Power supply unit electro base LEI MH30-3120250-C5 30W 12V DC 2.5A

The power supply unit electro base LEI MH30-3120250-C5 30W 12V DC 2.5A is a compact fixed-output transformer designed to provide stable 12 V DC power for small electronic systems. With a rated output of 30 W and maximum current of 2.5 A, it supports continuous operation of LED lighting strips, CCTV cameras, access control modules and other low-voltage devices that require a consistent DC supply. The metal enclosure and simple wiring terminals make it suitable for wall- or cabinet-mounted installations where space is limited.

Advantages

This 12 V DC power supply offers regulated output to reduce voltage fluctuations and protect connected devices. Its compact footprint and low-profile housing simplify integration into control panels and junction boxes. Built for continuous duty, the unit provides reliable performance for both permanent and temporary installations. The fixed-voltage design eliminates the need for adjustment and reduces installation complexity.

Suitable for

• LED strips and low-voltage lighting
• CCTV cameras and video surveillance systems
• Access control panels, electric locks and readers
• Small appliances and electronic modules requiring 12 V DC
• Embedded systems and prototype development benches

Key specifications

• Output voltage: 12 V DC
• Maximum output power: 30 W
• Maximum output current: 2.5 A
• Fixed regulated output suitable for continuous operation
• Compact metal enclosure for mounting in cabinets or on walls
• Terminal block connections for input and output wiring

How to use

Install the power supply on a stable surface inside an appropriate enclosure or mounting location, ensuring adequate ventilation and clearance from heat sources. Connect the AC input according to local electrical codes, observing correct live, neutral and earth wiring. Attach the 12 V DC output to the load, observing correct polarity. Verify the total connected load does not exceed 2.5 A and avoid prolonged operation at the maximum rating when possible. After wiring, power on and confirm stable 12 V output with a suitable meter before connecting sensitive equipment.

Usage recommendations

For reliable long-term operation, place the unit in a ventilated area and protect it from direct moisture and dust. Use appropriately rated fuses or circuit breakers on the AC input and consider surge protection for installations in areas with unstable mains voltage. When powering multiple devices, calculate cumulative current to maintain margin below the 2.5 A peak rating.
