Frequently Asked Questions
Can I use the RQ-85B for a multi-output industrial controller that needs more 5V current than the 65W models?
Yes, this version raises the main 5V output to 7A and the total rated power to 80.7W. The product name also lists 12V, -5V, and -12V outputs, so it fits multi-rail control or interface hardware that needs more 5V capacity than lower-power siblings.
Is the RQ-85B suitable for embedded systems that use 5V logic and both positive and negative support rails?
It can be suitable because this quad output model includes 5V, 12V, -5V, and -12V outputs in one unit. With 5V rated at 7A and total power at 80.7W, it supports higher 5V demand than the 62.5W and 65W variants listed in the same family.
Can the RQ-85B be used in automation equipment exposed to vibration or limited cabinet space?
The listed dimensions are 159.0 x 97.0 x 38.0 mm and the weight is 0.6 kg, so it remains relatively low-profile for cabinet integration. The features also state miniature size and 5G vibration resistance, which is relevant for industrial and automation environments.
Is the RQ-85B appropriate for outdoor or high-temperature operating conditions?
Its operating temperature range is specified as -25 degrees C to +70 degrees C, so it is rated across a wide temperature span. No IP rating is given in the supplied specs, so the product data here does not verify protection against rain, dust ingress, or exposed outdoor conditions.
How does the RQ-85B differ from the other RQ series models listed here?
The supplied siblings are 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-85C at 82.5W and 5V 7A, RQ-85D at 84W and 5V 6A, RQ-125B at 120W and 5V 11A, RQ-125C at 122.5W and 5V 10A, and RQ-125D at 124W and 5V 8A. RQ-125ND appears in the sibling list as well, but no wattage or current values are supplied for that model.
