Description
The TDK-Lambda DRB960-48-3-A0 is a rugged and reliable DIN rail-mounted 3-phase power supply designed to deliver 960W at 48VDC / 20A for high-power industrial and automation systems. Optimised for performance and long service life, it’s ideal for applications such as factory automation, machine control, and industrial instrumentation.
Operating from a wide 3-phase input range (350–575VAC), the DRB960-48-3-A0 ensures stable power delivery in demanding global environments. Its output voltage is adjustable from 45 to 55VDC, and it supports boost mode output up to 1152W (24A) for 600 seconds—perfect for capacitive or transient-heavy loads.
The unit integrates advanced features including constant current overload protection, latch-mode overvoltage shutdown, a DC-OK relay contact, and remote inhibit input—making it highly adaptable to modern industrial control systems. With high energy efficiency up to 95.2%, it reduces energy waste and heat build-up, helping to prolong component life.
Certified to IEC/EN/UL/CSA 61010-1 and 62368-1 and compliant with CE and UKCA standards, the DRB960-48-3-A0 is built to operate in harsh conditions, up to +70°C without derating below +55°C. It comes in a compact 110mm-wide housing, ideal for space-constrained DIN rail installations.
