Overvoltage 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 overvoltage adjustable gear value and the corresponding overvoltage recovery gear value, undervoltage adjustable gear value and the corresponding undervoltage recovery gear value.
| OverVoltage | OFF | 235 | 240 | 245 | 250 | 255 | 260 | 265 | 270 | 275 |
| Recovery | 265 | 230 | 235 | 240 | 245 | 245 | 250 | 250 | 253 | 255 |
| Undervoltage | OFF | 160 | 165 | 170 | 175 | 180 | 185 | 190 | 195 | 200 |
| Recovery | 85 | 170 | 175 | 180 | 185 | 185 | 190 | 195 | 200 | 205 |
Product overview:
- Adjustable digital display reconnect over-voltage protection device, mainly used for photovoltaic grid, household and similar use of low-voltage distribution lines, when the over voltage, undervoltage 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 the safe operation of electrical appliances.
- the line occurred when the over-voltage cut off the line in time, the line voltage returned to normal when the delay automatically connected to the line, without manual operation.
- when the line automatically occurs when the power outage, automatic delay when the call closure, can be used for photovoltaic grid protection and anti-island protection.
- 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 surge voltage: 5KV.
- 35mm Din rail mount
