Frequently Asked Questions

Can the DDRH-60-48 supply 48V to PoE network switches in industrial Ethernet infrastructure powered from a high-voltage DC bus?

Yes. The DDRH-60-48 outputs 48V at 1.25A (60W) and accepts 150–1500VDC input, making it suitable for powering 48V PoE switches or injectors in industrial Ethernet networks where the source bus is a high-voltage DC system.

Is the DDRH-60-48 suitable for powering 48V DC fans, drives, or cooling systems in process control enclosures?

At 60W and 1.25A on a 48V rail, the DDRH-60-48 can supply 48V cooling fans and small variable-frequency drives used in process control enclosures that receive power from a high-voltage DC distribution bus.

Can the DDRH-60-48 be deployed in traction or rail environments with varying DC link voltages?

The 150–1500VDC input range covers standard rail traction voltages such as 600V and 750V DC. Combined with the –30°C to +80°C temperature rating, the DDRH-60-48 is appropriate for auxiliary power applications in rolling stock.

Does the adjustable output on the DDRH-60-48 allow fine-tuning for battery float charging at 48V?

The output voltage is adjustable up to +20% above the nominal 48V, allowing it to be set to approximately 57.6V, which can be used to float-charge 48V lead-acid battery banks within the 1.25A current limit.

Is the DDRH-60-48 appropriate for installation in outdoor roadside or utility cabinets?

The unit operates from –30°C to +80°C with a fanless 57mm slim-width design suited to compact outdoor enclosures. No IP rating is stated for the unit, so the external enclosure must provide rated environmental protection.

How does the DDRH-60-48 compare to the DDRH-60-12 and DDRH-60-24 in the same series?

All three share the 150–1500VDC input, 57mm slim-width form factor, fanless design, and +20% adjustable output. The DDRH-60-48 provides 48V at 1.25A (60W), versus 24V at 2.5A for the DDRH-60-24 and 12V at 5A for the DDRH-60-12.
