MEANWELL ML100.200 Product Description

Overview

MEANWELL ML100.200 requires a maker note: the public datasheet and PULS product record identify ML100.200 as a PULS MiniLine MLY series DIN-rail power supply, not as a MEAN WELL product. The unit supplies 24 to 28 V DC for 380 to 480 V AC industrial control systems. If the supplied label says MEANWELL, verify the rating plate and packaging because ML100.200 appears in public records under PULS MiniLine rather than Mean Well catalogue references.

Features

The ML100.200 DIN-rail power supply accepts AC 380 to 480 V, tolerance ±15 percent, and uses a two-phase or three-phase high-voltage input arrangement according to the PULS record. It does not require a neutral wire. The DC output nominal voltage is 24 V DC, adjustable over 24 to 28 V. Output current is 4.2 A at 24 V and 3.6 A at 28 V, with output power 100 W.

Input power factor is listed as 0.6. Inrush current limitation is NTC, with input inrush current 30 A / 36 A. Recommended external input fuse is B-10 A or C-6 A. Output ripple and noise voltage maximum is 50 mVpp. Derating is 2.5 W per degree Celsius above +60 degrees Celsius.

The supply mounts on a DIN rail and uses spring-clamp quick-connect terminals. Dimensions are width 73 mm, height 75 mm and depth 103 mm, with unit weight 360 g excluding packaging. Typical efficiency is 89.5 percent, typical power loss 11.7 W, and MTBF according to SN 29500 at 40 degrees Celsius is 1,594,000 hours.

Principle

The DIN-rail power supply converts the high-voltage AC control supply into regulated DC 24 V for PLCs, sensors, relays, contactor coils, valve solenoids, indicator circuits, I/O modules, communication devices and other 24 V DC control loads. The output adjustment range allows compensation for voltage drop in long panel or field wiring. Spring-clamp terminals provide quick wiring and vibration-resistant connections in industrial panels.

Replacement should verify the actual manufacturer and model on the rating plate, AC input phase arrangement, nominal output voltage, adjustable range, rated current, power capacity, fuse rating, terminal polarity, DIN rail space, output load current, backup or decoupling module, and whether the original supply used load sharing or parallel operation. Power supplies may retain dangerous DC bus or output voltage after disconnection; installation and servicing should follow the manufacturer manual, lockout, tagout and qualified-personnel requirements.

Applications

ML100.200 is used in existing 380 to 480 V AC industrial control panels, PLC cabinets, motor control centers, machine tools, packaging lines, conveyors, process skids, pumping stations, marine auxiliary panels and automation systems needing regulated 24 V DC control power. In legacy installations, it serves as a replacement DIN-rail power supply spare when the input voltage, output voltage, current rating, terminals, mounting and load configuration match the original unit.
