MEAN WELL NSP-1000 AC/DC Enclosed Type Power Supplies

MEAN WELL NSP-1000 AC/DC Enclosed Type Power Supplies feature 1000W rated power with PFC function, designed for high reliability and ideal for multiple industries. These devices feature 85VAC to 305VAC input with PFC (277VAC), up to 93% high efficiency, parallel output capacity up to 4000W(3+1), and 200% peak power capability. The NSP-1000 power supplies offer programmable output voltage from 0% to 120% and output current from 0% to 100%. These power supplies include a built-in constant-current limiting circuit and a built-in remote ON/OFF control/remote sense/DC OK signal with a wide operating temperature range of -40°C to 85℃. 

The NSP-1000 power supplies comply with Over-Voltage Category III (OVC III) and multiple safety standards, including ITE 62368-1, 60601-1, 60335-1, 61558-1/2-16/61010-1/-2-201, and 62477-1. These power supplies are available in a compact 230mm x 127mm x 41mm size for better space utilization in system installations. Typical applications include a supercapacitor, medical devices, home automation, power sourcing, security systems, electronic instruments, network equipment, telecom devices, and PoE power sourcing equipment.
