Würth Elektronik Expands Terminal Block Family
Waldenburg, Germany — Würth Elektronik eiSos has launched its WR-TBL series of terminal blocks that no longer require cables to be stripped. This development was made possible by an insulation- displacement technique used in the series. The terminal blocks
are supplied in the 3.81 and 5.08 mm (0.15 and 0.2 in.) spacing pitches, with and without
flanging.
According to the cULus method, maximum cur- rent capacity is 5A/300 VAC for the 3.81 mm ver- sion and 7A/300 VAC for the 5.08 mm version. Cable cross-sec- tions are available in sizes of 3.81 mm, 2220 AWG (0.326-0.518 mm2); and 5.08 mm, 2218 AWG (0.626- 0.823 mm2).

Powerbox: DC-DC Converters for Automotive IoT
RoHS
Bedford, NH — Powerbox, a power supply company that specializes in devices for demanding applications, has launched a new series of power supplies for automotive applications and onboard Internet of Things (IoT). Based on a highly-integrated compo- nents platform and low-profile planar magnetics, the new series ENA100 (100W) and ENA200 (200W) are pack- aged in an IP21 plastic enclosure, and the boards are conformally-coated to withstand high humidity, to meet the challenging requirements of the auto- motive industry. To guarantee high levels of effi-
ciency and reliability, the ENA100 and ENA200 power stage uses specific components selected for robustness and high-reliability data and operate within a safe-band area. The series comes with galvanic isolation of 500 VDC and built-in protections and fil- tering, making the products ready to use without additional components. The
automotive industry
requires flexible power solutions that deliver stable voltage and are immune to line disturbances, while including a growing number of con- nected devices and Internet of Things applications. From geo-local- ization systems installed in a fleet of vehicles, to latest generation of buses equipped with video-on-demand per seat and high-speed internet connec- tions, the automotive industry is requiring new generations of power supply technology, simple to install and operate, and in standardized packaging. As members of the Powerbox
Automotive Line, the units have been designed in response to the automo- tive industry’s demand for standard- ized DC-DC converters built in low- profile packaging lower than 20 mm (0.8 in.), isolated cases with an IP- class of 21, galvanic isolation, low con- ducted and radiated EMI, and with the capability to handle 2 kV surges. Along with the power supplies’ simple installation, they can be upgraded if more power is required. Packaged in a 116 x 88 x 18 mm
(4.57 x 3.46 x 0.70 in.) polycarbonate housing, the ENA100 and ENA200
baseplate includes four mounting holes for mechanical attachment to a vehicle chassis or assembly plate. The low weight — less than 500 grams — contributes to its performance in vibration testing (5-50 Hz, accelera- tion ±7.35 m/s2). The input and output of the supplies have 6.3 mm (0.25 in.) industry-standard connectors, along

with an integrated LED, which indi- cates the state of the output voltage. The ENA100 and ENA200
series cover a large range of applica- tions requirements from 10 VDC input up to 120 VDC. Four output voltages, 12.5, 14.5, 24.5, and 28 will be available and, depending on the output voltage, in a range of output currents of 8 to 16A. The ENA100 and ENA200 have efficiencies of up to 96 percent. Ready-to-use products, the ENA100 and ENA200 series incorporate efficient input filtering, short circuit protection with constant current limit set at approximately 110 percent, temperature protection with automatic recovery, and intelli- gent power control, which provides safe-gap operation. Designed for con- duction cooling, the two series can be operated from –20 to +50°C (–4 to 122°F) ambient and up to 70°C (158°F) baseplate. Meeting road vehicle EMC and transient protec- tion, the power supplies comply with the standards EN61000-6-2; 4- 2/3/4/5/6 and are EMI EN55022B conducted and radiated. The supplies also comply with ISO7637-2 and
EN12895:2000. Contact: Powerbox USA, Inc., 15 Constitution Drive, First Floor,
