Product Overview

The RSP-75 series is MEAN WELL's premium 75W enclosed power supply with built-in active PFC - a key differentiator from the LRS and SE families. With universal 85~264VAC input (no switch needed), 9 voltage options from 3.3V to 48V, fanless convection cooling, and Class B EMC compliance, the RSP-75 is designed for applications where power quality, global regulatory compliance, and reliability are paramount.

The RSP-75 features active PFC achieving PF>0.98 at 115VAC and PF>0.93 at 230VAC, making it EN61000-3-2 harmonic current compliant - unlike LRS N2 and SE series which carry EN61000-3-2 restrictions. This means the RSP-75 can be legally used in EU residential and commercial equipment without needing exemption qualifications.

Measuring 159x97x30mm with convection cooling (no fan), the RSP-75 operates from -25C to +70C. It holds the most comprehensive certification portfolio: UL, TUV, CCC (China), BSMI (Taiwan), EAC (Eurasia), BIS (India, except 48V), and AS/NZS (Australia/New Zealand). I/P-O/P withstand is 4KVAC - higher than SE/LRS series.

The 9 voltage options include unique 7.5V and 13.5V models not available in most competing 75W supplies. Protection uses constant current limiting (auto-recovery for overload) which is more forgiving than the latch-off protection used in SE series. Remote ON/OFF via CN1 connector, LED power indicator, and 3-year warranty complete the premium feature set.

Frequently Asked Questions

What makes the RSP-75 different from the LRS-75 or LRS-100N2?

The RSP-75 is a premium product line with three critical advantages: (1) Active PFC (PF>0.98) making it EN61000-3-2 compliant for EU residential use - LRS N2 and SE series are NOT compliant and carry usage restrictions; (2) Class B EMC for residential/commercial deployment vs Class A (industrial only) on LRS/SE; (3) Universal AC input (85~264VAC) with no switch to set, eliminating configuration errors. Additionally, RSP-75 offers 9 voltage options (vs 4 for LRS-100N2), TUV/CCC certifications, and 4KVAC isolation. Choose RSP-75 for global regulatory compliance, EU residential applications, and noise-sensitive environments.

Can the RSP-75 be used in EU residential equipment?

Yes. This is a key advantage. The built-in active PFC makes the RSP-75 EN61000-3-2 compliant with Class B EMC emissions, meaning it CAN be legally used in EU residential and commercial equipment - unlike LRS N2 and SE series which carry EN61000-3-2 restrictions. This eliminates the need for exemption qualifications or additional filtering.

What are the 7.5V and 13.5V models used for?

7.5V is commonly used in legacy industrial controllers, some medical devices, and custom automation equipment. 13.5V is the standard float-charge voltage for 12V lead-acid batteries (13.5~13.8V), making the RSP-75-13.5 an ideal built-in charger for battery-backed systems. Both are rare voltages that make the RSP-75 the go-to choice when you need them.

Is the 48V model BIS-certified for India?

No. The 48V model is excluded from BIS IS13252 certification. All other RSP-75 models (3.3V through 27V) are BIS-certified for the Indian market.

How does the constant current overload protection work?

Unlike SE series which latch off and require a power cycle, the RSP-75 uses constant current limiting: when the load exceeds 105~135% of rated power, the output current is clamped to a safe level while voltage drops. Once the overload condition is removed, the output automatically recovers to normal regulation - no manual intervention needed. This is ideal for motor startup and capacitive loads where momentary overload is expected.
