Test conditions and notes8

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. Voltage adjustment can only be operated within the input range of 100~120VAC or 200-240VAC. If the voltage adjustment is performed outside this range, it may cause abnormal output.
4. Length of set up time is measured at cold start. Turning the power supply on/off frequently may lead to increase of the set up time.
5. Once protections are triggered, 4min(Typ.) of cold down time is required before restart.
6. 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)
7. This power supply does not meet the harmonic current requirements outlined by 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 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
8. RCM is on voluntary basis and meets relevant IEC or AS/NZS standards complying with AS/NZS 4417.1

FAQ

What is the peak power capability of the LRS-600N2-12 and when does it activate?

The LRS-600N2-12 can deliver up to 200% of its rated 600W output (approximately 1200W) for peaks of up to 5 seconds, at a duty cycle of no more than 35% and with average power kept within the 600W rating; the available peak level depends on input voltage (see the peak-power curve). This covers short surges such as motor startup, capacitor charging, or solenoid engagement without requiring a larger continuous-rated supply.

How does the LRS-600N2-12 compare to the other LRS-600N2 voltage variants?

All LRS-600N2 models share the same 225 × 124 × 41 mm case, 0.95 kg weight, 90–132VAC / 180–264VAC switch-selectable input, and 200% peak power capability. Output ratings: LRS-600N2-12 (600W, 50A at 12V), LRS-600N2-24 (600W, 25A at 24V), LRS-600N2-36 (597.6W, 16.6A at 36V), LRS-600N2-48 (600W, 12.5A at 48V).

What temperature range does the LRS-600N2-12 support?

The LRS-600N2-12 operates from -20°C to +65°C ambient, with output derated at higher temperatures according to the derating curve; enclosures should be designed with adequate airflow to keep the unit within its derated load limits. The -20°C lower limit supports operation in most industrial indoor environments.

Is the LRS-600N2-12 appropriate for motor-driven automation systems with frequent start-stop cycles?

Yes, within its peak limits. The combination of 50A continuous output and 200% peak power for up to 5 seconds (duty cycle ≤35%, average power within the 600W rating) makes the LRS-600N2-12 well-matched for 12V DC motor systems with startup inrush. The peak feature absorbs short startup surges that would otherwise require oversizing to a higher-wattage supply.
