Key Features

• High-Voltage Bidirectional Operation: Functions as a programmable DC power supply (source) and regenerative electronic load (sink) with a wide output range of 0-750 V and 0-240 A, achieving up to 96.5% energy recovery efficiency for reduced operational costs.
• Constant Power Autoranging: Delivers a full 60 kW across its wide voltage and current ranges, providing a flexible testing platform that can replace multiple fixed-range power supplies.
• Precision Control & Measurement: Digital regulation in CV, CC, CP, and CR modes with fast crossover. High-resolution 16-bit architecture ensures accurate setpoints and measurements (voltage ≤0.05% FS, current ≤0.1% FS).
• Scalable High-Power Systems: Integrated Master-Slave and Share-Bus enable seamless parallel operation of up to 64 units from the 10000 series, creating synchronized systems with power up to 3840 kW that function as a single instrument.
• Extensive Connectivity: Standard isolated interfaces include USB, Ethernet, and analog (DB15). Optional plug-in cards provide industrial communication like CAN, CANopen, Profibus, EtherCAT, Profinet, and Modbus for easy integration into automated test environments.
• Robust Safety & Standards Compliance: Designed to meet EN/IEC/UL/CSA 61010-1 safety standards. Includes overvoltage (OVP), overcurrent (OCP), overpower (OPP), and overtemperature (OT) protections. Complies with relevant EMC directives for reliable operation in industrial settings.
• Universal Three-Phase Input: Wide AC input range of 380-480 VAC ±10%, 3-phase, 45-65 Hz, with active Power Factor Correction (typical 0.99), ensuring compatibility with global power grids.
• Dedicated Application Suites: Optimized for high-voltage Battery Test Systems, Fuel Cell Test Systems, Solar Array Simulators (PV Inverter Test), On-Board Charger (OBC) Test Systems, Battery Simulation, and Battery Recycling Test Systems.
