EAE PS640 KNX Power Supply 640mA (SMP PS640)

Description

Introduction

The EAE PS640 Power Supply is a dedicated 640 mA system power unit designed specifically for KNX building automation networks. Engineered to deliver reliable bus voltage, Output 1 provides standard 30V DC (SELV) KNX bus power complete with an integrated choke to separate DC power from data communications. This ensures clean, stable power delivery across all connected bus devices on the line. This device is part of our KNX system devices range.

To offer extended functionality within distribution boards, the unit also features Output 2, a separate 30V DC (SELV) output designed for auxiliary device power requirements. Built with essential short-circuit and overload protection, along with clear diagnostic LEDs and a manual reset button, the EAE PS640 ensures high operational reliability for KNX installations.

Key Features

• 640 mA total current output capacity
• Output 1: 30V DC (SELV) KNX bus line power with integrated choke
• Output 2: 30V DC (SELV) auxiliary voltage output
• Wide AC input voltage range of 150-275V AC at 50/60Hz
• Comprehensive short-circuit and overload protection
• Diagnostic LED indicators for Power, Overload, and Reset status
• On-device manual Reset button

Benefits

• Provides 640 mA total output current capacity to power standard KNX bus lines reliably.
• Includes an integrated choke on Output 1 for direct connection to the KNX bus without requiring an external choke.
• Features a dedicated 30V DC auxiliary output (Output 2) for supplementary system voltage needs.
• Enhances operational uptime with built-in short-circuit and overload protection across its outputs.
• Simplifies diagnostics and monitoring via front panel LED indicators for Power, Overload, and Reset status.
• Allows manual system reset directly on the device using the integrated Reset button.
