UPS system saves more than 30% in floor space
Designed for small and medium power requirements seeking greater cost control, flexibility, optimisation and speed of deployment, the Liebert eXM UPS system has been released by Emerson Network Power. The 3-phase UPS will be available in North America (including Canada), Central America and Latin America in March in eight fixed capacities from 10 to 100kVA/kW, in 208 and 220V.
PVM controllers simplify design & speed time-to-market
ZMDI has released the first six products of the ZSPM15xx family of single-phase true-digital power solutions for non-isolated, high-current POL applications. The company collaborated with Würth Elektronik on this project, optimising the ZSPM15xx family for Würth high performance inductors.
Power supply targets secure bulk power applications
Designed for secure bulk power applications, the 800W M1V2-5801V4H 1+1 micro redundant industrial PC power supply has been released by Stadium Power. Measuring 355x106x41.8mm, the device operates across a 90-264VAC universal input voltage range with a typical efficiency of 88% at 230VAC. The UL, CUL and TUV approved power supply operates across a temperature range of 0 to 50°C.
DC/DC converter module supplies RF power amplifiers
Designed to supply the voltage to power transistors that are used in integrated Radio-Frequency Power Amplifier (RFPA) applications, Ericsson has launched a 200W DC/DC converter module in an eighth-brick format. The PKB4216C series module offers flexibility with its adjustable output voltage of 15-33V, which makes it possible to power a wide range of power transistors.
Wireless charging charges ahead
Will removing division in the industry help promote wireless charging to greater heights? Philip Ling takes a look at the latest developments.
Smaller input range saves LED power supply cost
Mean Well has announced that its PLM-12/25 PFC constant current mode LED power supplies have garnered outstanding feedback since their release. In order to target demand from areas that only use 230VAC input, Mean Well has modified the input voltage range from 110-295VAC to 180-295VAC for its latest release, the competitively priced PLM-12E/25E series.
Controllers power next-gen enterprise networking equipment
ZMDI has released the ZSPM1505 and ZSPM1506 single–phase true–digital power controllers, which are optimised for powering auxiliary power rails for FPGAs in enterprise networking and storage applications. These devices expand the company’s energy-efficient Power Management ICs product line for enterprise networking and storage applications.
Optocouplers protect & drive SiC & GaN power devices
Avago has announced two sets of high speed gate drive optocoupler devices, the ACPL-P/W347 and ACPL-P/W349. These devices are 1.0A and 2.5A gate drive optocouplers designed to protect and drive fast switching next-gen power semiconductors like SiC and GaN MOSFETs and IGBTs in applications such as power inverters, motor drives, and switching power supplies.
Linear voltage regulators operate up to +175°C
A fixed-5V linear voltage regulator ruggedised for high reliability and high temperature automotive and industrial applications, the CMT-ANTARES, has been unveiled by CISSOID. The device delivers up to 200mA to the output load from input voltages between 5.5 and 30V over a temperature range from -55 to +175°C.
Digital power controller minimises output voltage deviation
The ZSPM1504, a single-phase true-digital power controller optimised for powering SoC supplies in embedded computing applications, has been released by ZMDI. The ZSPM15xx family features ZMDI’s Sub-Cycle Response technique to drive the digital pulse width modulation asynchronously during load transients. This enables the controller to minimise the output voltage deviation and allow the output capacitors to recharge faster. It permits t...
