MEAN WELL MP series: Isolated dual-output module - MD-100U

Description

MD-100U — Isolated dual-output module

MD-100U is a MEAN WELL MP one-slot isolated dual-output module rated 100 W in total. This listing highlights CH2: 5 V DC, 8 A rated current and a 0–10 A specified current range. The module still contains both outputs; their combined load must remain within the shared power rating. It installs in a compatible MP PFC system and provides remote inhibit and separate channel adjustment.

Model and electrical specifications

Model and configuration MD-100U; MEAN WELL MP series. MD-100 (100 W family designation); one-slot isolated dual-output module; both channels belong to this one complete module. Main catalog revision: 2024-09-04.
Selected output channel CH2
Selected channel rating CH2: 5 V DC; rated current 8 A; current range 0–10 A. This is the selected channel of a dual-output module, not a separate single-output model.
Complete dual-output ratings CH1: 24 V DC, 2.5 A rated, current range 0.5–3 A. CH2: 5 V DC, 8 A rated, current range 0–10 A. Combined rated output power: 100 W, shared by both outputs.
Channel adjustment and total power CH1: 22.8–26.4 V; CH2: 4.75–5.5 V. When voltage is raised, derate current to keep both outputs within the total rated power.
Ripple and noise CH1: 200 mVp-p maximum; CH2: 100 mVp-p maximum. Measured at 20 MHz bandwidth using a 12-inch twisted pair terminated with 0.1 µF and 47 µF capacitors in parallel.
Channel voltage tolerance CH1 ±3.0%; CH2 ±3.0%. Includes setup tolerance, line regulation and load regulation.
Line and load regulation Each channel: line ±1.0%; load ±2.0%.
Setup, rise and hold-up time 1500 ms setup, 50 ms rise and 20 ms hold-up at full load. System Note 1 gives 20 ms typical hold-up for its specified module combinations; use the assembled configuration when assessing system hold-up.
Input and system boundary This output module operates in an MP front-end system; it is not a standalone AC-input power supply. The PFC front end accepts 85–264 V AC / 120–370 V DC, 47–63 Hz and provides active PFC. Choose the actual front end and module mix to satisfy all system and output limits.
MP platform feature scope The MP platform supports configurable output combinations. Its PFC front end provides active PFC compliant with EN61000-3-2 and a 12 V / 0.1 A auxiliary supply only for remote ON/OFF control. MS single-output modules provide constant-current limiting and remote sense; individual output modules provide remote inhibit. Parallel operation is available for MS-210, MS-300 and MS-360; margin control is available only for MS-210 and MS-360. These are family-specific system capabilities, not functions attributed to every installed module.

Control and protection

Module remote inhibit +RC/−RC: 0–0.8 V or open = module ON; 4–12 V = module OFF. This controls the individual module. The PFC system CN4 instead requires a low level or short for ON and is OFF when open.
Overload protection 105–150% of rated output power; output shutdown, re-power on to recover.
Overvoltage protection CH1: 26.5–34 V; CH2: 5.6–7.2 V. Output shutdown; re-power on to recover.
System protection and cooling boundary The MP system lists short-circuit protection and uses a built-in DC fan with fan alarm. System overtemperature shuts down outputs with automatic recovery after cooling; fan malfunction also shuts down outputs. These are assembled-system functions, not a separate fan or auxiliary supply built into this output module.

Operating environment and system derating

System operating environment MP assembled-system working temperature: −20°C to +70°C with derating; humidity 20–90% RH, non-condensing. Storage: −40°C to +85°C, 10–95% RH, non-condensing.
Ambient-temperature power curve For horizontal installation, the curve permits 100% rated power from −20°C through +50°C, decreasing to 50% at +70°C. Apply the input-voltage derating simultaneously.
Input-voltage power curve At 60 Hz: 85% rated power at 85 V AC; 90% at 90 V AC; 100% from 100 to 264 V AC. Follow the intermediate curve and the temperature limit together.
High-altitude derating For MP fan-cooled systems operating above 2000 m, reduce the allowable ambient temperature by an additional 5°C per 1000 m. Note 7 separately gives 3.5°C per 1000 m for fanless models; that fanless condition does not replace the MP fan-system requirement.
Temperature coefficient and vibration System temperature coefficient ±0.03%/°C over 0°C to +50°C. Vibration: 10–500 Hz, 2 G, 10 minutes per cycle; 60 minutes each along X, Y and Z axes.

Mechanical dimensions and connections

Module mechanical dimensions Module board drawing: 138 × 60 mm. Thickness reference 21 mm maximum; output-end projection 16 mm maximum and rear local projection 3 mm maximum. Dimensions are in mm; use the module drawing on PDF page 7 for connector orientation and clearances.
Output terminals and adjustment Two isolated output pairs: +V1 / GND1 for CH1 and +V2 / GND2 for CH2. M4 output screws; maximum mounting torque 18 kgf·cm. SVR5 adjusts CH1; SVR4 adjusts CH2.
CN41 remote connector JST B2B-ZR or equivalent: pin 1 +RC; pin 2 −RC. Mating housing JST ZHR-2; contact JST SZH-002T-P0.5, or equivalent.
Manufacturer warranty The MP series feature page states a 3-year manufacturer warranty.

Installation and system verification

Authorized assembly and power budgeting MP module assembly is restricted to factories certified by a safety agency and authorized by MEAN WELL in advance. Check the configured unit’s safety label. Keep the combined power actually used by all installed modules below the PFC front-end rating and within every selected module’s limits; available slots alone do not establish an allowable load.
Ventilation and mechanical support Keep cooling-fan vents unobstructed, with the manual’s recommended 10 cm clearance around the vents. Support the power supply with a suitable rack and use the mounting-hole arrangement shown; do not leave it cantilevered without adequate support. M4 mounting screws must penetrate the case by less than 6 mm; the drawing marks L = 6 mm maximum. This is insertion depth, not the overall screw length.
Input switching and restart Select any external input switch for a current rating greater than the system’s maximum inrush current. The manual recommends at least 10 seconds between power-off and restart so that the thermistor can cool; a warm restart can produce greater inrush. Apply input-voltage and ambient-temperature derating together.
Protection and servicing Use the selected module’s exact protection thresholds and recovery modes stated above. After overvoltage shutdown, remove the cause and allow 10 seconds with AC off before restarting. For overheating, the manual instructs the user to disconnect AC, remove the cause and cool the unit for approximately 10 minutes to 1 hour before restart; this service procedure is separate from automatic thermal-protection recovery. Fan lock, a broken fan wire or a loose connector shuts down all module outputs: disconnect AC and contact MEAN WELL or its distributor for repair.
Dual-output accessory boundary The accessory table lists FAS-001 for the one-slot MD-100 mechanical arrangement. The manual’s electrical series-operation section names MS modules, so that accessory listing alone does not authorize arbitrary series connection of MD-100 outputs. Confirm the exact dual-output assembly with MEAN WELL.
Complete-system EMC verification Install the component power supply in the intended final equipment and verify the complete system with representative loads, wiring and assembly. The datasheet’s EMC tests use a 720 × 360 mm metal plate, 1 mm thick; changes to the installation can affect results. The linked laboratory guidance does not grant finished-equipment certification or prescribe its example 40/80 cm laboratory geometry as product mounting clearances.
