Advanced Energy Industries is showing its NP08 4kW ac-dc power supply at APEC in Long Beach this week. The first member of its NeoPower (NP) family of configurable multi-output supplies, it has eight output slots for configuration and 18W/inch3 claimed density for ~283 x 203 x 64mm chassis. Input is single-phase 90 – 132Vac and 180 – 264Vac. “NP08 also ...

Cosel has announced a series of ac-dc power supplies with enhanced reliability for industrial applications. Called the PDA series, the PSUs are form, fit and function backwards compatible with the company’s 20 year old PBA series, with fewer internal components explaining part of the reliability increase. With more to follow, the initial versions are: PDA15F (15W 31 x 78 x 85mm), ...

NGK Insulators has teamed up with Rohm to produce a complete energy storage evaluation kit for IoT devices including shelf-edge labels. Called REFLVBMS001-EVK-001, it measures 56 x 32 x 1.6mm and the components, including the battery, stand a maximum of 1mm above the PCB. It can accept power at 4.5 to 5.5V, and outputs up to 500mA at one of ...

Vox Power has introduced a compact 600W modular ac-dc power supply with four output slots, and a choice of eight output modules that can be mixed and matched among them. NEVO+600S is the name, and it measures ~41 x 78 x 134mm (plus blade terminals), giving it a 5 x 3inch footprint. “Tailored for demanding industrial applications where size, power ...

Vox Power has announced a set of conduction-cooled 300W dc-dc converters, for railway and other rugged environment use. Measuring 188.6 x 116 x 25.4, the 33.6 to 160V input range is intended to cover 48, 72, 96 and 110 V railway batteries. Dips to 28.8V can be ridden through covered for 100ms, complete drop-outs for 10ms, and 168V peaks for 1s. ...

Power IC company Cambridge GaN Devices (CGD) has signed a deal to develop power adapters and data centre PSUs with Chicony Power Technology of Taiwan, and Cambridge University Technical Services (CUTS). “Chicony Power is one of the leading SMPS manufacturers in the world, so this agreement represents an incredible milestone in CGD’s journey,” said CGD CEO Giorgia Longobardi. “Chicony Power ...

Cosel has used GaN transistors, planar magnetics and a modified fly-back topology to shrink a family of dc-dc power supplies. Called the TE series, the new supplies come in 45W (TECS45F and TEPS45F) and a 65W (TECS65F or TEPS65F) forms. TEPS versions have connections brought out to PCB pins and have a 1 x 2.3inch footprint, while TECS parts (right) ...

Power Integrations has introduced a 1,250V GaN version of its Innoswitch family of off-line constant-voltage constant-current quasi-resonant fly-back switcher ICs, making the options: 725V silicon, 750, 900 or 1.25kV GaN or 1.7kV silicon carbide. These are multi-die devices in a single package, with synchronous output and a proprietary inductive isolated feedback technique using bond-wires. The new devices have been dubbed ...

Powerbox has announced a ruggedised 1,200W ac-dc power supply for ground-based defense applications and harsh industrial environments. Called OFD1200A and suitable for use inside sealed enclosures, it has a metal chassis and requires cooling by conduction though its baseplate – which needs to be maintained between -40 and +95°C (derating applies sometimes – see the product manual). Shock and vibration ...

STMicroelectronics has combined two LDOs, a CAN FD transceiver, four PWM-able high-side switches, a watchdog timer and a LIN transceiver into a single automotive-grade power IC. Called SPSB081, its aim is to provide a companion microcontroller with power, two serial interface transceivers, battery-voltage high-side load drivers and power for its peripherals. There are four devices giving 5V or 3.3V from ...
