MEAN WELL RS-150-24 Power Supply Unit 156 W Metallic 115 - 230 V 47 - 63 Hz

The MEAN WELL RS-150-24 is a reliable 156 W power supply unit designed for efficient electrical conversion. Operating with an AC input voltage of 115 to 230 V at 47 to 63 Hz, this device is housed in a durable metallic enclosure built to withstand demanding environments. It features a high mean time between failures of 244000 hours, a voltage tolerance of 1 percent, and comprehensive built-in protections against overvoltage, overload, and short circuits to ensure stable, long-term performance for various industrial and electronic applications.

Advantages

This power supply unit offers exceptional reliability and longevity through the use of 105 degree Celsius long life electrolytic capacitors and a 100 percent full load burn-in test during manufacturing. Cooling is efficiently managed by free air convection, eliminating the need for noisy internal fans. The unit supports high operating temperatures up to 70 degrees Celsius, withstands a 300 VAC surge input for 5 seconds, and is built to resist mechanical stress with a 5G vibration test rating. Additionally, a clear LED indicator confirms when the power is active.

Suitable for

• Industrial automation systems
• Electronic equipment requiring stable 24V power
• Control panels and machinery
• Indoor electrical installations

When it may not be suitable

This power supply unit is not designed for outdoor use without an appropriate weatherproof enclosure, as it relies on free air convection and lacks water resistance. It is also unsuitable for applications requiring adjustable output voltage or redundant power configurations.

Key specifications

• Power output: 156 W
• Output voltage: 24 V
• Input voltage range: 115 to 230 V AC
• Input frequency: 47 to 63 Hz
• Cooling type: Free air convection
• Operating temperature range: -25 to 70 °C
• Built-in protections: Short circuit, overload, overvoltage

How to use

Mount the metallic enclosure securely in a well-ventilated area to allow proper free air convection cooling. Connect the appropriate AC input wires corresponding to the 115 to 230 V range to the designated input terminals, ensuring the power is switched off during installation. Connect your 24V load to the output terminals with correct polarity. Verify all connections before turning on the power source. The LED indicator will light up to confirm successful operation.

What to consider before purchase

• Verify that the 156 W power output and 24 V specifications match your electrical load requirements.
• Ensure adequate ventilation space around the metallic enclosure for free air convection.
• Check the physical dimensions and mounting requirements for your specific installation space.
• Confirm that the operating environment stays within the -25 to 70 °C temperature range.

Usage recommendations

Always disconnect the main power source before performing any wiring or maintenance tasks. Ensure that the installation site provides sufficient airflow for free air convection to prevent thermal accumulation and maintain the long operational life of the unit.
