Technical Description of Eltek Flatpack 48/1500 Rectifier
The Eltek Flatpack 48/1500Rectifier uses soft-switching technology with a high switching frequency to achieve a high power density while minimizing overall volume and weight.
- Operation Modes: It can function as a standalone charger or as part of a larger power rack system typically controlled by a Flatpack MCU (Monitoring & Control Unit).
- Parallel Capability: When connected in parallel, modules provide active current sharing even without a separate control unit.
- Thermal Control: The unit is fan-cooled with two temperature-regulated brushless fans that provide front-to-back airflow.
- Visual Indicators: Features a front-panel LED bargraph (10 green LEDs) that indicates output current from 0–100%, along with Red and Green LEDs for status and failure alerts.
