ML50.111

PULS ML50.111 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 features a plug connector NEC Class 2 optimized for parallel use, including a DC-OK relay contact output. The unit has a rated current of 2.1A at 24Vdc and utilizes screw-clamp connections for secure installation. 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 ML50.111 is housed in a PC / ABS blend, measuring 45mm in width, 75mm in height, and 91mm in depth. It is compatible with single-phase (1AC) or DC networks, has a rated power of 50W, and provides an adjustable output voltage from 24Vdc to 28Vdc with a 400mV turn-ON overshoot. Protection is ensured by an NTC (input inrush current limiter), and the unit boasts an efficiency of 0.885 at 230Vac input. Maximum current consumption is 17A at 120Vac input and 35A peak at 230Vac input, with power dissipation/losses at 6.8W and a ripple of 50mVpp across 20Hz to 20MHz at 50Ω. The output stage capacitance is 1600µF.
