Delta MEP-500A Series - 500 W Medical Power Supply Now Available in Enclosed and Top Fan Configurations
More Integration Options for Compact Medical System Designs
Medical device designers working with high-power applications face a consistent set of constraints: strict safety isolation requirements, limited internal space, thermal management without compromising noise levels, and the need for certified, globally compliant power components.
Delta has expanded its MEP-500A Series medical power supply to address these challenges across a wider range of integration scenarios. Two new configurations join the existing open-frame model - an enclosed version and an enclosed version with integrated top fan - giving system designers three distinct form factors within a single, certified power supply family.
Three Form Factors, One Certified Platform
The MEP-500A Series now covers three mechanical configurations suited to different integration requirements:
- Open frame - for designs where the host enclosure provides mechanical protection and airflow management
- CRA (enclosed) - a protective enclosure that reduces the risk of accidental contact with internal components, streamlining system assembly and simplifying integration into end-equipment housings
- DRA (enclosed with top fan) - delivers the full 500 W output via an integrated low-noise fan, eliminating the need for external cooling arrangements while maintaining quiet operation appropriate for medical environments
The CRA enclosed model measures 3.5" × 5.5" × 1.5" in height, while the DRA with top fan measures 3.5" × 5.5" × 2.3" - both low-profile configurations designed to maximise usable space within compact medical equipment.
Performance Characteristics
Across all configurations, the MEP-500A Series delivers a consistent set of performance and electrical characteristics:
- Output power up to 500 W with fan cooling
- Output voltage options: 12 V, 18 V, 24 V, and 48 V
- 5 V / 2 A standby output for auxiliary power requirements
- Up to 95% efficiency
- Power density of 25.64 W/inch³ within a 3" × 5" footprint
- Operating temperature range of -40 °C to +85 °C
- 4 kV Electrical Fast Transient (EFT) immunity for stable signal processing and consistent image quality in electrically noisy environments
- Built-in remote on/off and remote sense voltage compensation
- Precision analogue voltage trimming
Medical Safety Certification
The MEP-500A Series is engineered to meet the safety standards required for medical equipment integration:
- 2× MOPP isolation for patient and operator protection
- Type BF classification for body-floating applications
- Certified to IEC/EN/UL standards across the medical, IT, and household sectors, supporting global market compliance
Target Applications
The combination of compact low-profile dimensions, high power density, low-noise fan options, and medical-grade certification makes the MEP-500A Series well suited for a range of medical system applications, including:
- Ultrasound imaging systems
- In vitro diagnostics (IVD) equipment
- Ventilators and respiratory support systems
- Operating tables and surgical lighting
- Medical imaging and signal processing platforms
