WM-138 Arcade Switching Power Supply (5V / 12V / 24V)
An affordable, multi-output DC power supply designed for arcade machines, JAMMA/MAME cabinets, and DIY coin-op projects. Built as a compact switch-mode power supply (SMPS) with universal AC input and multiple DC rails, it delivers clean, stable power for game PCBs, lights, sound amps, displays, solenoids, and accessories.
Features
- Universal AC input: 100–260 V AC at 50/60 Hz — works worldwide without a voltage switch.
- Multiple DC outputs:
• +5 V DC — high-current supply for game logic and digital electronics
• +12 V DC — powers fans, displays, audio amps, and other peripherals
• +24 V DC — ideal for marquee lights, solenoids, knockers, sequencers, and other higher-voltage accessories commonly found in arcade and redemption machines. - High efficiency & low noise: Switching topology with built-in EMI/RFI filtering keeps ripple and noise low, helping video, audio, and digital circuits run cleanly.
- Compact, rugged construction: Enclosed metal housing with screw or terminal block connections simplifies installation in upright or cocktail cabinets.
Specifications
- AC Input: 100–260 V AC 2.5 A, 50/60 Hz
- +5 V DC Output: High-current rail (~16 A)
- +12 V DC Output: Mid-range current (~6 A)
- +24 V DC Output: Auxiliary rail for marquee, lighting, and solenoids (~2 A)
Application Scenarios
- Powering JAMMA or MAME arcade PCBs reliably.
- Driving lighting systems, marquees, or accessory modules that require 24 V.
- Replacing aging linear supplies in classic cabinets with a compact SMPS solution.
- Bench power for hobbyist electronics projects needing multiple DC voltages.
