높이 = 66.5mm RS PRO 3-Phase Failure Sequence & Under-Voltage Relay The RS PRO 3-Phase voltage monitoring relay is used for connecting to a 3-wire or 4-wire supply. The relay is designed to monitor its own supply and in conjunction with an external contactor, disconnect the supply to the load/equipment in the event of a fault occurring.How does it work?For the output relay to energise, all phases (and neutral ??if applicable) must be present and measured phase voltages within the set trip levels. The product does not monitor phase rotation/sequence. If any of these conditions are not met, the relay (+ contactor) will de-energise, disconnect the supply and thus protect the equipment.Features and BenefitsCompact 17.5mm DIN rail housing Microprocessor based True R.M.S. monitoring measuring phase to phase (3wire) or phase to neutral (4-wire) voltages Selectable nominal voltages to suit most popular 3-wire or 4wire supply voltages Monitors own supply and detects an Under-voltage condition on one or more phases Detects incorrect phase sequence, phase loss and neutral loss1 Adjustment for Under voltage trip level Adjustment for Time delay DPDT relay output 5A Green LED indication for supply status Red LED indication for relay statusElectrical SpecificationInput: L1, L2, L3, N Supply/monitoring voltage Un: There are 6 nominal voltages to choose from on this product 3-wire monitoring: 380, 400, 415V AC 4-wire monitoring: 220, 230, 240V AC Frequency range: 48 ??63Hz Supply variation: 243- 540V AC (L>L) Overvoltage category: III (IEC 60664) Rated impulse withstand voltage: 4kV (1.2/50 μS) Power consumption (max.): 2.5VA Output: 15, 16, 18 / 25, 26, 28 Relay configuration: DPDT Output rating: AC1 ??250V 5A, AC15 ??250V 2A, DC1 ??25V 5A Electrical life: ??150,000 ops at rated load Dielectric voltage: 2kV AC (rms) IEC 60947-1 Rated impulse withstand voltage: 4kV (1.2/50μS) IEC 60664
