Test conditions and notes9

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. The efficiency is measured at 75% load.
6. If use PV signal to adjust Vo, under certain operating conditions, ripple noise of Vo might slightly go over rating defined in this specification.
7. FAN noise test set up according to ISO-7779.
8. 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 600mm*900mm 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)
9. 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 types of systems is the Mean Well NSP-3200-48 best suited for?

This 48V model is positioned for high-reliability applications such as industrial automation, telecom equipment, network systems, PoE power sourcing, security systems, and charging equipment. Its 48V output, 3216W rating and CANBus interface suit systems built around a 48V DC bus.

What input and output specifications matter most on the NSP-3200-48?

The product data identifies this as a 48V, 67A, 3216W output power supply. It accepts a universal 90-264VAC input range, or 127-400VDC, which helps when the same model needs to be used across different mains environments; output derating applies at low input voltages.

How does the NSP-3200-48 compare with other voltage versions in the NSP-3200 series?

The main difference is the output voltage: the series datasheet covers a 24V version (133A, 3192W) and this 48V version (67A, 3216W). The 48V version is the relevant choice when the end equipment is designed around a 48V DC bus, while both keep the same high-reliability enclosed format and feature set.

Does the NSP-3200-48 support remote monitoring or external control features?

Yes. The series includes remote ON/OFF control, remote sense with up to 0.5V compensation, DC-OK and T-Alarm signals for status monitoring, and a CANBus interface. Those features are useful in systems that need centralized control, voltage compensation, or power-good feedback.

Is the NSP-3200-48 designed for demanding environmental conditions?

It is designed for industrial use. The series uses a built-in fan with intelligent speed control based on internal temperature and is rated for -20°C to +70°C operation with derating at higher temperatures. Above 2000m altitude, the ambient temperature must be derated by 5°C per 1000m.

What protection and compliance features does the NSP-3200-48 include?

The series includes overload protection with constant current limiting, plus OVP (63-75V) and OTP protections. It is listed with UL62368-1, CSA C22.2 No. 62368-1, TUV BS EN/EN62368-1 and EAC TP TC 004 approvals, with EMC to EN55032 (conducted Class B, radiated Class A), EN55024 and EN61000-6-2.
