AC front end keeps it clean on the
powerline
Universal-input power module presents a near unity power factor to the incoming powerline, and generates a typical output of 393V DC.
Available now from UR Group, the Astec AIT02ZPFC is a 720W module with power factor correction that has a 61 x 89mm footprint and a mounting height of just 14mm, making it ideal for space-constrained applications The new AIT02ZPFC module features a universal input that accepts any voltage in the range 85 to 264V AC at any frequency from 47 to 63Hz and from 360 to 800Hz

Lightweight high-density switcher
Now available from Ultimate Renaissance are a range of highly efficient 60W AC/DC power supplies that provide power densities exceeding 7W/inch3 in a 50.8 x 101.6 x 20.3mm package.
Highest power density in class claim for switchers
New from UR (Ultimate Renaissance), EOS V-series switching power supplies pack up to 40W into a lightweight, open-frame unit occupying surface area similar to a regular business card.
The AIT02ZPFC module presents a near unity power factor to the incoming powerline, and generates a typical output of 393V DC, which is intended for feeding to one or more high voltage DC/DC convertors for further down-conversion to the low voltages required by the application.
UR Group can supply high performance, low profile AC/DC power supplies with minimal nonrecurring engineering costs and fast turnaround by using Emerson's modular high voltage half-brick and full-brick DC/DC convertors.
When fed with a 230V AC input, the AIT02ZPFC module has a typical power conversion efficiency of 93%; it can deliver up to 1.83A at 393V DC and achieves a power density in excess of 9.5W/cm3.
The module uses active power factor correction to minimise input harmonic current distortion and ensure compliance with the RTCA/DO-160D avionics standard at 115V AC at full load, and EN61000-3-2.
A number of built-in control and monitoring functions make the AIT02ZPFC module easy to integrate within a system.
Remote-enable and temperature monitoring functions are provided as standard, and the output voltage can be adjusted from 79-100% of nominal via a single control pin.
Inrush current is limited by an external resistor.
AIT02ZPFC modules are fully encapsulated and have an aluminium baseplate for conduction cooling.
They have no minimum load requirement and operate over a wide baseplate temperature range of -20 to +100C.
Input-to-baseplate and output-to-baseplate isolation is rated at 2700V DC, and leakage current is held to less than 3mA at 800Hz input frequency.
The modules are fully protected against overvoltage and overtemperature conditions and carry a full set of international safety agency approvals, including EN60950 TUV and UL/cUL60950.
