Delta Elektronika designs and manufactures laboratory and programmable DC power supplies, and Powerbox distributes the complete range in Australia with application engineering support. This Dutch manufacturer is renowned for low-noise, high-efficiency power conversion, building bidirectional DC supplies from 800W to 15kW per unit and expanding into multi-unit systems that deliver 150kW and beyond.

The SM series sits at the core of the range, offering both source and sink operation in a single unit. Regenerative Power Recovery returns energy to the grid at up to 95% efficiency, cutting running costs and heat load in continuous test setups. Auto-ranging outputs simplify configuration across wide voltage and current windows, and full programming via Ethernet and serial interfaces supports automated test sequences, data logging and remote monitoring across a lab or production floor.

These power supplies are trusted across research and development, battery testing, solar inverter testing, EV simulation and aerospace applications throughout Australia, wherever engineers need clean, precisely controllable DC power at high continuous ratings. Powerbox's application engineering team supports specification, configuration and system design for single-unit and multi-unit installations, helping match the right model in the Delta Elektronika range to demanding test and production environments, from single bench supplies through to multi-cabinet test systems.
