Description

The TDK-Lambda DRB960-24-3-A0 is a high-capacity DIN rail-mounted 3-phase power supply delivering a robust 960W output at 24VDC / 40A, engineered for the most demanding industrial and automation applications. This model is built to support large control systems, high-power loads, and critical infrastructure requiring uncompromising performance and reliability.

This model operates from a wide 3-phase input range of 350–575VAC, and support for peak loads up to 1152W (48A) for 600 seconds, the DRB960-24-3-A0 ensures consistent voltage stability and startup capability for capacitive or motor loads. The output is adjustable from 22.5V to 28.5VDC, accommodating diverse system requirements.

Advanced protection features include constant current overload handling, latch-mode overvoltage protection, remote inhibit control, and a DC-OK relay output for seamless system diagnostics and remote status monitoring. High efficiency of up to 95.1% minimises energy waste and thermal stress, extending the service life of both the PSU and connected components.

Designed for industrial environments, the DRB960-24-3-A0 operates reliably up to +70°C with no derating required below +55°C. It is housed in a 110mm-wide enclosure suitable for standard TS35 DIN rail mounting and is certified to IEC/EN/UL/CSA 61010-1 and 62368-1 standards with CE and UKCA compliance.

Features and Benefits – TDK-Lambda DRB960-24-3-A0
