90- to 528-V Input 3W AC-DC Power

Mornsun has released new 3W three-phase four-wire ac-dc converters in the LS03-16BxxSS and LD03-16Bxx series. The series offer 90- to 528-Vac wide input range, ac and ac dual-use (input from the same terminal) and requirements of 3x220Vac/380Vac nominal voltage and any two-wire connection from three-phase four-wire system, meeting UL60950/EN60950/FCC part 15 standards.

The series provide high efficiency up to 76%, 4000Vac isolation and output short-circuit and over-current protections. This series of products remain cost effective while offering high reliability and excellent performance. With SIP and DIP packages available, they are suitable for various applications, especially for space constrained applications such as: Three-phase electric meter, industrial control, instrumentation, double power switch controller, fire protection system, etc.

Features and specifications include: Suitable for any two-wire connection from three-phase four-wire system; Input voltage range: 90- to 528-Vac or 100- to 745-Vdc; Operating temperature of -40 to +85 degrees C; Isolation of 4000Vac (SIP)/ 3000Vac (DIP); Efficiency up to 76%; Meet UL60950/EN60950/FCC part 15 standards (pending); and Output short-circuit and over-current protections.
