water Cooling
  Preinstalled water distribution for low-noise, high-density environments.
• NS Protection (Network & Supply)
  Monitors AC grid to prevent islanding and shuts down the rack on mains faults.
• Insulation Monitor
  Detects insulation faults between DC output and earth and triggers system shutdown if needed.
• DC Contactor
  Provides safe disconnection between the power system and the DUT; integrated into the fast-stop chain.
• DC Copper Bar (Busbar)
  Facilitates paralleling of multiple devices to boost rack output performance.
• Ethernet Switch
  Optional 24-port switch for consolidated multi-channel control via a single Ethernet interface.
• Signal Lamp
  Provides clear visual system status indication.

Rack Configurations & Use Cases

• 15U cabinet — up to 60 kW: compact footprint for labs or entry-level setups.
• 24U cabinet — up to 180 kW: balanced size for mid-range applications and scalability.
• 42U cabinet — up to 300 kW: high power density for industrial or R&D environments; scalable to multi-rack systems.
• Multi-rack systems — up to 3.84 MW (13 racks): consolidated emergency-stop chain and minimal overall footprint for large installations.

Software

• EA Power Control — Windows software package to manage, control and program EA devices from a PC. Provides HMI-equivalent control and advanced simulation/testing functions.
