Frequently Asked Questions
Can I use the RQ-125D in an automation system that needs 5V logic plus 24V and +/-12V rails?
Yes. The RQ-125D is a quad output constant voltage power supply with a 5V main output rated at 8A and a total power rating of 124W. Its output set is suited to systems that combine low-voltage logic with 24V and -12V or 12V support rails in one enclosure.
Is the RQ-125D a good choice for industrial test or data-acquisition equipment with multiple voltage rails?
It is designed for multi-rail equipment rather than a single-output load. The 5V rail is rated for 8A, while the product also includes 24V, 12V, and -12V outputs under a 124W total power rating. That makes it relevant for mixed digital and control-oriented equipment that needs several DC rails from one AC-fed supply.
Can the RQ-125D support embedded control hardware in a compact cabinet?
It can when the hardware needs a 5V logic rail and additional 24V and +/-12V rails. The housing measures 199.0 x 98.0 x 38.0 mm and weighs 0.7 kg, so it fits applications where space is tighter than larger industrial power supplies. The 88-264VAC input range also supports broad AC input conditions.
Is the RQ-125D meant for indoor industrial environments or outdoor exposure?
The listed operating temperature range is -25°C to +70°C, and the unit is specified to withstand 5G vibration. Those specs support use in industrial indoor environments with temperature variation and vibration. No IP rating is provided, so the available data does not confirm outdoor or washdown suitability.
What are the main differences between the RQ-125D and the other RQ series siblings listed here?
The RQ-125D is rated at 124W with a 5V main output at 8A. The listed siblings are RQ-125B at 120W and 5V 11A, RQ-125C at 122.5W and 5V 10A, RQ-50B at 45.5W and 5V 5A, RQ-50C at 50W and 5V 5A, RQ-50D at 53.4W and 5V 3A, RQ-65B at 62.5W and 5V 6A, RQ-65C at 65W and 5V 5A, RQ-65D at 68W and 5V 4A, RQ-85B at 80.7W and 5V 7A, RQ-85C at 82.5W and 5V 7A, and RQ-85D at 84W and 5V 6A. RQ-125ND is listed but its specs were not included in the source data.
