Electronic Healthy Phase Selector (Ats)

The Electronic Healthy Phase Selector (ATS) protects industrial and domestic equipment from power surges and fluctuations. It maintains a constant single-phased power supply from a 3-phase 4-wire input by continually monitoring each phase, automatically switching between them and returning to priority phase as necessary. The PEF-301 is a high quality, ultra-reliable, microprocessor controlled device which will ensure the safety of your equipment. Its cost is negligible when you consider the damage that might be caused to your equipment if you dona t use protection. The Electronic Healthy Phase Selector is a necessary device for a multitude of applications. Telecom, security, refrigeration, computer, industrial, office and home use appliances all need PEF-301 protection to maintain a constant load and increase their life. Connection to a UPS alone, is not enough. This device can also be used as an Auto Transfer Switch (ATS) because of its priority phase logic and delay timers.
