Please message me for out-of-stock units as these can often be obtained ex-factory within 5 working days at no additional cost! Note, any item with ONE(1) in stock comes ex-factory (please message me if you require more than one). The HA8572 DIN rail (175mm length) is only available with a power supply purchase! For a video of the DDR-120... click here.

DIN rail mounted DC to DC converter from Meanwell. For home, industry, transport, railway, ITE, telecom etc. Contant current output, with up to 150% peak current output, makes it ideal for driving motors, lamps and highly capacitive devices (e.g LED drivers or other DC-DC converters). All units provide short circuit, overload (OLP), over voltage (OVP) and input reverse polarity protection. They also incorporate low input voltage shutdown. The 240W and 480W units include Over Temperature Protection (OTP). All units have adjustable pot outputs and can be set to 13.8V, 27.6V and 55.2V if necessary. The 120W unit can also be set down to 9V output. The Battery Backup example pictures, shows a UPS (Uninterruptible Power Supply) which drives multiple DDR units for simultaneous 12V, 24V and 48V outputs.

The DDR120 series
provides 12V@10A, 24V@5A or 48V@2.5A (A type = 12V@8.3A, 24V@4.2A or 48V@2.1A) with LOW ripple & noise 50mVp-p. They operate from 9-18VDC (type A = 12V battery), 17-33VDC (B = 24V battery), 34-67V (C = 48V battery), 68-154V (D = 96V battery or 120VDC).
Weighs 0.5kg, Size 30x125x113mm.

The DDR240 series
provides 24V@10A or 48V@5A outputs. For higher current output, up to 4 units can be connected in parallel (providing up to 40A@24V or 20A@48V). They operate from 17-33VDC (type B = 24V battery), 34-67V (C = 48V battery), 68-154V (D = 96V battery or 120VDC).
Weighs 0.75kg, Size 40x125x113mm. Features: Over Temperature Protection (OTP), Remote ON/OFF, DC OK relay output, parallel operation of up to 4 units or 960 Watts.

The DDR480 series
provides 12V@33.4A, 24V@20A or 48V@10A outputs. For higher current output, up to 4 units can be connected in parallel (providing up to 132A@12V, 80A@24V or 40A@48V). They operate from 17-33VDC (type B = 24V battery), 34-67V (C = 48V battery), 68-154V (D = 96V battery or 120VDC).
Weighs 1.375kg, Size 86x125x129mm. Features: Over Temperature Protection (OTP), Remote ON/OFF, DC OK relay output, parallel operation of up to 4 units or 1920 Watts.

All Meanwell products have a 2 to 7 year warranty. MEAN WELL Enterprises Co., is a Taiwan based company started in 1982 with strong ties worldwide (some well-known companies re-badge their products) and they provide excellent support and backup. Meanwell is a TQM (Total Quality Management) company and is ISO9001 certified. In 2017, the 2-year return rate was 1 in 6600. Meanwell power supplies are extremely reliable in our experience with only one unit DOA (Dead On Arrival) that was replaced and three returned during the warranty period in the 10+ years we have been selling... one power supply had been installed in a control box outdoors (for advertising) and had been attacked by a nest of ants! Meanwell now offers a range of fully sealed units (IP65 and IP67 rated)... please ask us for advice for outdoor and hazardous environments. For a company video - click here.

Some "on-the-web" comments... 1. "I have hundreds of 600 Watt 24V Meanwells running in the field and probably another 100+ 350Watt 5V running in the field and they are the most reliable piece of equipment compared to everything else. I've -never- replaced one in over 11 years, but I have replaced a lot of cruddy circuit boards designed or assembled by the less technically inclined (companies).", 2. "But in the end I've learnt a lesson here and that is spend the extra cash and buy some quality power supplies like the meanwell brand or else you could be in for a very frustrating time but I don't have the budget for that this year so I'll have to deal with what I have (sad face)". 3. Need a decent power supply... I can recommend mean well supplies. They are low end industrial supplies but are good quality, much better than no-name chinese supplies you can get from ebay etc.. I use mean well in lots of equipment and have had very few failures in thousands of hours of run time.

We also provide a download (or CDROM on request) with the documentation in PDF format and other information on Meanwell products.
