Mean Well is now offering its RSP-1500 series - a 1500 W enclosed type switching power supply with power factor correction (PFC) and parallel function - for the growing demand of high power applications. Featuring advanced ZVS technology and high power density (0,5 W per cc), RSP-1500 series can provide full output power even at 100 V a.c. input. With the trim function, output voltage can be adjusted from 75% to 100% rated voltage by adding external resistors. Besides the standard functions of remote sense, remote ON/OFF control, 12 V/0,1 A auxiliary output, and alarm signal output, RSP-1500 series uses constant current limiting plus delay shutdown as the overload protection which gives users the flexibility under applications of capacitive/inductive load - and still provides full protection for customers' system in the mean time. Applications include front-end power system, factory automation, instrumentation, moving sign, telecom/datacom, laser-carving machine.
Heavily invested in researching new circuit topologies, Mean Well continues to launch more new products supported by leading edge technologies. RSP-1500 is one of the examples that targets at the high-end large power market dominated by few big players in the past. The level of components, performance and quality are carefully considered during the design and manufacturing stage to ensure long lifetime of the power supplies.
A summary of the specifications:
* ZVS technology to reduce power dissipation.
* Universal AC input/full range.
* Built-in active PFC circuit compliance to EN61000-3-2.
