19UVPS-2120 Fireye Power Supply

Overview

The Fireye 19UVPS-2120 is a high-performance power supply module designed to provide the necessary electrical excitation for Fireye high-voltage ultraviolet (UV) and infrared (IR) scanners. It is specifically engineered to interface these scanners with 25SU3 series amplifiers. This rack-mounted module ensures stable voltage delivery, which is critical for maintaining accurate flame signals and preventing nuisance shutdowns in industrial burner management systems. The 19UVPS-2120 is built into a standard 3U 19-inch rack cassette, featuring a green LED on the front panel to indicate when power is active.

Features

• High Compatibility: Specifically designed for use with Fireye 45UV5, 45RM1, and 45RM2 series scanners.
• Multi-Scanner Support: Capable of powering up to six scanners simultaneously from a single module.
• Status Monitoring: Includes a front-panel green LED indicator to verify the main power source is applied.
• Ease of Installation: Designed as a plug-in module for standard 3U 19-inch industrial racks.
• Robust Design: Features a clear anodized aluminum cassette for durability in industrial environments.

Applications

The 19UVPS-2120 is primarily used in commercial and industrial combustion systems, including power generation, oil and gas refining, and chemical processing plants. It is required when using specific Fireye flame scanners (such as 45UV5-1000, 45UV5-1101, 45RM1, and 45RM2 models) in conjunction with 25SU3-2000 or -2100 series amplifiers. Its application is vital in systems requiring continuous-duty monitoring and high-voltage excitation for Geiger-Muller type UV sensors or specific IR electronics assemblies.
