75W switching regulated power supplies are convection cooled

75W switching regulated power supplies are convection cooled
Expanding the Narrow Profile, three-day power supply series of switching regulated power supplies, Acopian Power Supplies introduces the the WN8B power supply. The AC-DC single-output units provide an output power of up to 75W with convection cooling, which eliminates the need for fan maintenance, along with audible/ambient noise and vibrations.

Driver consumes 12 times less power than industry-standard

Driver consumes 12 times less power than industry-standard
Diodes Incorporated has introduced the ULN2003V12 and ULN2003F12A relay and inductive load sink drivers, providing seven and four channels, respectively. The ULN2003V12 consumes 12 times less power while offering a direct replacement to the industry-standard ULN2003A from other vendors, while the ULN2003F12A provides a smaller footprint when fewer output channels are required, such as when driving low-voltage stepper motors.

PSRR linear regulator's spot noise is only 2nV/√Hz at 10kHz

PSRR linear regulator's spot noise is only 2nV/√Hz at 10kHz
Linear has released the LT3042, a low noise, high Power Supply Ripple Rejection (PSRR) low dropout voltage linear regulator. Its design features low spot noise of only 2nV/√Hz at 10kHz and 0.8µVRMS integrated output noise across a 10Hz to 100kHz bandwidth. Low frequency PSRR exceeds 90dB out to 10kHz and high frequency PSRR exceeds 75dB out to 3MHz, quieting noisy or high ripple input supplies.

Pure sine wave inverters meet rail standards

Pure sine wave inverters meet rail standards
A series of pure sine wave inverters, which provide up to 3000VA of power, has been released by Schaefer. The PRP-3000 series of inverters features models that meet industrial and rail standards. Standard input voltages of 24, 36, 48, 72 and 110VDC are inverted to adjustable 120VAC or 230VAC outputs that are regulated to 4% or better. Units can be configured for three phase synchronisation.
