ABB launches 22kW EV charger for the home
ABB has launched a connected AC charger for electric vehicles
(EVs) in the home. The Terra AC wallbox is available in up to
22kW variants to ensure compatibility with the electrical system
of homes and buildings
across the world.
It also includes a high
accuracy revenue
grade energy meter
that can be integrated
with smart building
energy management
systems for load
management. This
enables home and
business owners to adjust the power of assets as needed to
maximize charging power and cost efficiency. The EV charger
has multiple connectors available such as CCS2, CHAdeMO
and Type 42 to make it compatible with the majority of EVs,
using the experience from ABB’s commercial charger systems.
“The trends of urbanization, digitalization and industrialization
all converged to necessitate a significant shift in the way we
travel. Already leading the DC fast charging market, we recognized
the need to draw on our extensive experience to develop
a game changing AC solution for overnight or longer duration
charging in homes and businesses,” said Frank Muehlon, Head
of ABB’s global business for E-mobility Infrastructure Solutions.

Non-isolated DC-DC converter in SMD LGA
package for 48V designs
Recom has launched a 500mA non-isolated DC-DC converter
and switching regulator in a surface mount LGA package with
an input range from 4.3V up to
65V and five trimmable output
options. The RPMH-0.5 series
expands the RPM range in a
standard 12.19x12.19x3.75mm
DOSA-compatible thermallyenhanced
low profile LGA package.
There are five trimmable
fixed outputs available: 3.3V (+10%/-20%), 5V (+10 percent/-20
percent), 12V (+10 percent/-40 percent), 15V (+10 percent/-40
percent) or 24V (+17 percent/ -37 percent). The input voltage
range is 1V to 1.5V above the set output up to 65V, making the
parts suitable for systems operating on nominal 5, 12, 24 or
48V rails. The thermal management means that the RPMH-0.5
series operates from -40°C up to 95°C (100°C) ambient with full
load and convection cooling only. Efficiency is up to 89 percent
allowing the full 500mA output current to be delivered across
the entire input voltage range. Efficiency is also high at very low
loads, which, combined with very low quiescent current down to
16μA (3.3V and 5V versions), makes this series suitable for applications
that have ‘sleep’ modes such as microcontrollers and
transceivers.The RPMH also has 6-sided shielding for low radiated
EMI so ‘Class B‘ EMI compliance is achieved with a simple
low cost line inductor.

Small modular 600W and 1200W
configurable power supplies
FiDUS Power’s NEVO modular 600W and 1200W configurable
power supplies have medical variants. Both sizes of the NEVO
configurable power supplies
are available with the
latest in medical safety
approvals for safety EN/
IEC/ANSI 60601-1 and
EMC immunity EN60601-
1-2 4th edition and
comply with EN55022
level B EMC Standards.
The 600W output NEVO+600 measures 5 x 3 x 1.61in and the
NEVO+1200 measures 6 x 6 x 1.61in with 1200W. The units
fit into a 1U enclosure with robust enclosed mechanics. Both
models have ITE and medical variants with analogue current
and voltage programming, analogue current output signal, 5V
bias supply (one per card, one per 600W chassis and two on
the 1200 chassis), global / local inhibit, AC OK and DC OK
power good signals. Accurate current sharing across multiple
modules is a standard feature enabling them to be used in the
most demanding applications where a large output current of
up to 100A is required. Outputs can also easily be configured
in series to support applications requiring high voltages of up
to 240VDC. The configurable power supplies use an integrated
fan with a low noise option for sound sensitive applications.

600W medical AC-DC power supply
measures 76.2x127x37mm
The 600W TDK-Lambda CUS600M AC-DC power supply has
an efficiency of 96 percent which minimises the internal heating
and allows it to fit into a
standard 3 x 5in footprint.
The AC-DC power supply
series is certified to the
medical and ITE (Information
Technology Equipment)
standards for Class
I and II (no earth ground
connection) operation.
These can be used in
medical, home healthcare, dental, test and measurement,
broadcast, professional audio and industrial equipment. There
are seven standard output voltages available in the AC-DC
power supply series, from 12V, 19V, 24V, 28V, 32V and 36V to
48V. All the power supplies have an 85 to 264Vac input and
have a no-load power consumption of less than 500mW when
the output is inhibited. A 5V, 2A standby voltage, remote on/off,
remote sense and a power good signal are fitted as standard.
A cover with a fan option is available. The open frame models
measure 76.2 x 127 x 37mm with the cover/fan assembly. With
convection cooling, the CUS600M provides 400W (600W peak)
in -20°C to +40°C ambient temperatures, derating linearly to
200W load at +70°C. With forced air cooling the series provides
600W at +55°C ambient, derating to 420W at +70°C.
