Powering inductive loads like motors and electronic controls presents a unique challenge for engineers and technicians - the high startup currents can cause inefficiencies, oversized power supplies, and increased costs, all while struggling to maintain reliable operation.
Fortunately, power supply manufacturers like MEAN WELL continuously innovate to help you overcome power supply obstacles. The LRS-N2 and HRP-N3 series are the latest example of this, specifically designed for transient high peak loads without the need for oversized units.
The LRS-N2 series delivers up to 200% peak power for 5 seconds for robotic arms, motorized equipment, and emergency systems. But if that’s not enough, the HRP-N3 series takes things a step further with up to 350% peak power for demanding applications such as large industrial printers and complex machinery.

Why High Peak Load Capability Matters
Certain devices - those powered by motors or electronic controls - need a strong surge of power at startup or during transient periods. In many cases, the initial current draw can be several times the steady-state operating requirement.
Without the ability to handle these spikes, power supplies risk overload, shutdowns, or even permanent failure. This not only jeopardizes the power supply lifespan itself but also connected equipment performance and overall operational reliability/efficiency.
Manufacturing lines, medical equipment, or emergency systems are just a few applications where downtime is not an option, which is why a power supply with the most robust peak load capability is worth the investment.
Unfortunately, though, the solution isn’t as simple as oversizing your power source. Here’s why…
The Problem With Overkill Solutions
We see so many engineers and technicians turn to oversized power supplies that exceed their steady-state requirements. Sure, it’s a temporary fix for the issue - but it creates unnecessary problems over the course of time.
Oversized power supplies are not only more expensive upfront but also waste energy, generate excessive heat, and take up valuable installation space. Translation: higher operational costs, reduced system efficiency, and wasted resources.
Another workaround is paralleling multiple power supplies to achieve the required peak power. Again, though, this is suboptimal. It increases system complexity, introduces synchronization challenges, and eats into available space.
Similarly, staggering motor startups to reduce peak current can disrupt operational timing and compromise performance in systems that rely on simultaneous function.
To date, there has not been a “perfect” solution for these obstacles. That ends now, thanks to the introduction of the MEAN WELL LRS-N2 and HRP-N3 power supplies.
How the MEAN WELL LRS-N2 and HRP-N3 Series Improve Efficiency and Reduce Costs in These Scenarios
MEAN WELL is the #1 power supply manufacturer in the world for a number of reasons. One of these is the brand’s ability to seek out challenges like these and come up with intuitive solutions. After extensive R&D, we’re excited to help unveil the LRS-N2 and HRP-N3 Series.
Streamlined Design for Cost Reduction
Gone are the days of needing to over-purchase higher-wattage power supplies to handle peak loads. These units offer up to 200% peak power for the LRS-N2 series and 350% for the HRP-N3 series, reducing both the initial investment and ongoing operational costs.
Moreover, their compact form factor is compatible with the vast majority of existing setups. The LRS-N2 series has identical mechanical dimensions compared to previous models for seamless power supply replacement without costly modifications or downtime.
The HRP-N3 series takes cost efficiency further with its advanced power factor correction (PFC) capabilities. This leads to more energy waste reduction and improves overall system efficiency.
Improved System Efficiency and Performance
Efficiency is at the heart of the LRS-N2 and HRP-N3 series. These units accommodate high peak currents without increasing steady-state wattage, in turn optimizing energy usage during startup and transient periods.
Motor-driven applications like robotic arms or industrial conveyors, for example, will enjoy smooth operation without causing power disruptions or instability. We’ll examine more use cases for these units later on.
But we cannot stress the impressive power supply efficiency of these models enough. The HRP-N3 in particular offers efficiency levels exceeding 94%, which minimizes heat generation and reduces the strain on thermal management systems.
Other Technical Advantages of the LRS-N2 and HRP-N3 Series
The LRS-N2 and HRP-N3 Series are a powerful investment in peace of mind, knowing your most mission-critical devices or equipment are running smoothly around the clock. Here are some other technical advantages that have businesses worldwide so excited:
Peak Power Explained
You won’t find a solution that offers this level of peak power capability. The LRS-N2 series delivers up to 200% of its rated power for up to 5 seconds for applications with inductive or capacitive loads - like motor controls and electronic circuits with energy storage capacitors.
On the other hand, the HRP-N3 series offers an impressive 350% peak power for the same duration. It’s suitable for even more demanding uses like large printers or motorized medical devices.
You can choose a power supply based on steady-state needs while confidently managing high startup demands. This reduces both upfront costs and operational inefficiencies, leading to massive savings over the course of the unit’s lifespan.
Enhanced Protection Features
The power supply safety standards and protection features are second to none across the LRS-N2 and HRP-N3 series. You can rest assured your power supply itself and all connected devices are safeguarded for the long haul. Key protections include:
- Overload Protection: Prevents damage from excessive current draw during peak loads.
- Overvoltage Protection: Shields sensitive components from power surges (Overvoltage Category III).
- Overtemperature Protection: Automatic shutdown occurs if limits are exceeded, guaranteeing safe operation even under high thermal stress.
They’re compliant with IEC/BS EN/EN61558-1 and 62368-1. See the spec sheets for a specific model to learn more about specific safety standards.
Meanwhile, cooling by free air convection eliminates the noise and maintenance concerns associated with fans. They have an operating altitude of up to 4,000 meters and can withstand the 5G vibration test.
Just know that the MEAN WELL LRS-N2 and HRP-N3 series are resilient in even the most challenging, harsh operating environments. You can count on these units to work well without the risks of unexpected failures and costly downtime.
Advanced Monitoring and Control Options for HRP-N3
The HRP-N3 series is designed with precision in mind. It has features like DC OK signals, remote ON-OFF functionality, and remote sensing to integrate seamlessly into automated systems.
The models within this series also offer parallel operation with current sharing capabilities, enabling scalable solutions for high-power applications.
The built-in monitoring functions allow users to detect issues early, improving overall system reliability. It also has thermal fan control to minimize noise and energy use if need be.
Common Applications for the LRS-N2 and HRP-N3 Power Supplies
Just about any situation that calls for high peak power at startup or in transient periods can benefit from upgrading to the LRS-N2 and HRP-N3 power supplies. There are a few applications in particular we want to highlight.
Motorized Equipment
Applications like industrial conveyors, HVAC systems, and blenders may not seem to have anything in common - but they all demand a significant surge in power during startup.
