Description
Description:STVP series SINOTIMER brand automatic over-voltage and under-voltage protector is suitable for three-phase AC 380V, 50/60Hz, rated working current 80A.Its main feature is when the circuit has over-voltage or under-voltage problems, the product can cut off the power supply instantaneously to protect the electrical equipment from being damaged, besides,the protector can automatically turn on the power supply when the circuit voltage returns to the normal.
Features:
1. Over-voltage protection2. Under-voltage protection3. Zero line break protection4. Phase failure protection5. Phase order protection (reverse phase protection) (Opition)6. Three-phase voltage unbalance protection
Parameters:
Rated voltage: 3 phase 4 wires 230V/400VAC 50/60HzRated current: 63A/80APower on time: 2s (System self-test)Delay time after power-on: 40sOvervoltage protection value range: 280V±5VOvervoltage recovery value range: 250V±5VUndervoltage protection value range: 170V±5VUndervoltage recovery value range: 185V±5VOV and UV protection action time: 0.1s3 phases volt unbalance protection value: 35% default, or customised3 phases volt unbalance protection action time:1sPower off protection time: 0.1sFailure recovery delay time: 40sFaulty Signal: LEDGrounding system: TT, TN-S, TN-C-SInstallation:DIN railElectrical isolation strength: >2000VAC, pulse: 2.5KV 1.2/50?STemperature: -20?C?+50?CHumidity:?85%Altitude??2000 m
Remark:
1. The default protection voltage imbalance rate is 35% and the recovery value is 25%.Voltage unbalance rate = (highest phase voltage-lowest phase voltage) / highest phase voltage * 100%.2. When the phase order of the incoming line is wrong, the green and red lights flash at the same time, and the yellow light flashes once every three seconds. Please change L1 and L2.
