Product information

Description

The MEAN WELL DDR-120B-12 is an ultra-slim DC-DC industrial DIN-rail converter with a wide input range of 16.8–33.6 V DC and a single 12 V DC output rated at 10 A (120 W). The compact metal enclosure measures 32 mm (W) × 102 mm (D) × 125.2 mm (H) and the unit is RoHS compliant, suitable for space-constrained control cabinets and industrial power distribution.

Advantages

The DDR-120B-12 provides stable 12 V output with up to 10 A current in a very narrow housing designed for DIN-rail mounting. Its wide input range accommodates battery-backed or variable-voltage systems, while RoHS compliance ensures adherence to environmental regulations. The converter's compact footprint allows installation in dense equipment racks or small enclosures.

Suitable for

  • Industrial control cabinets and automation panels
  • Rail-mounted power distribution for PLCs and field devices
  • Battery-backed systems and voltage conversion in vehicles or machinery
  • OEM equipment where space is limited

Key specifications

  • Model: MEAN WELL DDR-120B-12 (MPN: DDR-120B-12, EAN: 4021087051033)
  • Input voltage: 16.8–33.6 V DC
  • Output: 12 V DC, 10 A (120 W)
  • Dimensions: 32 mm × 102 mm × 125.2 mm (W × D × H)
  • Mounting: DIN-rail
  • Compliance: RoHS
  • Pack quantity: 28 pieces

How to use

Mount the converter on a standard DIN rail inside the control cabinet. Connect the DC input to a suitable 16.8–33.6 V supply, observing polarity and using appropriately rated wiring and fuses. Connect the 12 V DC output to the load, ensuring the total current draw does not exceed 10 A. Allow adequate ventilation around the device and follow local electrical codes during installation.

Usage recommendations

For reliable operation, avoid exceeding the specified input range and output current; use short, properly rated cables and install protective fusing on the input side. When used in battery-backed systems, verify transient conditions and provide additional filtering if necessary.
