PS-DA0408-017
by Beckhoff
The Beckhoff PS-DA0408-017 from the PS Power Supplies series is a specialized LCD Inverter Module designed for industrial automation applications. This module provides a lamp startup voltage of approximately 1,570 V RMS and delivers a stable input voltage of 10.8 V DC for reliable backlighting of LCD panels. With a lamp current specification of 4 x 7.0 mA RMS, it ensures consistent brightness and clarity across four independent outputs. The primary function of the PS-DA0408-017 is to convert low-voltage DC power into the high-voltage AC signal required to drive fluorescent backlight lamps in displays used in harsh industrial environments.
In terms of technical details, the PS-DA0408-017 supports an output power of approximately 18 W spread evenly over its quad outputs, enabling high efficiency and uniform illumination. The module operates within an operating temperature range of -10°C to +60°C, ensuring stable performance under varying thermal conditions. It also features a wide storage temperature range of -20°C to +85°C, accommodating rigorous shipping and storage requirements. The PS-DA0408-017 maintains operation in environments with up to 95% RH (non-condensing) humidity, demonstrating robustness against moisture without producing condensate-related failures.
Beyond its core specifications, the PS-DA0408-017 excels in compatibility and durability for industrial control systems. Its ability to function reliably over a broad temperature spectrum and high humidity levels underscores its suitability for factory floors and outdoor enclosures. The inverter’s high-efficiency conversion minimizes power loss and heat generation, contributing to overall system longevity. Although no specific industry certifications are listed, Beckhoff’s reputation in industrial automation guarantees strict quality control during manufacturing. By integrating the PS-DA0408-017 into LCD backlighting setups, engineers benefit from consistent lamp ignition, reduced maintenance intervals, and enhanced display performance—key advantages for critical industrial monitoring and control applications.
