N35100
Bidirectional Low-Voltage DC
Bidirectional low-voltage DC power supply with regenerative load for battery and automotive testing.
The N35100 series is a compact bidirectional DC power supply with integrated regenerative load capability, designed for modern R&D, laboratory, and production test environments. The unit can both source and absorb power, feeding recovered energy back to the grid to reduce energy consumption and cooling requirements. A single unit provides up to 7.5 kW output power, voltage ranges up to 40 / 80 V, and currents up to ±300 A, delivering high power density in only 1U height. For higher power requirements, the series supports master-slave parallel operation, allowing multiple units to be combined for scalable total system power. Operating modes include CC, CV, CR, and CP, with seamless transition between source and load operation. Features such as battery simulation, PV simulation, sequence testing, and charge/discharge profiles enable realistic and automated testing workflows. LAN, RS232, RS485, and CAN interfaces ensure easy integration into automated test benches and ATE systems. Typical applications include battery testing, automotive electronics validation, DC/DC converter testing, photovoltaic simulation, fuel cell testing, and R&D environments, where bidirectional energy flow and scalable power are required.

Bidirectional Programmable DC Power Supply Series N35100: Maximum Power Density and Highly Efficient Energy Regeneration in 1U
In modern industrial test environments, the strategic integration of bidirectional systems is a key factor for time and cost efficiency. The N35100 series combines a highly precise DC power supply and a regenerative electronic load in one compact housing.
Thanks to its dual-quadrant functionality, the system can both supply energy and feed it back into the local power grid with high efficiency. This significantly reduces both thermal load and operating costs.
Key Advantages for R&D and Production
The efficiency of modern test benches is largely determined by the form factor and energy balance of the components used. This system offers a powerful combination of compact size, control quality and efficiency.
Typical Applications
The N35100 series is designed for a wide range of industrial test tasks where bidirectional energy flow, high dynamics and precise control are required.
The bidirectional source can both deliver and absorb energy, enabling realistic charge and discharge cycles for lithium-ion, lead-acid and supercapacitor testing.
The device simulates the electrical behavior of a battery and enables the development and validation of battery management systems without using a real battery.
Stable voltage and current operation combined with fast dynamics enables testing of efficiency, control behavior and load transitions of DC-DC converters.
The source simulates a battery or DC link and can operate as a load at the same time to test chargers under realistic conditions.
PV curve simulation makes it possible to emulate real solar conditions in order to test MPPT control and efficiency.
Simulation of charge and discharge processes in large battery storage systems for verification of control units and power electronics.
Simulation of mains or battery conditions to test transfer behavior, efficiency and stability of UPS systems.
Dynamic current and voltage profiles enable testing of power electronics for motor control applications.
Integration via LAN, CAN or RS interfaces enables automated testing of assemblies and components in production lines.
Simulation of electrical load and regenerative energy flow for characterization of fuel cells and their power electronics.
Stable power supply and programmable load profiles enable testing of power supplies used in telecom and server hardware.
Programmable voltage profiles and high power density allow realistic testing of airborne electronics and drive systems.
Functional and System Description
The system is based on a modern bidirectional control concept for stable and reproducible test processes. Source and sink functions are combined in such a way that the energy flow between the DUT and the supply grid can be controlled bidirectionally.
Technical Key Data
Variants and Configuration Options
Version with half 19-inch width of 214 mm for compact laboratory and test cabinet solutions.
Version with full 19-inch width of 428 mm for higher power while maintaining a compact 1U design.
Integration and Automation
For integration into automated production lines and complex test bench systems, the solution offers a wide range of interfaces. Standard interfaces such as LAN, RS232, RS485 and CAN enable easy integration into existing architectures.
Added Value for Industrial Users
Beyond the technical specifications, the system offers significant added value in terms of total operating costs. High regenerative efficiency not only reduces energy costs, but also significantly lowers heat generation in the test field.
This reduces strain on laboratory infrastructure, supports the service life of installed electronics and improves overall operational safety. Users also benefit from local support and fast response times through the competence center in Germany.
