MeanWell LPS Power

Ever since the HDR-15/30/60/100 series (15W/30W/60W/100W) are released to the market, these new generation ultra slim step shape DIN rail power supplies have received high reputations from building automation and household control system. Now, MEANWELL is pleased to present the newHDR-100 series (100W) so as to meet the application requirements for higher output wattage. Manufactured with Class II isolation and meeting LPS (Limited Power Source) they conform to EN61000-3-2 Class A (the normal European Union regulation for harmonic current), and complying with safety regulations EN61558-2-16 UL508/UL60950-1, TUV, CB and CE. With Short circuit, Overload and Over voltage protections the HDR-100 series is supplied with a 3 year warranty.

This series follow HDR family features, adopting step shape plastic housing, accepting 85~264VAC input (277VAC operational), low no load power consumption (<0.3W), high working efficiency (90%), adjustable DC output voltage, wide working temperature range (-30~+70 degrees). They are isolation Class II level, passing LPS (Limited Power Source), conforming to EN61000-3-2 Class A (the norm the European Union regulates for harmonic current), and complying with complete safety regulations (UL60950-1, UL508, and EN61558-2-16); applying the European Union standard DIN EN43880 and slim design that the height are 90mm and the width are only 4SU (70mm). Thanks to its supreme features, complete safety regulations and competitive price advantages make HDR family your best choice in building automation, household control system, industrial control system and the electro-mechanical apparatuses applications!


A Limited Power Source (LPS) is a secondary circuit with an open circuit output voltage, not exceeding the SELV circuit limits of 42.4 VPEAK or 60 VDC. The maximum apparent power, available on the output under any load condition, and the maximum fault current, available on the output under any load condition, (including a short-circuit), are limited to magnitudes not likely to cause ignition under fault condition in components mounted on, or circuits constructed from, suitably rated materials.
