Product Description

PROTIME's APSS is micro controller based Automatic Phase Selector Switch used for Single phase Loads with Three Phase Input Supply. It is used for uninterrupted Supply to Single phase Load, when the phase form which the load is driven fails, it switch-over the load immediately to the other phase available in the 3-phase supply system. The unit also shifts the load even when voltage of the supplying phase goes out of U/V-O/V range (Settable-inside). Thus its useful for un-manned operations & saves the energy of alternate sources , when only 1 phase fails for load shedding or may be failure of fuse or any other cause. The connection is very simple with 3-phase input & 1 Phase output. It is available for Standard ratings of 6A, 16A, 32A & 63A.

Effortless Phase Management

This Automatic Phase Selector Switch simplifies continuity in power supply by instantly switching to the healthiest phase during failure. Its automatic selection process is seamless and ensures minimal interruption. Designed for both industrial and residential applications, it maintains stable operations for essential devices, even in challenging conditions.

Comprehensive Protection Features

Safety is at the core of this device, featuring a robust metal enclosure, built-in fusing, and high insulation resistance. LED indicators provide real-time updates on phase availability, while the panel-mount design fits standard installations. Its IP20 rating shields sensitive components from dust and accidental contact, extending product life.

FAQ's of Automatic Phase Selector Switch:

Q: How does the automatic phase selector switch determine the healthiest available phase?

A: The switch continuously monitors the 3-phase, 4-wire input supply. It automatically selects the phase with the most stable voltage and supplies it to the single-phase output, ensuring your load always receives uninterrupted power from the optimal phase.

Q: What benefits does the LED indicator offer in this phase selector switch?

A: The integrated LED indicators provide clear, instant visual feedback on phase availability, helping users identify which phases are active and if any faults have occurred, aiding quick diagnosis and reducing downtime.

Q: When should I use this automatic phase selector switch in my installation?

A: This device is ideal for use in both industrial and residential panel boards, especially in areas where phase imbalances or failures are common. By ensuring a continuous supply to critical loads, it protects equipment and enhances operational reliability.

Q: Where can this product be mounted, and what is its typical installation process?

A: The selector switch is designed for standard panel mounting, fitting into a space approximately 180mm x 120mm x 75mm. Installation involves integrating it into the panel board where three-phase supply and a neutral are available, following standard electrical safety procedures.

Q: What built-in protection features does this switch offer during operation?

A: The device incorporates fuse protection to guard against over-currents, IP20-rated dust and contact protection, and a metal enclosure for mechanical durability. It also tolerates high humidity and temperature variations, ensuring safe, long-term use.

Q: How much power does the device consume during normal operation?

A: The phase selector operates with high efficiency, consuming less than 5W of power during use, making it an energy-saving solution for continuous phase management.
