SELECTED OPTION:
CURRENT: 63A
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 protection 2. Under-voltage protection 3. Zero line break protection 4. Phase failure protection 5. Phase order protection (reverse phase protection) (Opition) 6. Three-phase voltage unbalance protection
Parameters: Rated voltage: 3 phase 4 wires 230V/400VAC 50/60Hz Rated current: 63A/80A Power on time: 2s (System self-test) Delay time after power-on: 40s Overvoltage protection value range: 280V±5V Overvoltage recovery value range: 250V±5V Undervoltage protection value range: 170V±5V Undervoltage recovery value range: 185V±5V OV and UV protection action time: 0.1s 3 phases volt unbalance protection value: 35% default, or customised 3 phases volt unbalance protection action time:1s Power off protection time: 0.1s Failure recovery delay time: 40s Faulty Signal: LED Grounding system: TT, TN-S, TN-C-S Installation:DIN rail Electrical isolation strength: >2000VAC, pulse: 2.5KV 1.2/50S Temperature: -20aﾣC+50aﾣC Humidity:85% Altitudea2000 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.
Package included: 1 x Voltage protector 1 x English Manual
