Every unit undergoes 100% full-load burn-in testing to ensure long-term reliability, and Leyu provides customization services to adapt the power supply to specific application needs, such as modified connectors or voltage tweaks.

Key Features

Ultra-Low Ripple & Noise for Clean Power

The 25W MS-25 AC to DC Single Output Power Supply maintains minimal ripple and noise, with a maximum of 100mVp-p (and 50mVp-p for the 5V model). This low interference ensures clean power delivery, which is critical for sensitive electronics like communication modules, precision sensors, or audio equipment—preventing signal distortion or performance glitches.

Flexible Voltage Tuning & Tight Tolerance

It offers a voltage adjustment range of ±10% (+10%, -5% for the 5V model), allowing users to fine-tune output voltage to match their equipment’s exact needs. Additionally, it features tight voltage tolerance (±1% for 12V/15V/24V models; ±2% for 5V) and line stability of ±0.5%, ensuring consistent output even when input voltage fluctuates (e.g., during peak power hours).

Reliable Line & Load Stability

With load stability of ±0.5% (±1% for 5V), the power supply keeps output voltage steady as the load varies from 0% to 100%. This is essential for devices with dynamic power demands, such as LED drivers or industrial PLCs (Programmable Logic Controllers), avoiding voltage drops that could cause equipment malfunctions or data loss.

Fast Startup & Extended Hold-Up Time

The 25W MS-25 features a rapid startup time of 300ms (230VAC) and 800ms (115VAC), enabling connected devices to power up quickly. It also provides a hold-up time of 90ms (230VAC) and 12ms (115VAC), maintaining power during short input interruptions—critical for preventing system shutdowns in applications like routers or industrial controls.

Safe Inrush Current & Durable Components

Cold-start inrush current is limited to 30A (230VAC) and 15A (115VAC), protecting both the power supply and the input grid from sudden surges. It also uses 105°C high-temperature output capacitors, ensuring durability even in harsh operating environments. A built-in EMI filter complies with CLSPR22 (EN55022) and IEC801-2, 3, 4 standards, reducing electromagnetic interference and meeting global regulatory requirements.

Comprehensive Over-Load Protection

The power supply includes over-load protection that triggers at 105%~150% of the rated load. It uses a hiccup shutdown mechanism with auto-recovery—resuming operation automatically once the overload is resolved—eliminating the need for manual reset and maximizing system uptime.

Practical Applications

LED Drivers

The 25W MS-25 AC to DC Single Output Power Supply is an ideal match for LED drivers, especially those requiring 24V DC output. Its low ripple and noise (≤100mVp-p) prevent LED flicker, while its high efficiency (up to 80%) reduces energy consumption and heat buildup—extending the lifespan of both the driver and LEDs. Its compact size (85*58*38mm) fits easily into residential downlights, commercial display panels, or outdoor LED signage.

Industrial Control Systems

In industrial settings, the power supply powers PLCs, sensors, and small automation devices. Its wide operating temperature range of -10℃~+60℃ (refer to the output derating curve for extreme conditions) and vibration resistance (10~500Hz, 2G for 10 minutes per cycle, 60 minutes per axis) make it suitable for factory floors or harsh outdoor industrial environments. The ±0.5% load stability ensures control signals remain accurate, avoiding production delays.

Consumer Electronics

For consumer devices like small home appliances, portable audio equipment, or smart home sensors, the 25W MS-25 offers a space-efficient and energy-saving solution. Its global input range (85~132VAC/170~264VAC) works in any country, and its lightweight design (0.2Kg) integrates easily into compact product enclosures. Built-in safety features (e.g., over-load protection) also enhance user safety.

Communication Devices

Communication systems—such as routers, modems, or small base stations—rely on consistent power to maintain signal integrity. The 25W MS-25’s low EMI (compliant with IEC555-2) prevents signal interference, while its hold-up time (90ms at 230VAC) ensures uninterrupted operation during brief power outages. This reliability minimizes communication downtime, making it a top choice for telecom applications.
