The Delta Electronics MEB-750A series are enclosed AC/DC power supplies designed for medical and industrial applications requiring high-density, high-power output with a dedicated 5 V / 2 A standby rail. Available in 12 Vdc, 24 Vdc and 48 Vdc output configurations, the series delivers up to 750 W continuous power (700 W for 12 V models) and up to 1200 W peak on the 48 V model — all within a compact 177.8 × 101.6 × 40 mm (7" × 4" × 1.575") enclosed package.

Two inlet options are available: C14 inlet (B models, 85 Vac fixed input) and American barrier strip terminal (T models, 90–264 Vac universal input). T models maintain full-rated output across the full universal input range.

The MEB-750A series features 2 × MOPP galvanic isolation and is rated for Type BF medical product applications. Additional features include conformal coating, current sharing for parallel operation, remote on/off control with power good signal output, remote sense compensation of up to 500 mV, voltage trimming, and IEC 60601-1-2 4th Edition immunity compliance. The series meets Class B conducted and radiated EMI requirements and includes a built-in cooling fan.

FAQs
The MEB-750A is available in 12Vdc, 24Vdc, and 48Vdc output models at 750W total output power — for example, the MEB-750A24T delivers 24Vdc at 31.25A. All models accept a universal 90–264Vac input and achieve approximately 92% efficiency.
The MEB-750A is certified to IEC 60601-1 and UL 60601-1 (medical electrical equipment safety), qualifying it for integration into Class I medical devices and equipment used in patient care environments. It also holds IEC 62368-1 for dual-use medical/industrial applications.
The MEB-750A (750W) is the mid-range model positioned above the MEB-500A (504W) and below the MEB-1K2A (1200W) and MEB-1K5A (1500W). All share the same internal panel-mount enclosed format with intelligent fan speed control and PMBus interface. Choose the MEB-750A when your equipment's power budget falls between 500W and 1000W.
Universal 90–264Vac single-phase input, covering Australian and New Zealand mains (230Vac) and international 115Vac without manual switching. The wide input range supports global equipment designs and Australian/NZ market deployments without modification.
The MEB-750A supports active current sharing for parallel operation (N+1 redundancy or combined power scaling), PMBus v1.3 digital interface for voltage adjustment and monitoring, and analogue ±10% voltage adjustment. Intelligent fan speed control minimises audible noise relative to load conditions.
The MEB-750A provides 2×MOPP (Means of Patient Protection) isolation between input and output, meeting the IEC60601-1 third edition requirements for devices operating in direct patient care environments. This leakage current level is mandatory for applied parts and patient-connected equipment in Australian medical device compliance.
