Power Supply, AC/DC, DIN Rail, Economical Ultra Slim Industrial, 24VDC, 20A, 480W

Choose a power supply based on your equipment’s required DC output voltage, total current consumption, power rating, AC input voltage and operating environment. Allow additional capacity for startup surges and future system expansion. Also consider temperature ratings, available cabinet space, and any required safety certifications.

A DIN Rail power supply converts AC input voltage into regulated DC power for industrial automation equipment, including PLCs, HMIs, sensors, relays and other control components. It mounts directly onto a standard DIN rail inside an Electrical control cabinet.

The DC OK signal indicates whether the power supply’s DC output is operating within its specified voltage range.

Depending on the model, this indication may be provided through the LED, relay contact, or a communication interface. It can be connected to a PLC or monitoring system to help identify power supply faults or abnormal output conditions.

This feature is especially useful in industrial applications where monitoring power availability is important for system reliability.

Rated power is the continuous amount of power a power supply is designed to deliver under specified operating conditions. Peak power is the higher output level that a power supply can temporarily provide to accommodate short-duration increases in demand.

For example, a 240W power supply with 200% peak power capability may temporarily deliver up to 480W under the manufacturer’s specified conditions. This can be useful when powering equipment with high startup currents, such as motors, Solenoids, and capacitive loads.

Peak Power is not intended for continuous operation.

Our DIN Rail power supplies include built-in protection features designed to help protect the power supply and connected equipment from electrical faults. Depending on the model, these may include:

• Short-Circuit Protection: Helps prevent damage when the output terminals are shorted.
• Overload Protection: Limits output current or shuts down the supply when connected equipment draws excessive power.
• Overvoltage Protection: Helps prevent excessive output voltage from damaging connected devices.
• Overtemperature Protection: Protects the power supply if internal temperatures exceed safe operating limits.

These protections help improve system reliability and reduce the risk of equipment damage.

Single-phase power supplies operate from a single-phase AC input, commonly used in smaller industrial control panels and automation systems. Three-phase power supplies accept three-phase AC input, making them suitable for larger industrial installations with higher power requirements.

By multiplying Volts (V) with Amps (A), you can figure out Watts (A). You can rearrange the basic electrical power equation depending on what you need to solve:

Watts = Volts x Amps

Amps = Watts ÷ Volts

Volts = Watts ÷ Amps

Products:

Yes. Some power supplies require output derating at elevated temperatures. Always compare the expected enclosure temperature with the manufacturer’s derating specifications before selecting the supply.

When sizing a power supply, consider the maximum expected ambient temperature inside the enclosure, not just the room temperature. In high-temperature environments, you may need to select a power supply with a higher wattage rating to ensure reliable operation and prevent overheating.

Higher voltage allows electrical power to be delivered using less current. According to the power formula (Watts = Volts x Amps), increasing voltage reduces the amount of current needed to deliver the same amount of power. Lower current also reduces heat generation, voltage drop, and power losses in wiring, making higher-voltage systems more efficient for transmitting power over longer distances.
