1. SCR power regulator adopts proportional output, harmonic is lower than THID% 5%, and meets the strict requirements of American Power Company IEEE519 (Note: Taiwan Power Company follows the American Electric Power Company specifications).
2. It is required to apply a low harmonic environment to a constant temperature and humidity heating system.
3. The protection device of this controller: (1) The source is out of phase. (2) Fuse disconnection detection. (3) The controller heat sink is over temperature protection. (4) Abnormal output contact, providing remote monitoring use, contact capacity 240VAC/5A.
4. This controller has CE international safety certification standards.
5. With R.S.T each phase fuse disconnection indicator, and provide abnormal output contacts, can be used for system emergency control.
6. The cooling fan action has temperature control, 'When the heat sink temperature is 55oC, it stops at 45oC, which can increase the fan life by 2~3 times.
7. Using low harmonic SCR power regulator, can reduce the amperage of active filter or passive filter, the active filter market price is about 1 amp 5000~8000 yuan, using low harmonic SCR power regulator 1 Ampere is only 1/20 of the price of the active filter.
