The medical power supplies’ global market is rapidly expanding. According to a MarketsandMarkets report ‘Medical Power Supply Market by Technology’, the sector, estimated at $642 million in 2012, is forecast to reach $866.8 million by 2017

What can OEM designers anticipate in power supplies and related power equipment, and how can they contribute to product success in today’s conditions, asks Andy Wall, Sunpower

Sunpower are pleased to announce today the release of the GS280 Series, a single output desktop adapter offering 280 Watts of power, a very low no load power consumption and up to 94% of high efficiency.

Sunpower’s PLEC-035S035DT power supply provides up to 100 VDC output at 350 mA. Its constant current capability makes it ideal for driving large LED lighting arrays. This 35 W supply automatically delivers a consistent, optimum current into a series string of any length from 9 to 28 LED lamps. Parallel LED strings can also be added, subject to the total output current capacity of the power supply. LED brightness can be set by a dimming control using a potentiometer or 0 – 10 Vdc input signal.

The Sunpower SPV Power Supply range is ideal for applications demanding highly controllable DC power. With power possibilities from 150W up to 4500W, the SPV outputs can be remotely trimmed over a very wide range – from 20% to 110% (120% for SPV-1500) of their nominal value of 12, 24 or 48VDC. The input specification is similarly flexible, with a wide range of AC and DC sources accepted.

Sunpower’s fanless DIN rail power supply family is ideal for applications ranging from industrial automation to domestic appliances. With output ratings from 10W up to 960W, these products efficiently match the power requirements of most panel builders. This wide power range is backed by a comprehensive set of features allowing very high power availability, reliability and efficiency, extended lifetime and reduced maintenance costs, compact installation solutions and minimal standby power consumption.

Sunpower’s CLG SERIES and PLN SERIES of power supplies offer a reliable choice for LED lighting applications. These UL1310 Class 2 power units feature environmental protection over extended temperatures, wide input and output voltage ranges for international use, and support for most LED types and installation designs. Built-in active power factor correction and high operating efficiency minimise users’ energy costs and carbon footprint.

Sunpower has re-designed its 100W Single Output Power Supplies to make more suitable for low consumption and environmental protection purposes. The newly designed circuit is built-in new PWM control IC which brings the max. output wattage up to 110W (for 48V output) under natural cooling environment.

Incorporating the same 88V ~ 264VAC or 125V ~375VDC input voltage as the single output models, and low

Sunpower's slim DIN rail product family, the SDR-480, is designed for the growing demand of high performance DIN rail power supplies in the market. Available with 24V or 48Vdc outputs and featuring 94%+ of extreme high efficiency, it can provide 480W continuously or 720W for 3 seconds at temperatures up to 60°C using only free air convection. With built-in active PFC function, SDR-480 is a full input range switching power supply that fulfils the requirement of EN61000-3-2 for harmonic current. The slim width design of 85.5mm helps save space on the rail and also makes it 51.8% smaller in size compare to its predecessor models.

The SPS-G075 Series comprises 75W Single Output Green Mode designed power supplies for low power consumption / environment protection purposes. Available in 5V, 12V, 25V, 24V, 30V & 48V models with a max. output wattage of 76.8W under natural cooling environment and 105°C capacitor built-in the power units works with wide range operating temperature from -20°C to +70°C.

New from Sunpower is the HRP series which combines high operating efficiency and low no load power consumption. HRP(G)-150 are 150W AC/DC miniature enclosed type power supplies with PFC function that fulfils the requirement of EN61000-3-2 for harmonic current. Featuring up to 89% of high efficiency, HRP(G)-150 can provide 150W continuously up to 50C using only free air convection.

Sunpower has announced a range of single, dual and triple output PCB type switching power supplies - RPS(G)-160 , RPD(G)-160, and RPT(G)-160 series targeting medical and IT applications with low profile requirements. The 5 x 3 PCB size has dominated the PCB-type power supply market for many years this new series perfectly fills the product gap for power supplies around 140~160W and provide end users with a more complete choice of power supply for all kinds of applications.

Sunpower UK has introducd the DR-15 series, a 12~15W single output Class II DIN rail switching power supply for the ever increasing demand of DIN rail applications. With Universal AC Input, no load power consumption

The RSP-3000 series from Sunpower is a 3000W enclosed type switching power supply with power factor correction (PFC) function - for the growing demand of high wattage applications. Featuring 15.6W/ in3 of extreme high power density, RSP-3000 series can provide full output power up to 50°C.

The newly designed circuit has a new built-in PWM control IC which brings the max. output wattage up to 52 watts, under natural cooling environments, from 3.3V, 5V, 7.5V, 12V, 15V, 24V, 30V and 48V outputs. With 105°C capacitor built-in, the power unit works with wide range operating temperature from -20°C to +70°C and the new mechanical design hexagonal cover makes for low air flow resistance and better cooling.
