Description

• Product Name: Automatic Line Changer 
• Model No: MALC25A
• Load Capacity: 25 Amp
• Input Source: Grid / Generator / Any Other AC Supply
• Grid Supply Range: Single Phase
• Service Warranty: 24 Months

Working Mechanism:

Power Source Inputs

• The device can be connected to two AC supply sources (e.g., Main Grid Power and Generator or Main Grid and Inverter).
• Each source is wired to a separate input terminal of the ALC.

Decision Logic

• An internal control circuit (relay-based) decides whether to stay on the current source or switch to an alternate source.
• The decision is based on priority line 1 (e.g., Main Grid → Generator → Inverter).

Switching Operation

• Electromagnetic contactors or relays physically disconnect the load from the failing source before connecting it to the healthy source.
• This is typically done with break-before-make switching to avoid short-circuiting two sources.
