Test conditions and notes5
  1. 1. All parameters NOT specially mentioned are measured at 230VAC input, rated load and 25℃ of ambient temperature.
  2. 2. Ripple & noise are measured at 20MHz of bandwidth by using a 12" twisted pair-wire terminated with a 0.1uf & 47uf parallel capacitor.
  3. 3. Tolerance : includes set up tolerance, line regulation and load regulation.
  4. 4. The power supply is considered a component which will be installed into a final equipment. The final equipment must be re-confirmed that it still meets EMC directives.
  5. 5. The ambient temperature derating of 3.5℃/1000m with fanless models and of 5℃/1000m with fan models for operating altitude higher than 2000m(6500ft).

FAQ

Can I use the DR-4505 in a PLC or industrial automation control panel that needs 5V DC?

Yes. The DR-4505 provides 5V DC at up to 5A with 25W rated output, which fits 5V loads inside industrial automation or PLC control panels when the total load stays within those ratings. Its DIN rail form factor and 93 × 78 × 67 mm size also suit cabinet-based installations.

Is the DR-4505 suitable for 5V devices inside a building management control cabinet?

It can be used where the control cabinet requires a 5V DC supply up to 5A. The 25W rating makes it appropriate for low-voltage building management electronics that are specified for 5V operation. Buyers should match the cabinet load to the unit's 5V, 5A, and 25W limits.

Can this 5V DIN rail power supply be used for compact control enclosures with limited space?

Yes. The DR-4505 is a DIN rail power supply with a relatively compact body at 93 × 78 × 67 mm and a weight of 0.31 kg. That makes it practical for compact control enclosures where a DIN rail-mounted supply is preferred over a larger chassis-style unit.

Is the DR-4505 intended for use inside an enclosure or control cabinet?

Yes, that is the typical fit for this type of DIN rail power supply. The provided specs show a DIN rail format and an operating temperature range of -10°C to +50°C, which aligns with indoor control cabinet or enclosure use. The listed data does not indicate an outdoor or washdown-rated housing.

How does the DR-4505 compare with the other 45W DR series models?

Within the DR-45 series, DR-4505 is rated 25W at 5V and 5A, DR-4512 is 42W at 12V and 3.5A, DR-4515 is 42W at 15V and 2.8A, and DR-4524 is 48W at 24V and 2A. The main difference is the output voltage and corresponding output current and power. Buyers usually choose among them based on the DC bus voltage their equipment requires.
