Product Overview

The RSP-100 series delivers 100W with active PFC, universal AC input, and Class B EMC compliance - the sweet spot between RSP-75 and RSP-150. With 9 voltage options including unique 7.5V and 13.5V, fanless convection cooling, and an extended -30~70C operating range (wider than RSP-75's -25C minimum), it is the premium 100W enclosed solution for global compliance-critical applications.

Built around 100KHz PFC+PWM architecture, the RSP-100 achieves PF>0.98 at 115VAC with universal 85~264VAC input (no switch). EN61000-3-2 compliant for EU residential use, Class B EN55032 EMC, and 4KVAC I/P-O/P isolation. The 3.3V/5V/7.5V models support up to 5,000uF external output capacitance for demanding dynamic loads.

Measuring 179x99x30mm, the RSP-100 is slightly longer than RSP-75 (179 vs 159mm) to accommodate the higher power rating. It carries the same comprehensive certification portfolio: UL, TUV, CCC, BSMI, EAC, BIS (except 48V), and AS/NZS. Constant current overload protection with auto-recovery, remote ON/OFF via CN1, and 3-year warranty complete the premium feature set.

Frequently Asked Questions

How does the RSP-100 differ from the RSP-75?

The RSP-100 delivers 100W vs 75W - a 33% power increase. Key differences: (1) larger dimensions (179x99x30mm vs 159x97x30mm); (2) wider cold-start range (-30C vs -25C minimum); (3) 100KHz switching vs 65/80KHz - potentially lower audible noise; (4) supports 5,000uF external capacitance on 3.3V/5V/7.5V models; (5) 12V+ accuracy improved to +/-1.0% (vs +/-2.0% on RSP-75-12/13.5/15); (6) slightly lower 48V efficiency (88% vs 89%); (7) higher MTBF (2,325K vs 2,172K hrs). Choose RSP-100 when you need 100W, wider cold range, or large capacitive loads.

Can the RSP-100 be used in EU residential equipment?

Yes. Active PFC makes it EN61000-3-2 compliant with Class B EMC - legal for EU residential/commercial use without restrictions. This is the key advantage over LRS N2 and SE series.

What's the maximum external output capacitance?

For RSP-100-3.3, -5, and -7.5, the maximum recommended external output capacitance is 5,000uF. For 12V and above models, no specific limit is stated but keep within reasonable values for your load dynamics. Exceeding 5,000uF on low-voltage models may cause startup issues.

Is the 48V model BIS-certified for India?

No. The 48V model is excluded from BIS IS13252 certification. All other RSP-100 models are BIS-certified.

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

7.5V for legacy industrial controllers and medical devices. 13.5V is the standard float-charge voltage for 12V lead-acid batteries (13.5~13.8V), making the RSP-100-13.5 an ideal built-in charger for battery-backed systems. Both are rare voltages where the RSP-100 is often the only enclosed option with PFC.
