Over Voltage protection Value Adjustment Chart
Description: OFF means the closing position, the recovery value for the corresponding protector protection trip can automatically close the value. The unit of value is V. The following is the over voltage adjustable gear value and the corresponding over voltage recovery gear value, under voltage adjustable gear value and the corresponding under voltage recovery gear value.
Adjustable digital display reconnect over-voltage protection device, mainly used for photo-voltaic grid, household and similar use of low-voltage distribution lines, when the over voltage, under voltage or failure can automatically disconnect, and Can automatically detect the line voltage, when the line voltage returns to normal, automatic reconnect the power
The neutral line will not cut off when the product cut off the power.
The product features:
Over-voltage protection threshold adjustable, user-friendly environment according to the real-time voltage protection range. Effective protection of the user load and the safe operation of electrical appliances.
The line due to large capacitive or inductive load instantaneous start and stop caused by transient over-voltage or short-term interruption, the protector does not malfunction, and can absorb instantaneous lightning surge voltage, with a certain lightning protection function.
The protector itself has a high voltage withstand capacity, line fault voltage continues to 440V, the protector can safely protect the function itself will not be damaged.
- The effective voltage display range: 70 ~ 400V.
- Withstand lightning surge voltage: 5KV.
- Mounting : 35mm Din rail mount
