Brief Introduction to BECKWITH ELECTRIC M-3425A Power Supply
1. Product Description
The BECKWITH ELECTRIC M-3425A is a stable, industrial-grade power supply designed mainly for electrical protection and control devices. It provides reliable DC power to equipment like relays, meters, and automation controllers in power systems (such as substations, power distribution networks) and industrial facilities.
With a compact design, it’s easy to install in control panels and built to handle common industrial conditions (like voltage fluctuations or mild vibration). It ensures connected devices get steady power—preventing shutdowns or malfunctions caused by unstable electricity, which is key for safe and continuous operation of power-related systems.
2. Technical Specifications
- Input Voltage: 120/240 V AC (dual-range, compatible with common industrial AC power sources)
- Output Voltage: 24 V DC (stable output for most low-voltage control devices)
- Output Current: 5 A (can power multiple small to medium-sized devices at the same time)
- Efficiency: ≥85% (reduces energy waste during power conversion)
- Operating Temperature: 0°C to +55°C (works in typical indoor industrial environments)
- Dimensions: Compact size (approx. 150 mm × 100 mm × 60 mm) for panel mounting
- Protection Features: Overload protection (shuts down temporarily if current exceeds limit) and short-circuit protection (prevents damage from wiring errors)
- Compliance: Meets industrial safety standards (e.g., UL, CSA) for reliable use in power systems
3. System Introduction
The M-3425A is part of BECKWITH ELECTRIC’s “Industrial Power Supply Series”—a lineup focused on powering critical electrical protection and control systems. These systems are widely used in power grids, substations, and industrial plants to monitor, protect, and control electrical equipment (like transformers, circuit breakers).
In the system, the M-3425A acts as a “power source hub”: it takes AC power from the grid, converts it to stable DC power, and supplies it to core control devices. Without a reliable power supply like this, protection devices (e.g., fault detectors) might fail to work—leading to potential electrical accidents or system downtime. This series is trusted for its durability, making it a common choice in power and industrial sectors.
