August, 2017 Murata: Convection Cooled AC/DC Power Supplies
Mansfield, MA — Murata Power Solutions has developed a wide input range, single-output series of industrial/medical power supplies. The PQC series provides output power in an industry-stan- dard 1U, 3 x 5 in. (7.6 x 12.7 cm) open frame design. The high-efficiency supplies can deliver power with free-air natural convection cooling up to 50°C (122°F). The series has a universal AC input voltage range from 90 to 264 VAC, with any input from 47 to 62 Hz. The series is currently available in 12, 24, 36,
and 48V variants, each with a 5V standby as a standard feature. Additional output voltage vari- ants are currently under development, including a 54V model. With remote enable, the PQC series consumes less than 500 mW of power in standby mode. These power supplies can continuously deliver full output power across a wide tempera-
ture range of 0 to 50°C (0 to 122°F) and up to 70°C (158°F) with derating.
These power supplies carry medical, con-
sumer, and ITE safety approvals and incorporate 2xMOPP (means of patient protection) isolation. With an isolation of 4,000 VAC (input to output) or 1,500 VAC (input to PE), these units are excellent for powering such equipment as ultrasound moni- tors, blood pressure monitors, incubators, ECG equipment, and operating tables. Where an application requires more power or
redundancy, droop current share enables two or more power supplies to operate in parallel to increase output current capability and flexibility. The PQC250 complies with major interna- tional IEC/EN/UL 60950-1 safety standards and
PQC free-air convection cooled power supply.

VTI Expands Core ATE PXIe Functional Test Solutions
Irvine, CA — VTI Instruments, a business unit of AMETEK Program - mable Power, has introduced its EMX-75xx series of PXI express (PXIe) digital I/O modules, the latest addition to its core automated test equipment (Core ATE™) PXIe func- tional test solutions. The EMX-75xx series is a fami-
ly of high-performance PXIe modules that support multiple I/O configura- tions and logic levels. Dedicated input or output modules are avail- able for fixed high-channel-count applications. Other units provide flexibility with eight 8-bit ports (64 channels) that can be configured as either input or output. Modules are available with inter-
nal pull-up resistors that greatly sim- plify external cabling. Utilizing built- in clamping diodes, the EMX-7510 has the ability to sink up to 300 mA, mak- ing it useful for driving and sensing external devices, such as relays. Multiple logic levels are sup- ported, including TTL and LV TTL.

Internally supplied voltage levels of 3.3, 5, 12, and 24V, as well as user- defined voltage levels from 2 to 60V are also supported. In addition, 1,000V optical isolation is available for protection against damaging transient voltage levels. The EMX-7510 is built to deliv-
er a range of selectable voltages at 300 mA on each channel, including a voltage range from 2 to 60V (along with any values in that range), using
built-in clamping diodes. Contact: VTI Instruments
