Customer Questions
What DIN rail sizes does the NDR-240-24 support?
The NDR-240-24 is designed to mount on TS-35/7.5 or TS-35/15 DIN rails. Its 63 mm depth profile is intended to help conserve space inside control cabinets.
Does this power supply work with both 115 VAC and 230 VAC mains?
Yes. The NDR-240-24 accepts a full-range AC input from 90 to 264 VAC at 47 to 63 Hz, so no manual voltage selection is required for compatible single-phase supplies within that range.
Can the output voltage be adjusted?
Yes. The output voltage is adjustable from 24 V to 28 V via the onboard trimmer, within the manufacturer's stated limits.
Does the NDR-240-24 require a cooling fan?
No. The unit is cooled by free air convection and does not include an internal fan. Adequate airflow clearance around the unit should be maintained as specified in the datasheet.
What certifications does the NDR-240-24 carry?
Manufacturer-verified certifications include UL508 (industrial control equipment), TUV BS EN/EN62368-1, and EAC TP TC 004. Agency approvals listed by Jameco include UL, CUL, TUV, CB, CE, EN, and EAC. The unit also conforms to EN61000-3-2 for harmonic current and meets EN61000-6-2 (EN50082-2) industrial immunity levels.
Customer Concerns
Will this supply handle inductive loads such as motors or solenoids without tripping?
The NDR-240-24 uses constant current mode for overload protection, which the manufacturer states is suitable for inductive or capacitive applications. Buyers should verify that the total load current and inrush characteristics fall within the manufacturer's rated limits and consult the datasheet for derating guidance.
Is this unit appropriate for continuous-duty industrial use?
The NDR-240-24 is rated for operation from -20 °C to +70 °C under free air convection and carries UL508 approval for industrial control equipment. Each unit undergoes a 100% full load burn-in test before shipment. Buyers should confirm that ambient temperature and airflow conditions at the installation site are consistent with the manufacturer's datasheet requirements.
How do I confirm this power supply will fit my enclosure?
The NDR-240-24 measures 4.93 inches wide by 4.47 inches tall by 2.48 inches deep (approximately 125 mm x 113.5 mm x 63 mm) and mounts on standard TS-35/7.5 or TS-35/15 DIN rails. Buyers should verify enclosure interior dimensions and DIN rail type before ordering. A 3D outline file (STEP in ZIP) is available on the product page for pre-installation fit checks.
