XP Power announces the ECE80 series of 80-W single-output ac/dc encapsulated power supply modules with high efficiency and a low no-load input power. The modules target customers requiring an encapsulated ac/dc power solution in an ultra-compact format for either PCB, chassis, or DIN-rail mounting.
The modules suit Class II applications and offer Class B EMI protection without any additional filtering. Applications include those in automation and process control, broadcast, instrumentation, mobile communications, and home automation. The supplies provide peak load capability of up to 130% of nominal rated power output for 30 s, and can power short-term higher power loads, so designers may not need to specify a higher-rated and possible physically larger power supply. The power supplies have a power density of >11.2 W/in.3 and offer five standard output voltages from 12 to 48 Vdc. The PCB mount module measures 3.60 x 1.80 x 1.10 in. and the chassis mount module measures 4.45 x 1.87 x 1.12 in. They feature a no-load power consumption of <0.3 W and efficiency up to 89%.
The operating temperature range extends from –40°C to 70°C (with no derating until 50°C). The modules are able to operate in most environments with no need for additional heat sinking or airflow. They meet Class B-conducted and -radiated EMC limits without any additional components and are UL/CSA/EN/IEC 60950-1 safety agency approved.
