SD range of converters (shown above)
The Meanwell SD series of DC to DC switch-mode converters provide an industrial style enclosed power supply that operates from batteries or other DC sources. e.g. 12V, 24V, 48V or 120V. They come in wattages of 15W, 25W, 50W, 100W, 150W, 200W, 350W, 500W and 1000W and in output voltages of 5V, 12V (10V to 16V), 24V (22V to 30V) and 48V (45V to 60V). Refer to the standard range of industrial 110VAC to 240VAC power supplies for DC voltage inputs of 120VDC to 370VDC or the DIN mounted range DRH, DRT and WDR for voltages up to 780VDC - click here. All SD converters have a 2 year warranty. SD-500 and SD-1000 have a 3 year warranty. All units (except SD-1000) may be DIN rail mounted using hardware available from Meanwell. Applications include: Efficient conversion of 24V battery power in trucks and other vehicles to 12VDC or other regulated voltages. DC-DC converters also provide isolation between voltage source and load (prevents earth loops) and can be used to provide a remote DC voltage that's properly regulated (e.g. when long cables cause poor regulation, noise and voltage drop).

TS range of inverters (shown above)
The Meanwell TS range provide a True Sine Wave (TSW) DC to AC power inverters in 400, 700, 1000 Watts with 240VAC output. These inverters can be used in continuous operation and at high temperatures (100% load at 40°C derated to 50% load at 60°C). Each inverter can be supplied in 12V or 24V DC input and each has a standby saving mode and adjustable output. i.e. 200, 220, 230, 240VAC and 50 or 60 Hz. The Meanwell TSW inverters provide low noise operation of audio equipment (Hi Fi, TV, satelite receiver, radio equipment). And they work best with most appliances, including flourescent lights, incandescent lamps (inc. dimmer), laptop or desktop computer equipment (LCD display and ink-jet printer recommended), telephone equipment and most small appliances - we ran our 150w 26 inch CRT TV, Hi Fi, digital set top box, DVD player and Wii game console all from one TS-400 unit during an 8 hour power shutdown! Motor driven tools and equipment that start under no-load conditions (fans, vacuum cleaner, drills, saws, grass trimmers, hedge trimmers) work well with these inverters even if they are speed controlled and also when motors are rated higher in wattage than the inverter! Motors which start under heavy load conditions such as compressors and pumps normally will not work with an inverter because they require up to 10 times the current at start up! However, "soft-start" air-conditioners and refrigerators and some small units may work - please consult the manufacturer. A Meanwell TSW inverter will ensure that motors run cooler, microwaves cook faster and clocks keep better time! They are useful in caravan, mobile home or motorhome applications as well as for emergency power in the home, office, farm or factory. Other applications include - yachts or boats, trucks, tractors and remote location etc.

Now available is the RSD-150 with Over Temperature Protection (OTP) making it suitable for battery charging! Coming soon is the RSD-200.
