Pack of 5 SD15A12 isolated DC‑DC converters Key benefits Provides isolated 12 V rails to prevent ground loops and protect sensitive electronics by maintaining galvanic isolation between input and output. Regulated 12 V output keeps voltage stable under load for reliable operation of downstream devices. Efficient switching design reduces heat and enables a compact form factor for installations with limited space. Compact, robust package suitable for panel mounting and tight enclosures, simplifying integration into control cabinets and equipment racks. What it does Each SD15A12 unit is a DC‑DC converter that accepts 12 V DC input and delivers a regulated 12 V DC output. Rated at 15 W per unit with up to 1.25 A output current. Uses an isolated switching topology to provide galvanic isolation between input and output for safety and noise immunity. Compatibility and form factor Direct replacement where a stable, isolated 12 V supply is required. Compact package designed for panel mounting and cramped installations; robust construction for industrial environments. Suited to powering PLCs, sensors, microcontroller boards, embedded systems, small telecom/network devices, and similar loads that fit within the 15 W / 1.25 A limit.
