DESCRIPTION:

The Delta Elektronika SM 120-50 is a 6000W programmable DC power supply designed for precision laboratory, industrial, and automated test applications requiring stable regulated DC output capability. The unit provides an output range of 0-120V and 0-50A with precision voltage and current regulation suitable for aerospace systems, telecommunications infrastructure, automotive testing, industrial automation, endurance testing, battery simulation, and production environments.

The SM 120-50 utilises high efficiency switch mode power conversion technology with efficiencies up to 89%, low ripple and noise characteristics, and excellent dynamic response performance for demanding dynamic load applications. The power supply supports both constant voltage and constant current operation and is engineered for continuous-duty industrial service.

Designed within the Delta Elektronika SM6000 series platform, the unit supports 0-5V analogue programming, voltage and current monitoring, remote sensing, interlock functionality, and automated instrumentation system integration capability. Master/slave parallel and series operation with voltage and current sharing are supported for higher power system configurations. Optional interface modules support Ethernet, RS232, IEEE488, CAN, PROFIBUS, isolated analogue programming, sequencer functionality, and high-speed programming operation.

The compact high-density design incorporates temperature-controlled forced-air cooling together with integrated overload, short-circuit, overvoltage, and thermal protection systems. EMC performance exceeds CE requirements with low emission and high immunity characteristics suitable for industrial environments. The unit supports bench-top and 19-inch rackmount deployment with three-phase 380V, 400V, or 415V AC input operation.
