Product Information "Bidirectional programmable DC power supply and regenerative electronic load | IT-M3900C series"

ITECH IT-M3900C Series
Bidirectional DC Source and Electronic Load
Power: ±12 kW, Voltage: up to 1500 V, Current: up to 1020 A

Combined DC Power Supply & Electronic Load for Industrial Test Systems
The ITECH IT-M3900C Series is a bidirectional, programmable DC power supply with an integrated regenerative electronic load. The system replaces conventional combinations of DC power supplies and loads, thereby reducing the number of devices, required installation space, and overall integration effort.
Devices of the IT-M3900C Series provide consolidated test solutions with clearly defined functional scopes for complex testing and validation processes in development and production.

Planning Reliability for Development, Production, and ATE
In development departments, test fields, and automated test systems, reproducible results and stable test conditions are essential.
The IT-M3900C Series supports high-voltage testing, electrical safety testing, and compliance testing within a unified system.
Thanks to bidirectional energy flow control, test processes can be standardized and existing ATE environments can be efficiently expanded.

Bidirectional Operation for Load, Battery, and Energy Simulation
Seamless switching between source and sink operation enables the implementation of charge, discharge, and energy recovery scenarios without additional equipment. This makes the IT-M3900C Series suitable for battery simulation, load simulation, and testing of power electronics, energy storage systems, and electric drives. Test profiles can be flexibly adapted to different devices under test and development stages.

Scalable Test System with Focus on Operating Costs and Integration
Regenerative energy feedback supports energy-efficient test processes and reduces the effort required for cooling and power dissipation during operation. The compact design and standardized communication interfaces simplify integration into existing test benches and production lines.
As a result, users benefit from a long-term, scalable test solution with predictable investment and operating costs.
