ML50.101

PULS ML50.101 is a power supply unit (PSU) / converter designed for AC/DC applications with DIN rail mounting. It operates within an ambient air temperature range of -10 to +70°C and is optimized for parallel use with a DC-OK relay contact output. This unit has a rated current of 2.1A at 24Vdc and utilizes spring-clamp connections for connectivity. It supports a wide supply voltage range from 85Vac to 264Vac (with specific nominal values across 100Vac to 240Vac; 47-63Hz), including a 65Vac turn-ON voltage and a 55Vac shutdown voltage, as well as a DC supply voltage range from 88Vdc to 375Vdc. The ML50.101 features a PC / ABS blend housing, is compatible with single-phase (1AC) or DC networks, and has dimensions of W45mm x H75mm x D91mm. It offers a rated power of 50W and an adjustable output voltage range from 24Vdc to 28Vdc. Protection functions include an NTC for input inrush current limiting. The efficiency is rated at 0.885 with a 230Vac input, and it has a maximum current consumption of 17A inrush at 120Vac input and 35A peak max. inrush at 230Vac input. The unit exhibits a 32ms start-up delay, a rise time of 33-48ms under nominal input with a constant full current load and 0mF load capacitance, and a 45-60ms rise time with 2mF load capacitance. Power dissipation/losses are calculated at 6.8W, with a ripple of 50mVpp across 20Hz to 20MHz at 50Ω, and an output stage capacitance of 1600μF.
