Frequently Asked Questions
Can the DDRH-30-15ST power industrial field devices such as transmitters or actuators that require 15 V?
Yes. The DDRH-30-15ST provides a constant 15 V output at up to 2 A (30 W), which covers many 15 V industrial field devices including signal conditioners, transmitters, and low-power actuators. Its screw terminal connections allow direct integration into terminal blocks common in industrial control panels.
Is the DDRH-30-15ST suitable for use in railway or transit applications with wide-ranging DC bus voltages?
The 150–1500 VDC ultra-wide input range makes the DDRH-30-15ST compatible with high-voltage DC buses that appear in railway traction auxiliaries and transit infrastructure, provided the input bus stays within 150–1500 VDC. The –40°C to +80°C operating range also accommodates the temperature extremes common in transit environments.
Will the DDRH-30-15ST work in an outdoor control cabinet without active cooling?
The DDRH-30-15ST uses a fanless design and is rated from –40°C to +80°C, so it does not require forced air cooling and can operate in sealed outdoor enclosures within that temperature range. There is no IP rating listed for the unit itself, so the enclosure must provide any needed environmental protection.
Can this converter supply 15 V power to embedded automation modules or HMI components mounted in a DIN rail panel?
While the DDRH-30-15ST is a screw terminal type rather than a DIN rail clip-in unit, its 135.0 × 70.0 × 32.0 mm footprint and screw terminals are suited for panel mounting alongside DIN rail components. It can power 15 V automation modules, HMI ancillary circuits, or gateway interfaces up to a combined 30 W load.
How does the screw terminal variant compare to the PCB and DIN rail variants in this 30 W 15 V family?
All three share 30 W output, 15 V / 2 A, 150–1500 VDC input, and –40°C to +80°C operating range. The DDRH-30-15ST (screw terminal) measures 135.0 × 70.0 × 32.0 mm and weighs 0.305 kg; the DDRH-30-15P (PCB mount) is smaller at 89.0 × 63.5 × 25.0 mm and 0.24 kg; the DDRH-30-15DR uses DIN rail mounting.
What certifications does the DDRH-30-15ST carry?
The DDRH-30-15ST holds CE and EAC certifications and carries a 3-year warranty.
