Frequently Asked Questions
Can I use the RQ-125C for an industrial controller that needs a 5V logic rail plus +/-15V analog rails?
Yes. The RQ-125C is a quad output supply with a 5V main output rated at 10A and a total power rating of 122.5W. That combination fits control and analog systems that need a regulated 5V rail alongside 15V and -15V outputs from one power supply.
Is the RQ-125C suitable for embedded test equipment with both digital and instrumentation sections?
It can be a good fit when the equipment needs 5V for digital circuitry and +/-15V rails for analog stages. The supply provides constant voltage output, up to 10A on the 5V rail, and 122.5W total in a 199.0 x 98.0 x 38.0 mm package. Its compact size is useful where panel space is limited.
Can the RQ-125C power a mixed-signal automation assembly from one AC input?
Yes, if the assembly is built around 5V logic and also requires 15V and -15V rails. The RQ-125C accepts 88-264VAC input and combines the outputs in one 0.7 kg unit. That makes it practical for compact automation or measurement enclosures using a universal AC input range.
Is the RQ-125C appropriate for indoor control cabinets or harsher factory conditions?
The operating temperature range is -25°C to +70°C, and the unit is specified to withstand 5G vibration. That supports use in demanding indoor industrial environments. No IP rating is listed in the provided specs, so the product data does not establish suitability for direct outdoor exposure.
How does the RQ-125C compare with other Mean Well RQ series models?
Within the listed siblings, the RQ-125C is rated at 122.5W with a 5V main output at 10A. Other models are RQ-125B at 120W and 5V 11A, RQ-125D at 124W and 5V 8A, 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 as a sibling, but no specs were provided for it here.
