Description
The TDK-Lambda DRB480-48-3-A0 is a powerful, efficient DIN rail-mounted 3-phase power supply designed for demanding industrial environments requiring 48VDC at 10A (480W) continuous output. It delivers exceptional performance in control systems, machinery automation, and process instrumentation where voltage stability and durability are critical.
This model operates from a wide 3-phase input range of 350–575VAC, ensuring compatibility across international installations. Its output is adjustable between 45 and 55VDC, with a high boost mode capacity of 576W (12A) for 600 seconds—ideal for loads with high inrush current or transient spikes.
The DRB480-48-3-A0 includes a full suite of protections, including constant current overload handling, latch-mode overvoltage shutdown, and thermal derating. Remote inhibit control and a DC-OK relay output enable integration into monitoring and control systems such as SCADA or industrial PLCs.
Designed for long-term reliability, it offers high efficiency (up to 94.6%), convection cooling, and compact DIN rail mounting in a 90mm-wide housing. The unit is certified to IEC/EN/UL/CSA 61010-1 and 62368-1, with CE and UKCA compliance for peace of mind in regulated environments.
