Mean Well DIN Rail Power Supplies — FAQs
What wattage range does the Mean Well HDR series cover?
The Mean Well HDR series DIN rail SMPS covers 15W to 150W, with a compact plastic case (1SU–6SU width per DIN EN 43880) and adjustable DC output voltage, suited to building automation and household appliance control.
What is the difference between Mean Well HDR and MDR series?
HDR is a compact, ultra-slim plastic-case unit (15W–150W) for general automation, while MDR (10W–96W) adds built-in active Power Factor Correction (PFC) and DC OK signal/relay outputs, and includes a variant rated for Class I, Division 2 hazardous locations.
Which Mean Well series is suited for high-wattage industrial loads?
The SDR series (75W–960W) and TDR series (240W–960W, 3-phase 340–550VAC input) are built for higher-wattage industrial loads, both offering built-in active PFC and up to 94.5% efficiency.
Does Mean Well offer adjustable-output DIN rail power supplies?
Yes, the DRA series (40W–60W) allows output current to be adjusted from 10–100% via 1–10 VDC, PWM signal or resistance, suited to machine vision and plant cultivation applications.
What safety and warranty coverage do Mean Well DIN rail supplies carry?
Depending on series, Mean Well DIN rail power supplies carry 2–3 year warranties (EDR, NDR) and meet EMC standards such as EN55022 Class A/B.
Can Mean Well power supplies handle wide 3-phase input voltage?
Yes, the WDR series accepts 1-phase and 2-phase wide input from 180–550VAC, and the TDR series is built for 3-phase 340–550VAC input, both with built-in active PFC.
