Description

The Delta Elektronika SM 3540-D is a high-power regulated DC power supply designed for demanding laboratory, industrial and automated testing applications. It provides a continuously adjustable output from 0–35 V DC with current up to 40 A, delivering a maximum output power of approximately 1,400 W. The SM 3540-D supports constant-voltage and constant-current operation, enabling stable operation with different electronic loads. It also provides analogue voltage and current programming, remote sensing and protection against overload, short-circuit and excessive temperature conditions. Its natural-convection cooling system operates without a cooling fan, helping reduce acoustic noise and maintenance requirements. The power supply is suitable for testing RF amplifiers, communication equipment, automotive electronics, motors, batteries, circuit assemblies and other high-current devices. Its high output capability, reliable regulation and remote-control features make it useful in research laboratories, manufacturing facilities, production testing, equipment servicing and industrial quality-control environments.
