SD range of DC-DC converters (above left)
The Meanwell SD series of switch-mode DC to DC converters provide an industrial style enclosed power supply that operates from batteries or other DC sources. e.g. 12V (option A), 24V (B/L), 48V (C/L) and 96V or 120V (D/H). Note the SD-100D and SD-150D also allows 85-132VAC operation! The SD range comes in wattages of 15W, 25W, 50W, 100W, 150W, 200W, 350W, 500W and 1000W and in output voltages of 5V, 12V (10V to 16V), 24V (21V to 30V) and 48V (45V to 53/60V). 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. Most SD units may be DIN rail mounted and surface mounted using hardware available from Meanwell - click here. 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).

RSD series DC-DC converters (above centre)
The Meanwell RSD range of DC to DC converters and are designed for low power railway and mobile (metro, subway, bus, tram...) applications. Suitable for cabin electrical equipment, radio communications and entertainment equipment, ticketing systems, video surveillance equipment and low voltage LED lighting on trains and in other public locations. In addition, they are also suitable for harsh industrial installations where dust and moisture are a concern, such as security systems, DC UPS systems, and telecommunications etc. The RSD-100 is designed as a direct replacement for the Absopulse range of MIM-50R converters. Nominal input voltages include 24V, 48V or 96V-110V DC (36V and 72V with RSD-300) with wide (EN-50155) input ranges. The RSD-100 unit delivers 100 Watt DC at 5V (20A), 12V (8.4A) or 24V (4.2A). This unit is housed in a compact 68 x 36 x 161mm vented chassis-mounted enclosure, and weighs 600g. It operates over -40°C to +70°C with no derating if mounted on a base plate. The RSD series meets the requirements for the EN50155 railway certificate (also IEC60571, IEC61373, EN50121-3-2) for electronic equipment used on railway rolling stock, EN55022 Class B and EN50121-3-2 conducted and radiated EMI, and EN 61000 immunity standards.This converter is fully ruggedized and conformal coated, and meets IEC 61373 shock and vibration standards. It has around 90% efficiency, 4KV DC input to output isolation, inrush current limiting and reverse polarity protection at the input. Over-voltage, overload and short circuit protection are incorporated. Overtemperature protection is provided on units > 100W. Can be DIN rail mounted using the DRP-01A plate and a Meanwell DIN rail clip (DRP-04). NEW! The RSD-30 and RSD-60 series are now available with 3.3V output and 12VDC input options.

Also available are the RSD-150, RSD-200, RSD-300 and RSD-500 with 48V output option and Over Temperature Protection (OTP) with automatic recovery! The Meanwell RSP could replace units from Amtex, AbsoPulse, Martec Power, Polyamp, PowerBox, Railgroup, Snaptec such as; B110, BAP200R, BAP236R, DCW100R, RWY100, RWY150, RWY200, PSE100, PM80, PM150, PM240, PU300. Also could replace CABAC CCI rail products WR150E, WR150EQ, WR200E, MR150E and MR200E. Multiple units could be used to replace CABAC MR850E and 24WR500E. The entire RSD range provides operation up to 70°C... this is ideal for "hot" Australian conditions in industry, transportation and mining!

DDR range of DC-DC converters (above right) - NEW! DIN Rail mounted
The Meanwell DDR series of DC to DC converters provides wattages of 15W, 30W, 60W, 120W, 240W and 480W in output voltages of 3.3V, 5V, 12V (9V to 14V), 15V, 24V (24V to 28V) and 48V (48V to 56V). The 15 to 60W units provide 9..36V(G) or 18..75V(L) input. The 120W, 240W and 480W units are designed for railway applications and provide 9..14V(A), 17..33V(B), 34..67V(C), 68..154V(D) inputs. The 120W, 240W and 480W units also provide 150% peak current output. The 240W and 480W also provide remote on/off, a DC OK output and parallel operation up to 960W/1920W. The 480W unit provides 12V output. All DDR converters have a 3 year warranty.

NTS range of inverters (above left) - Designed for permanent installations with 100% up time!
The NEW Meanwell NTS range provide a True Sine Wave (TSW) DC to AC power inverter in 300, 450, 750, 1700, 2200, 3200 Watts with 200-240VAC~ output. These inverters can be used in continuous operation and at high temperatures (100% load at 40°C derated to 80% at 50°C and 40% at 70°C... 65°C for the NTS-300). Each inverter can be supplied in 12V, 24 or 48V DC input and each has a standby saving mode and adjustable output. i.e. 200, 220, 230, 240VAC and 50Hz or 60Hz. 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 (remember under full load, it could trip 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 of these products. 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.

These inverters can be used in continuous operation and at high temperatures (100% load at 40°C derated to 75% at 50°C and 40% at 60°C). Each inverter can be supplied in 12V, 24 or 48V DC input and each has a standby saving mode and adjustable output. i.e. 200, 220, 230, 240VAC and 50Hz or 60Hz. 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 locations. The TN-1500 and TN-3000 are great for solar charging in Mobile Homes!

All Mean-well inverters have a low battery voltage alarm and are protected against; reverse battery polarity, low battery voltage shut-down, over temperature, output over-load and short-circuit. The Meanwell TSW or Pure Sine Wave (PSW) inverters also have output abnormal (too high or too low) voltage protection and high battery voltage shutdown (with alarm). All have an on-off switch. All are fitted with 240VAC Australian power sockets (Type C or AU). Ex-factory models may be fitted with a Universal socket (Type UN).
