Multi-Axis Alignment System from PI
AUBURN, MA — PI's family of photonics alignment automation systems has expanded with a new air-bearing-based multi-axis assembly and an EtherCat-based high-performance motion con- troller with embedded alignment algorithms. The unique combi-
nation of direct-drive maintenance-free air bearing alignment stages with sophisticat- ed first light search and alignment routines result in extraordinary time savings — a criti- cal factor in silicon pho- tonics alignment auto - mation. The F-143 align-
ment system is based on three A-143 air bearing stages in an XYZ config- uration. Each axis provides a travel range of 0.98 in. (25 mm), with a maximum velocity of 9.84 in. (250 mm/s), and acceleration up to 10 m/s2. Preloaded air bear- ings guarantee exceptional flat- ness and straightness of 0.25 and 0.05 µm, respectively. The verti- cal axis stage is equipped with an adjustable counterbalance and brake mechanism to offset the force of gravity on the motor and prevent potential collisions with a SiPh wafer in the event of a power failure.

faster than conventional optical alignment engines. The use of friction-free,
wear-free, and maintenance-free components along with the absence of lubricants makes the air bearing automated alignment system ideally suited for silicon photonics wafer probing and
other cleanroom applications. Contact: PI (Physik

Würth Elektronik Expands Transformer Series
WALDENBURG, GERMANY — Würth Elektronik presents new additions to the WE-AGDT series, with interwinding capaci- tance lower than 1 picofarad, more topologies and higher out- put voltage options. All trans- formers use the same compact SMT EP7 package. The WE-AGDT series is an
auxiliary gate drive trans- former series for up to 6W iso- lated auxiliary supplies target- ing gate drivers systems for SiC-MOSFETs and IGBTs. In these designs, the most crucial aspect is the transformer inter- winding capacitance due to the high dV/dt, which is common in designs utilizing wide-bandgap devices. The new additions to this
series feature interwinding capacitance is as low as 0.68 pF and output voltages as high as 30V. Options now include LLC, half-bridge, or flyback topologies and one or two outputs which can be used in either unipolar or bipolar applications. WE-AGDT complies with
the IEC62368-1/IEC61558-2-16 safety standard and is AEC- Q200 qualified. The transform- ers are suitable for use in indus- trial drives, AC motor inverters, HEV/EV charging stations, solar inverters, uninterruptible power

AC-DC Power Supplies from Polytron for EV Charging
PATERSON, NJ — The Polytron Division of Daburn Electronics
has introduced its PFEV series of AC-DC power modules for electric vehicle (EV) charger installations. The series comes in versions deliv- ering 20 to 150W of power — the most comprehensive choice of wattages available — and meets the latest overvoltage category (OVC) III requirements for safety. OVC III covers fixed instal-
lation equipment, such as EV chargers, that are hardwired to the AC mains supply where com- ponents may be susceptible to input voltage line transients caused by lightning or other sources of load instability. PFEV AC-DC power modules accept a wide 90 to 305 VAC universal input range and offer a wide range of outputs. No-load power consumption is less than 0.1W. The units comply with EMC standards without external com- ponents or filters and, due to their built-in coreless trans- former and compact, low on- resistance MOSFET, boast an exceptionally high power density
and up to 90 percent efficiency. Contact: Polytron Devices, Inc., 295 River Street, Suite 303,
