LD015D power supply
Power Sources Unlimited has announced the LD015D Series AC-DC Constant Current LED driver power supply, which is fully potted and suitable for dry and damp locations.
It adheres to UL1310 Class 2 Safety Standards (110V AC) or CE compliancy (230V AC).
Features include input voltage of 110 or 230V AC, DC output ranges from 8 to 48V DC and wide selection of pre-adjusted constant current outputs.
Other features include: operating temperature range of -20 to 60C, phase dimmable, compatible with standard Triac and electronic low-voltage dimmers; and 82 per cent efficient typical.
Units are RoHS compliant, Reach compliant, FCC Class B, CE, EN61000-4, 2, 3, 4, 5, 6, 8, 11 and UL.cUL safety certified, and carry a three-year warranty.
The Eltek Valere Flatpack2 HE Series of rectifiers has been introduced into the global telecommunications market, offering a conversion efficiency up to 96.5 per cent and a 50 per cent reduction in wasted energy, according to Power Sources Unlimited.
The LTC3624 is a high-efficiency, 17V-input-capable synchronous buck regulator from Linear Technology that delivers up to 2A of continuous output current to outputs as low as 0.6V. Synchronous rectification delivers efficiencies as high as 95 per cent, while Burst Mode operation requires only 3.5µA of no-load quiescent current.
Dewetron has introduced Linux system-level drivers for its Trion series of A/D+ signal conditioning modules and an API for the Trion series that is available for both Linux and Windows.
This document from Power Integrations describes an isolated high-power-factor TRIAC-dimmable LED driver that utilises the LYT4317E from the LYTSwitch range of ICs.
Linear Technology has introduced the LTC6431-20: a 20MHz to 2GHz single-ended input and output fixed-gain amplifier that offers a 46.2dBm OIP3 (output third-order intercept) and a 2.6dB noise figure. Two grades are offered, including the A-grade version that has a minimum of 42.2dBm OIP3 at 240MHz and the B-grade version that has a typical OIP3 of 45.7dBm at the same frequency.
