Test conditions and notes6

1. All parameters NOT specially mentioned are measured at 230VAC input, rated load and 25℃ of ambient temperature.
2. Ripple & noise are measured at 20MHz of bandwidth by using a 12" twisted pair-wire terminated with a 0.1uf & 47uf parallel capacitor.
3. Length of set up time is measured at cold first start. Turning ON/OFF the power supply very quickly may lead to increase of the set up time.
4. The power supply is considered a component which will be installed into a final equipment. All the EMC tests are been executed by mounting the unit on a 360mm*360mm metal plate with 1mm of thickness. The final equipment must be re-confirmed that it still meets EMC directives. For guidance on how to perform these EMC tests, please refer to “EMI testing of component power supplies.” (as available on https://www.meanwell.com//Upload/PDF/EMI_statement_en.pdf)
5. This power supply does not meet the harmonic current requirements outlined by BS EN/EN61000-3-2. Please do not use this power supply under the following conditions: a) the end-devices is used within the European Union, and b) the end-devices is connected to public mains supply with 220Vac or greater rated nominal voltage, and c) the power supply is: - installed in end-devices with average or continuous input power greater than 75W, or - belong to part of a lighting system Exception: Power supplies used within the following end-devices do not need to fulfill BS EN/EN61000-3-2 a) professional equipment with a total rated input power greater than 1000W; b) symmetrically controlled heating elements with a rated power less than or equal to 200W
6. RCM is on voluntary basis and meets relevant IEC or AS/NZS standards complying with AS/NZS 4417.1

FAQ

What types of equipment benefit from the LRS-350N2-24's peak power capability at 24V?

The LRS-350N2-24 outputs 24V at 14.6A (350.4W) and can deliver up to 200% peak power for up to 5 seconds (at 200–264VAC input, peak duty ≤35%, average power within the rating), making it well-matched for 24V stepper motor controllers, solenoid valves, and pneumatic actuator systems that pull high current at engagement but run at lower steady-state loads. The peak capability absorbs these short surges without triggering protection.

What is the operating temperature range of the LRS-350N2-24?

The LRS-350N2-24 operates from -25°C to +70°C, with the output derated at higher ambient temperatures (and further at 115VAC input) according to the datasheet derating curve. The 5G (10–500Hz) vibration rating makes it suitable for industrial panels that experience vibration in service.

Is 24V a common bus voltage for industrial automation, and does this supply meet those standards?

24VDC is the most prevalent control voltage in IEC-standard industrial automation, used for sensors, actuators, PLCs, and HMI panels. The LRS-350N2-24 complies with IEC/UL 62368-1, EN61558-1/EN61558-2-16, AS/NZS 62368.1, EAC TP TC 004, BSMI, BIS and GB 4943.1, satisfying the safety and compliance requirements typical of industrial control panel designs.

How does the LRS-350N2-24 compare across the LRS-350N2 family?

All four LRS-350N2 models share the 215 × 115 × 30 mm footprint, 0.76 kg weight, and 200% peak power feature. LRS-350N2-12: 348W, 29A. LRS-350N2-24: 350.4W, 14.6A. LRS-350N2-36: 349.2W, 9.7A. LRS-350N2-48: 350.4W, 7.3A. Select by the DC voltage level required by the connected equipment.
