Digital power control manufacturer
- Three single phase controllers in one unit to save space and expense.
- Operated by one temperature controller(output is same) or three temperature controllers(separate operation). And also used as one three phase regulator(Only on three-phase four-wire system)
- With high accuracy, stability and reliability.
Feature
Three in One
- One unit including three single phase regulators saves space.
- Suitable for multiple power regulators or SSR’s.
- Different control method or different rated current can be mixed up.
- Capable to be used three single phase regulators or one three phase regulator(Three phase four wire system)
- Operated by three temperature controllers or just one temperature controller.
Saving expense and space
- More economical and more spacious than three single phase regulators.
Accuracy, Stability and Reliability
- Accuracy is enhanced by compensation algorithm comparing to different regulators.
- Long experience and know-how for digital technology since its first domestic digital power regulator allows it to be placed on the top of stability and reliability.
Ordering Code
| ① NO. of phase | S : Single phase |
| ② Control method | Note 1) P : Phase-Angle Z : Zero-Crossing |
| ③ Model | M : Multi-Type |
| ④ Rated voltage | 1 : 110V / 2 : 220V / 3 : 380V / 4 : 440V |
| ⑤ Rated current | 25A ~ 160A |
| ⑥ Option | Note 2) Additional 60℃ temperature sensor installation |
| ⑦ Cooling | 25A, 40A : Cooling fan option / More than 55A Cooling fan basically installed |
Note 1) Control method is fixed when ordering.
Note 2) 60℃ temperature sensor is installed as an option, there is no alarming but just bimetal switch is on when temperature of heatsink reaches 60℃.
