Purchase now: Weidmüller PRO TOP3 960W Power Supply
Purchase now: Atlantech Drives provides you the Weidmüller 2781950000 (Model: PRO TOP3 960W 24V 40A), the ultimate **3-Phase Power Supply** from the high-end **PROtop** series. Delivering a massive **40 Amps** at **24 V DC** (960 Watts), this unit is designed for heavy industrial automation where reliability is non-negotiable. It accepts a wide 3-phase input voltage (3 x 320…575 V AC) and offers an industry-leading efficiency of up to **95.3%**, resulting in minimal heat loss and energy savings.
Technical Specifications and DCL Peak Power
The hallmark of the PROtop series is the **DCL (Dynamic Current Limiting)** technology. This feature allows the power supply to deliver huge pulse reserves (up to 600% current for 15ms) to reliably trip downstream circuit breakers in the event of a short circuit, preventing system-wide voltage dips. It also features a **Static Boost** of 130% continuously at up to 40°C. The metal housing is extremely compact for a 1kW unit, saving valuable DIN rail space.

Expert Tips: 2-Phase Operation
Lost a phase? No problem. Expert Tip: The 2781950000 is robust enough to operate continuously on only **2 phases** (e.g., if one fuse blows upstream) provided you derate the output power slightly (check manual, typically 50-75% load is sustainable). This «Phase Loss Immunity» prevents immediate machine stoppage, giving maintenance teams time to react to the mains fault without a hard crash.
Frequently Asked Questions (FAQs)
Q: Can I connect it to a DC bus?
A: Yes, PROtop 3-phase units generally accept high voltage DC input (e.g., 450…800 V DC) on the input terminals, making them suitable for DC grid applications.
Q: How do I get IO-Link data?
A: You must purchase the separate clip-on communication module (e.g., PRO COM IO-LINK) which snaps onto the front face of the power supply to transmit voltage, current, and temperature data to the PLC.
