The MPL MRS-50-12-U-C is a 50.4W enclosed metal power supply providing a regulated 12V DC output at up to 4.2A. Its universal AC input accepts 85–264VAC or 120–373VDC, making it compatible with mains supplies worldwide without adjustment.

The low-profile 1U metal case (AL1100 and SGCC materials) measures 9.9 x 8.2 x 3.0cm — the most compact in the MRS range. An adjustable output voltage from 10.2V to 13.8V (minimum) allows fine-tuning for the connected load. Built-in protections cover over-current, short circuit, over-voltage, and over-temperature conditions.

Key Features

• 12V DC output at 4.2A maximum — 50.4W total output power
• Universal AC input: 85–264VAC / 120–373VDC full range
• Adjustable output voltage range (MIN.): 10.2V to 13.8V
• Low no-load power consumption: less than 0.3W
• Built-in protections: over-current, short circuit, over-voltage, over-temperature
• LED power-on indicator
• Low 1U profile metal enclosure (AL1100, SGCC)

Product Benefits

• Universal input eliminates the need for a voltage selector — works on any mains supply from 85 to 264VAC
• No-load consumption below 0.3W is the lowest in the MRS range, minimising idle energy draw
• Adjustable output allows compensation for cable drop or fine-tuning for sensitive LED loads
• Compact 9.9 x 8.2 x 3.0cm case fits in small enclosures where larger supplies would not
• Wide operating temperature range of -30°C to +70°C allows use in unheated or outdoor enclosures
