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. Tolerance : includes set up tolerance, line regulation and load regulation.
4. Derating may be needed under low input voltages. Please check the derating curve for more details.
5. If use PV signal to adjust Vo, under certain operation conditions, ripple noise of Vo might go over rating defined in this specification.
6. FAN noise test set up according to ISO-7779.
7. 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 720mm*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)
8. The ambient temperature derating of 3.5℃/1000m with fanless models and of 5℃/1000m with fan models for operating altitude higher than 2000m(6500ft).

FAQ

What are the main output ratings of the Mean Well NSP-1600-36?

The NSP-1600-36 is a single-output enclosed AC/DC power supply rated for 36V DC output, 44.5A rated current, and 1602W power. It is designed as a compact 1U low-profile unit for high-power applications.

Is the NSP-1600-36 a good fit for industrial 36V systems?

Yes. This model is built for high-power industrial use where a regulated 36V DC supply is needed and the load stays within 44.5A and 1602W. Its enclosed design, built-in PFC, DC OK signal, and remote control features make it better suited to industrial equipment environments than basic general-purpose supplies.

Can the output voltage be adjusted on the NSP-1600-36?

Yes. The NSP-1600-36 supports programmable output voltage, which can be useful in systems that need tighter control around a nominal 36V rail. That makes it more flexible than fixed-output supplies that do not offer programmable adjustment.

What operating temperature range does the NSP-1600-36 support?

This model is rated for operation from -20°C to 70°C, with load derating at higher ambient temperatures per the derating curve. It uses forced-air cooling from a built-in fan with intelligent speed control based on the internal temperature, which is appropriate for higher-power enclosed power supply applications.

What protection features are included in the NSP-1600-36?

The NSP-1600-36 includes short circuit, overload, over voltage, and over temperature protection. These built-in protections are important for industrial systems that need a more robust power platform under varying load conditions.

What should buyers check before selecting the NSP-1600-36 for a system?

The main checks are whether the system requires a 36V DC output and whether total demand remains within 44.5A and 1602W. Buyers should also confirm that a compact 1U enclosed power supply with forced-air cooling and a 1.8 kg unit weight fits their equipment and reliability requirements.

What warranty and efficiency does the NSP-1600-36 offer?

Mean Well specifies a 5-year warranty for the NSP-1600-36. The unit also offers a typical efficiency of 91.5%, which helps support high-power operation in a compact enclosure.
