Din rail mounted AC self powered voltage control relays (no separate auxiliary supply required) for the combined monitoring of both over and under voltage levels. Available only in a din rail package with nominal voltages from 24VAC to 440VAC, an option adjustable time delay 0.1 to 10 secs “T” can be specified as a delay on tripping timer, (not possible on the YWROUV2).

YWROUV & YWR2OUV - SPCO and DPCO output devices respectively, with separate over and under voltage control levels set via potentiometers +20% and -30% against the nominal voltage. The output relay will be energised when the voltage is within the set points. Deviation above or below the setpoints will cause the output relay to deenergise, plus any optional time delay set. Total loss of supply will cause an immediate de-energisation. On the voltage returning to with the set levels +2% fixed hysteresis the output relay will re-energise. A green LED illuminated indicates a supply is present and a red LED illuminated indicates the output relay is in an energised state.

YWROUV2 - As above but with a separate relay output for over voltage and a separate relay output for under voltage, in a healthy state both relays are energised. R1 is designated as the over voltage relay and will de-energise if an over voltage level is reached. R2 is designated as the under voltage relay and will de-energise if an under voltage level is reached. The unit featured three LED indicators, green for a supply voltage present and individual red LED’s for R1 and R2, a de-energisation will cause the respective LED to extinguish.
