Compact DIN-Rail Supply for 48V Systems

The PULS ML50.105 is a single-phase switching power supply built for DIN-rail mounting in control cabinets. It accepts 100 to 240V AC or 110V DC input and delivers an adjustable 48 to 56V DC output at 50W. A green LED provides immediate status indication.

Input Range and Output Constraints

The unit operates from 50 to 60Hz mains and holds output for 40msec during interruptions. Output noise is specified at 200mV, and the supply is NEC Class 2 listed for limited-power circuits. It is rated IP20, so it requires an enclosure for finger-safe protection.

50W Capacity with Industrial Temperature Range

Continuous output current is 1.05A, with the output voltage adjustable between 48V and 56V. The supply runs from -10°C to 70°C inside a 75mm high, 45mm wide, 91mm deep plastic case. Designs needing more than 50W or a higher current rating will require a larger unit.

Questions about this item

How do I decide between the 48V and 56V output range?

The unit delivers a continuous 48 to 56V DC window; set the trim within that span to match the load's nominal voltage and the 1.05A limit.

What does the 50W rating mean once the supply is mounted on a DIN rail?

At full load the converter provides 50W with 200mV output noise and 40ms hold-up time across the -10 to 70°C operating range.

Which AC input standard does the 100-240V 50-60Hz front end follow?

The single-phase input accepts 100 to 240V AC at 50 to 60Hz and 110V DC, meeting NEC Class 2 listing for the 50W output.
