Cabinet power supply I-TS-3840

DCthree-phaseIP54

Overview
The I-TS-3840 is a single-channel bidirectional DC source/sink designed for high-dynamic tests in automotive, hydrogen and laboratory environments. The unit is based on standardized configurations with selectable options so that no additional engineering effort is required after order placement.

Product concept
High-dynamic DC power system with continuous, seamless transition between source and sink operation. Suitable for battery testing, battery emulation and load applications where fast current response and precise control are required.

Standard features

• Single-channel I-TS-3840 configuration with extensive factory equipment
• Main switch (load-break switch with fuses on AC input; lockable in off position)
• Safety control to Performance Level d (PLd) per ISO 13849-1 / EN 60204-1
• Touch display and analog voltmeter on the cabinet door
• Switchable tester / simulator functions
• DC contactors with increased short-time current capacity
• Dedicated terminals for DC voltage measurement (0.1% accuracy with sense lines)
• External terminals for emergency stop and stop
• Modbus TCP/IP, CAN bus (100 Hz, dbc file), VNC via Ethernet

Typical applications

• Battery charge and discharge testing
• Battery simulation / emulation
• Load for fuel cells
• Test power supply for contactors, fuses and circuit breakers
• DC motor and drivetrain testing
• Charging station testing
