SELF POWERED DC VOLTAGE CONTROL RELAYS

Din rail mounted or 8/11 pin plug in DC self powered voltage control relays (no separate auxiliary supply required), available both SPCO and DPCO output. The output relay energises when the voltage rises above the set level controlled via a potentiometer adjustable -20% to +30% of the nominal voltage. The output relay will then de-energise when the voltage falls below the set level less a hysteresis adjustable via a second potentiometer 5 to 25% of the set level. If the total supply is lost deenergisation will also occur. A green LED indicates a voltage is present and a red LED indicates that the output relay is energised.
