TT Electronics Introduces New Series of AC/DC Encapsulated Power Modules


TT Electronics has announced its new PAA and PAAM series of AC-DC encapsulated power modules with industry leading power density, ideal for space constrained industrial and medical electronic equipment applications. They offer more power per cubic inch and high efficiency by easing thermal challenges and improving system reliability.

The PAA/PAAM series is available in power ratings ranging from 5 to 150 Watts. The PAA encapsulated modules are PCB mountable in a compact footprint starting at 1.1 x 1.5 ” (8.05 W/in³). The 4 KVac input-output isolation provides safety when interfacing with downstream SELV networks. The modules boast exceptional conversion efficiencies of up to 89% and are free air convection cooled to improve end system reliability and reduce energy wastage.

The PAA series is IEC 62368-1 and IEC 60335-1 compliant which qualifies for industrial and smart appliances for the home environment where safety is critical. With footprint sizes starting at 1.1 x 2.1 ” (9.7 W/in³), the IEC 60601-1 approved medical-grade PAAM encapsulated power modules are available in 15 to 150 Watt options. Power densities in some models – including the industry-first 150 watt (PAAM150) – exceed 11 W/in³ and maintain conversion efficiencies as high as 93.5%.

“The PAA/PAAM series is an important addition to our already extensive medical power supply portfolio,” said Susan Cervenak, Director of Sales at TT Electronics. “These ultra compact encapsulated power modules provide OEMs with industry leading power density for a range of applications where space is at a premium and high efficiency and safety / EMC compliance is critical.”

The PAA/PAAM series offer standard output voltages from 3.3 VDC to 48 VDC and operate across a wide range of ambient temperatures. They are also fully certified to all applicable safety and EMC standards, reducing compliance risk, simplifying design-in, and accelerating end system time to market. The PAA series is suitable for industrial applications including automation equipment, EV charging systems and parcel locker stations while the PAAM series is ideal for portable medical devices, mobile clinical workstations and wider medical equipment.

Some PAA and PAAM module options are available in chassis mount package styles.
