LMF1000 AC-DC converters introduce new features for today’s industrial applications

26 October 2022


AC-DC converters by Mornsun are characterised by features designed to support various industrial applications in a compact, cost-efficient form factor. The LMF1000 series is available from Relec Electronics.

The latest addition to the AC-DC converter portfolio from Relec Electronics is the Mornsun LMF1000 series. The high power density, enclosed power supplies range from 15W to 1000W and are ideal for industrial applications. 

The manufacturer has introduced new features, which include 5V 2A auxiliary supply, fully automatic variable fan speed control, I2C communication, boost mode power and parallel operation.

All models in the series feature output short-circuit, over-voltage, over-current and over-temperature protection.

An internal ORing can be used to implement higher power and redundant (N+1) systems. A single wire current share facilities enables up to four LMF1000 AC-DC converters to be wired in parallel.

The compact modules operate at up to 94% efficiency and have a superior power density of 17.22W/inch3. The compact dimensions of just 190 x 127 x 40.5mm mean they are suitable for 1U rack-based and standard cabinet projects.

The AC-DC converters can be used worldwide, having approval to EN/UKCA/UL62368-1 (5000m operation). They are also certified to EN60601-1-2 for medical applications with 4000Vac isolation from input to output (Class I use).

All models in the series have near unity power factor correction (typically 0.99) and are therefore compliant with EN61000-3-2 class D operation.

MTBF is 250,000 hours and above and the power supplies meet 5g vibration specifications.

Other features include analogue control features, including remote on/off, DC OK, sense lines and current sharing. An I2C digital bus allows users to monitor performance with readings of voltage and current on both main and auxiliary outputs and status readings for protection circuits and individual circuit blocks.

The LMF1000 series by Mornsun is available on short lead times. All models are covered by a five year warranty.
