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. Under parallel operation ripple of the output voltage may be higher than the SPEC at light load condition. It will go back to normal ripple level once the output load is more than 5%.
4. Tolerance : includes set up tolerance, line regulation and load regulation.
5. Derating may be needed under low input voltages. Please check the derating curve for more details.
6. PV/PC functions when users are not operating on PMBus/CANBus. SVR functions when users are neither operating on PMBus/CANBus nor using PV/PC.
7. Output will shut down after O/P voltage is below < 80% of Vset for 5 sec, re-power on to recover.
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 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)
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

How does the RSP-1600-12 differ from the RSP-1500-12 at the same voltage and current?

The RSP-1600-12 delivers 12V at 125A (1500W) with a typical efficiency of 89%. It features a compact 1U chassis measuring 300 x 85 x 41 mm. The unit supports active current sharing up to 9600W (5+1 configuration).

What does the active current sharing (5+1) capability mean for system design?

Active current sharing (5+1) allows up to five RSP-1600-12 units to operate in parallel with balanced loads, delivering up to 625A at 12V combined. A sixth unit provides N+1 hot standby. This enables larger redundant 12V bus designs.

What industrial applications are appropriate for the RSP-1600-12?

The RSP-1600-12 delivers 12V at 125A (1500W) and is suited for factory control or automation apparatus, test and measurement instruments, laser related machines, aging facilities, digital broadcasting, constant current sources, and redundant systems. The 90–264VAC input supports worldwide single-phase supply.

What is the operating temperature range of the RSP-1600-12?

The RSP-1600-12 operates from -30°C to +70°C ambient. This range is suitable for cold-start applications in unheated enclosures. No IP rating is specified.

What certifications does the RSP-1600-12 carry?

The RSP-1600-12 holds UL62368-1, CAN/CSA C22.2 No. 62368-1, TUV BS EN/EN62368-1, BSMI CNS15598-1, AS/NZS62368.1, and EAC TP TC 004 approvals.
