The phrase "a relatively low voltage" is correct and usable in written English.
It can be used in contexts discussing electrical systems, electronics, or any situation where voltage levels are being compared.
Example: "The circuit operates efficiently at a relatively low voltage, minimizing energy consumption."
Alternatives: "a comparatively low voltage" or "a modest voltage level."
A symmetrical AC power supply, operating at a relatively low voltage (less than 250 V), was used in the EPP treatment.
The structure and properties of anodic films formed in a relatively low voltage range in ammonium adipate solution have been investigated focusing on the effect of formation voltage.
It was shown that 10 min anodizing is sufficient to grow a protective layer by PEO under galvanostatic conditions (10 mA cm− 2), with a relatively low voltage (50 to 70 V).
As a result, the system can be operated under a relatively low voltage.
The X-ray tube can be operated under a relatively low voltage compared with other works [20 22].
A relatively low voltage applied to a metal oxide film sandwiched between two electrode layers sends lithium ions "shuttling between the two electrodes," Whitney explains.
The electrodes are recharged by draining the saltwater, replacing it with freshwater, and applying a relatively low-voltage electrical current, which draws the ions back out of the electrodes.
Electric arc, continuous, high-density electric current between two separated conductors in a gas or vapour with a relatively low potential difference, or voltage, across the conductors.
Prior to the onset of spraying, this system is highly analogous to the type of system discussed in this paper, except that the bias supply is set to a high voltage rather than the relatively low voltage needed to cancel.
But because of the relatively low voltage and the drop in the line, a DC generator could reliably serve customers only within a radius of a mile or so.
