Q: What is necessary to detect undervoltages when using the same power supply for the input voltage and the control
A: The NO contact of the output relay is used for undervoltage detection. Even if the control voltage drops to 85% of
Q: Will the SDV be damaged if the input setting (AC/DC) is incorrect. If not, what will happen?
A: The SDV will not be damaged, but the operating value and reset value will not be accurate. These values will be
Q: Can the negative pole of a DC voltage be input to the SDV?
A: Yes. An absolute rectifier circuit is used in the SDV-F to enable negative pole input. The SDV-FL has a polarity
Q: Are models available with special processing for high-temperature, high-humidity?
A: Yes. The model numbers for special processing for high-temperature, high-humidity end in “TC.”
Q: Is instantaneous detection faster than 0.5 s possible?
A: Use the S87A Power Interruption Detector for instantaneous detection (10 ms or 20 ms).

be used for the dual-function SDV-D even if the intermediate voltage of dead band is set to 0. Negative inputs can-
not be used for the SDV-D.
